00:00:00,320 --> 00:00:03,320
Today we're covering some really
interesting research on grip 

2
00:00:03,320 --> 00:00:06,080
pressure, how tightly you're 
gripping the club. 

3
00:00:06,080 --> 00:00:09,320
And we're not just talking about
like it's set U like how tight. 

4
00:00:09,320 --> 00:00:11,000
Your grip should be but. 
All throughout the swing. 

5
00:00:11,000 --> 00:00:12,960
Like what about a transition at 
the top of the back swing? 

6
00:00:12,960 --> 00:00:16,160
What about an impact? 
We have a really great study 

7
00:00:16,160 --> 00:00:17,920
we're looking at with Liam 
Mucklow. 

8
00:00:18,200 --> 00:00:21,240
We're talking about his work 
that he's done with pressure 

9
00:00:21,240 --> 00:00:24,680
sensors into grips. 
I looked at high handicappers, 

10
00:00:24,680 --> 00:00:27,200
people that hook the ball, slice
the ball, and pros. 

11
00:00:27,200 --> 00:00:30,200
So really good data. 
I'm super excited to dive into 

12
00:00:30,200 --> 00:00:32,720
this with him. 
We recorded this a little while 

13
00:00:32,720 --> 00:00:36,840
back for folks on our newsletter
who got the first sneak peek of 

14
00:00:36,840 --> 00:00:38,080
this.

All right, let's go do it. 

21
00:00:55,440 --> 00:00:56,360
OK. 
Yeah, all. 

22
00:00:56,880 --> 00:01:00,200
Right. 
OK, so here's like, I think the 

23
00:01:00,200 --> 00:01:04,000
biggest thing, biggest simple 
thing is like, oh, but I was 

24
00:01:04,000 --> 00:01:06,240
supposed to hold it as a three 
out of 10. 

25
00:01:07,720 --> 00:01:10,560
Like, OK, well, there's a lot of
layers to feel back there, but 

26
00:01:10,560 --> 00:01:15,520
what I've got here, this graph 
on the right, this is showing 

27
00:01:15,920 --> 00:01:20,920
percentage of maximum grip 
pressure for that golfer type. 

28
00:01:21,200 --> 00:01:24,320
OK, so we got our legend up here
with you, right? 

29
00:01:24,320 --> 00:01:26,440
So we have our playing 
professional. 

30
00:01:26,440 --> 00:01:28,680
We've got the person that 
chronically fights a Hulk. 

31
00:01:28,680 --> 00:01:31,320
We've got the high handicapper 
that just struggles with contact

32
00:01:31,320 --> 00:01:33,560
in general. 
And then we've got, you know, 

33
00:01:33,560 --> 00:01:36,120
like your classic slicer. 
Yeah. 

34
00:01:37,240 --> 00:01:40,320
So first thing I want to do is 
take a look at at setup. 

35
00:01:40,440 --> 00:01:43,600
So if we look at the height 
kneecapper and the slicer, well,

36
00:01:43,600 --> 00:01:45,680
First off, they're way below 3 
out of 10. 

37
00:01:45,720 --> 00:01:48,120
They're like below 1 out of 10. 
They're barely holding it. 

38
00:01:48,560 --> 00:01:50,600
OK, so they've got a little 
overboard there. 

39
00:01:51,040 --> 00:01:56,800
Even even the the hooker here is
like below 25%, they're below 3 

40
00:01:56,800 --> 00:02:00,240
out of 10. 
Now we get here, it's like a 

41
00:02:00,240 --> 00:02:03,800
four 4 1/2 out of 10 for the 
Tour Pro. 

42
00:02:03,800 --> 00:02:07,640
So this is to me, this is where 
it gets interesting. 

43
00:02:09,440 --> 00:02:11,240
Take a look at the grip 
strengths over here. 

44
00:02:12,080 --> 00:02:15,680
So this is from the PowerPoint. 
So the average combined grip 

45
00:02:15,680 --> 00:02:18,760
strength of those two hands is 
276 lbs. 

46
00:02:19,400 --> 00:02:24,280
Now we times that by the actual,
you know, amount of pressure, 

47
00:02:24,600 --> 00:02:26,560
you know, the percentage of Max 
pressure. 

48
00:02:26,920 --> 00:02:33,760
And I got like 124 lbs OK, like 
not too far off a three out of 

49
00:02:33,760 --> 00:02:35,960
10. 
But what I don't think amateur 

50
00:02:35,960 --> 00:02:39,360
golfers ever take into account 
is the person who's saying they 

51
00:02:39,360 --> 00:02:42,360
feel like it's a 3 out of 10 
hits golf balls all day every 

52
00:02:42,360 --> 00:02:45,880
day and hits them hard. 
And like, this is what they do. 

53
00:02:45,880 --> 00:02:48,320
So they've got if anyone out 
there has ever actually shook 

54
00:02:48,320 --> 00:02:51,760
hands with a tour pro, they got 
a pretty serious grip. 

55
00:02:52,080 --> 00:02:56,960
Yeah, within group 2 we had we 
had one guy who competes in long

56
00:02:56,960 --> 00:02:59,760
drive, which to be honest, I 
think it kind of skewed the grip

57
00:02:59,760 --> 00:03:02,120
strength a little higher than 
what we would normally see. 

58
00:03:03,640 --> 00:03:06,480
The other thing I'll notice so 
when you see this differential 

59
00:03:06,480 --> 00:03:11,600
13.4 lbs, that means on average 
the lead hand, the left hand for

60
00:03:11,600 --> 00:03:15,080
the right-handed golfer was 
about 13 1/2 lbs stronger than 

61
00:03:15,080 --> 00:03:18,360
the right, huh. 
So anyway, we're let's go let's 

62
00:03:18,360 --> 00:03:23,920
go back to this 124 number. 
OK OK now we're down here at 

63
00:03:23,920 --> 00:03:26,760
our, you know, high handicap or 
poor contact player. 

64
00:03:27,120 --> 00:03:33,040
Well, their Max is only 147, so 
if they actually wanted to match

65
00:03:33,560 --> 00:03:36,680
what, you know, what the tour 
Pro is doing from, I'll call it 

66
00:03:36,680 --> 00:03:42,080
like a global perspective, not a
three out of 10, but 124 lbs. 

67
00:03:42,080 --> 00:03:44,120
They'll be way up here at like a
nine out of 10. 

68
00:03:46,440 --> 00:03:47,480
Got it. 
So got it. 

69
00:03:47,800 --> 00:03:52,440
Yeah, like obviously there's a 
lot there to digest, but I think

70
00:03:52,560 --> 00:03:58,360
to me the simple basic is like 
99% of amateur golfers would be 

71
00:03:58,360 --> 00:04:01,160
better off to squeeze the club 
tighter in a dress. 

72
00:04:01,920 --> 00:04:05,880
Got it. 
So we've got, we've got this 

73
00:04:05,880 --> 00:04:07,760
aspect of obviously our 
professional golfers are 

74
00:04:07,760 --> 00:04:10,400
swinging harder than the 
amateurs that you're, you're 

75
00:04:10,520 --> 00:04:12,880
talking about too, right? 
Like I swing faster. 

76
00:04:14,760 --> 00:04:18,240
In there, they're gripping it 
harder to to set up. 

77
00:04:18,240 --> 00:04:22,400
Do you think it's, do you think 
they swing faster because they 

78
00:04:22,400 --> 00:04:24,480
grip it harder or they grip it 
harder because they swing 

79
00:04:24,480 --> 00:04:28,080
faster? 
Man, that that's the toughest 

80
00:04:28,080 --> 00:04:30,680
part about this study of 
pressure because there's also 

81
00:04:30,680 --> 00:04:33,400
like this thing you don't know, 
I'll put that grip pressure 

82
00:04:33,400 --> 00:04:35,720
graph back up and we'll start to
talk our way through it. 

83
00:04:35,720 --> 00:04:39,080
But it's like there's certain 
points where the golfer is 

84
00:04:39,080 --> 00:04:41,920
applying pressure to the handle 
of the club and there's certain 

85
00:04:41,920 --> 00:04:44,400
points where the handle of the 
club is applying pressure to the

86
00:04:44,400 --> 00:04:49,840
golfer. 
OK, so, yeah, so it gets, you 

87
00:04:49,840 --> 00:04:51,960
know, there, there's some Gray 
area now. 

88
00:04:51,960 --> 00:04:59,680
I, I, I think you know, to me, I
think, you know, there's a, 

89
00:04:59,680 --> 00:05:02,800
there's a couple things at play.
What, what I've noticed now 

90
00:05:02,800 --> 00:05:05,840
since having this information, 
starting to have dialogue with 

91
00:05:05,840 --> 00:05:08,800
amateur players about it. 
I think one of the most 

92
00:05:08,800 --> 00:05:12,760
important things is that there 
has to be a match between the 

93
00:05:12,760 --> 00:05:16,320
grip pressure application and 
the resultant body movements of 

94
00:05:16,320 --> 00:05:20,240
the player. 
So I don't think you'll be able 

95
00:05:20,240 --> 00:05:24,320
to make an exact match to the 
pressure distribution pattern 

96
00:05:24,520 --> 00:05:26,920
unless you move your body in a 
similar way. 

97
00:05:28,240 --> 00:05:31,240
And if we look into some of the 
individual swings, we can kind 

98
00:05:31,240 --> 00:05:33,960
of dive a little bit deeper into
there. 

99
00:05:33,960 --> 00:05:36,720
But if, if we're not changing 
body movements, but we're 

100
00:05:36,720 --> 00:05:40,640
changing grip pressure, it's 
quite likely that the club will 

101
00:05:40,640 --> 00:05:44,520
be out of sync with the body and
we won't get that increased 

102
00:05:44,520 --> 00:05:49,040
performance. 
I do feel, you know, again, for 

103
00:05:49,040 --> 00:05:51,480
these amateurs, 99% of them, 
we're going to be better off 

104
00:05:51,480 --> 00:05:57,240
squeezing it tighter. 
It's so loose that it's like 

105
00:05:57,360 --> 00:05:59,960
they're losing energy created by
our body. 

106
00:06:00,800 --> 00:06:03,520
And it's the last, you know, 
it's our only connection to the 

107
00:06:03,520 --> 00:06:06,840
club. 
And if that's not secure, we're 

108
00:06:06,840 --> 00:06:09,400
going to have energy that we 
generate with our body leak out 

109
00:06:09,400 --> 00:06:11,880
and not transferred to the club,
you know. 

110
00:06:11,880 --> 00:06:14,840
So I think, I think that's one 
of the most important for the 

111
00:06:15,640 --> 00:06:19,280
conceptual things, I guess. 
So is it that we're we're doing 

112
00:06:19,280 --> 00:06:22,800
so much work with our body to 
try to swing hard, but then 

113
00:06:22,880 --> 00:06:27,320
we're gripping it too lightly? 
So the club is is the club is 

114
00:06:27,320 --> 00:06:29,200
actually controlling it instead 
of our hands? 

115
00:06:29,720 --> 00:06:30,800
Is that a way to say it? 
Yeah. 

116
00:06:31,600 --> 00:06:35,960
No, I, I like that, especially 
when we look, I'm going to throw

117
00:06:35,960 --> 00:06:40,640
up another. 
I'm going to throw up another 

118
00:06:40,640 --> 00:06:43,840
image here. 
Let's look at the let's look at 

119
00:06:43,840 --> 00:06:48,560
the high Handycamper. 
OK, now this is getting so this 

120
00:06:48,560 --> 00:06:53,960
is getting a little heavy here. 
Let me just get the slideshow a 

121
00:06:53,960 --> 00:06:59,360
little like, so here's like the 
latest round of I don't know, 

122
00:06:59,360 --> 00:07:03,160
process and we'll call it there.
There is there's so much data in

123
00:07:03,160 --> 00:07:06,960
this study from the swing 
catalyst motion plate to the 

124
00:07:06,960 --> 00:07:11,760
full body gears. 
We use Forsythe GC quad for this

125
00:07:11,760 --> 00:07:16,480
one, plus the sensor grip. 
So this to me is super 

126
00:07:16,480 --> 00:07:18,880
fascinating. 
It's overlaid with the kinematic

127
00:07:18,880 --> 00:07:21,360
sequence. 
And so we've kind of put these 

128
00:07:21,360 --> 00:07:25,200
little body position avatars to 
try and help people that don't 

129
00:07:25,200 --> 00:07:27,560
look at this stuff every day 
understand where we're at. 

130
00:07:28,600 --> 00:07:30,640
And I think this is super 
fascinating. 

131
00:07:30,640 --> 00:07:36,040
So the orange line is showing me
the rotational speed of the 

132
00:07:36,040 --> 00:07:39,600
club, OK, when it's down here 
where my, I'm not sure if can 

133
00:07:39,600 --> 00:07:41,560
you see my cursor right now? 
Yeah, there. 

134
00:07:41,560 --> 00:07:42,240
We go. 
I can, yeah. 

135
00:07:42,840 --> 00:07:47,520
So when it's down here, that's 
the club is rotating away from 

136
00:07:47,520 --> 00:07:51,520
the target, OK, It's up here, 
it's rotating towards a target. 

137
00:07:52,480 --> 00:07:56,440
And so we see this, you know, 
super, super, super low growth 

138
00:07:56,440 --> 00:07:59,200
pressure. 
And as the club starts to 

139
00:07:59,200 --> 00:08:03,360
accelerate to me, and I'm just 
telling you how I read this, I 

140
00:08:03,360 --> 00:08:05,560
can't tell you if it's right, 
This is just what I'm kind of 

141
00:08:05,760 --> 00:08:09,560
the way I see it, the group 
pressure starts to ramp up a 

142
00:08:09,560 --> 00:08:12,720
little bit as the club picks up 
some speed. 

143
00:08:14,240 --> 00:08:19,600
Now right here where we get, you
know, that line farthest down 

144
00:08:19,600 --> 00:08:23,360
below the horizontal axis, 
that's the fastest the club is 

145
00:08:23,360 --> 00:08:25,120
rotating back away from the 
target. 

146
00:08:25,880 --> 00:08:29,120
And I'm like right at that 
moment in time, it's like this 

147
00:08:29,120 --> 00:08:32,480
high handicapper just grabs on 
for life and they're along for 

148
00:08:32,480 --> 00:08:35,400
the ride. 
OK, you know, And then if, you 

149
00:08:35,400 --> 00:08:39,640
know, we look transition to the 
downswing, Well, whichever line 

150
00:08:39,640 --> 00:08:43,320
is highest up here is rotating 
fastest to the target. 

151
00:08:43,840 --> 00:08:47,400
Well, right from the beginning, 
that club is rotating the faster

152
00:08:47,400 --> 00:08:49,560
the target than any other part 
of the body. 

153
00:08:49,560 --> 00:08:52,480
And it's like, yeah, they're 
gloves leading the way, and 

154
00:08:52,480 --> 00:08:55,240
they're just squeezing on for 
dear life, hanging on for a 

155
00:08:55,240 --> 00:08:57,520
ride, you know, kind of like, I 
don't know, maybe your first 

156
00:08:57,520 --> 00:08:59,720
trip on a roller coaster when 
you were 12 years old. 

157
00:08:59,720 --> 00:09:01,960
I'm just hanging on trying to 
stay in the car. 

158
00:09:02,560 --> 00:09:07,040
OK. 
So it's just, yeah, really high 

159
00:09:07,040 --> 00:09:11,680
pressure from like kind of, I 
don't know if it's arm parallel 

160
00:09:11,680 --> 00:09:15,160
on the backswing. 
Give or take somewhere between 

161
00:09:15,160 --> 00:09:17,960
shaft parallel and arm parallel 
in the backswing, yeah. 

162
00:09:18,160 --> 00:09:21,920
All the way through impact, it's
it's kind of just grip. 

163
00:09:22,000 --> 00:09:25,920
Then then they decide to grip. 
Yeah. 

164
00:09:25,920 --> 00:09:28,760
And then it's like then they 
they lock on like, you know, 

165
00:09:29,320 --> 00:09:31,920
this, you know, with their 
maximum grip pressure. 

166
00:09:32,440 --> 00:09:34,800
And what's also interesting, 
we'll look at a couple other 

167
00:09:34,800 --> 00:09:38,880
ones. 
This it kind of the circular 

168
00:09:38,880 --> 00:09:43,360
dotted line, that's the trail 
hand, the right hand, because 

169
00:09:43,520 --> 00:09:46,920
this dash line, that's the lead 
hand, the left hand. 

170
00:09:48,120 --> 00:09:51,520
The high handicappers were also 
the only group that had higher 

171
00:09:51,520 --> 00:09:54,800
pressure was the bottom hand. 
Every other group had higher 

172
00:09:54,800 --> 00:09:55,960
pressure with the top. 
Hand. 

173
00:09:56,440 --> 00:10:00,240
Interesting. 
Do they have the most rotation 

174
00:10:00,320 --> 00:10:03,760
happening? 
They had the least amount of 

175
00:10:03,760 --> 00:10:07,520
body, well that impact, they had
the least amount of body 

176
00:10:07,520 --> 00:10:11,080
rotation. 
OK, the the slicer you want to 

177
00:10:11,080 --> 00:10:13,120
you want to look at hooker or 
slicer next? 

178
00:10:13,560 --> 00:10:14,720
Let's. 
Look at hooker. 

179
00:10:15,000 --> 00:10:20,280
OK, so so the hooker started, 
you know, with the grip pressure

180
00:10:20,280 --> 00:10:22,400
that was closest to the amount 
to the professional. 

181
00:10:22,400 --> 00:10:25,080
Remember the professionals were 
way up here, still about double 

182
00:10:26,720 --> 00:10:29,400
and it's a little bit more 
controlled. 

183
00:10:29,400 --> 00:10:32,600
But again, we see this same 
thing keep happening when this 

184
00:10:32,600 --> 00:10:36,640
club is it maximum rotational 
speed away from the target. 

185
00:10:36,640 --> 00:10:39,280
It's like within every group, 
there's this little spike in 

186
00:10:39,280 --> 00:10:44,600
grip pressure. 
Now what what we noticed and 

187
00:10:44,600 --> 00:10:50,800
it's it's pretty difficult to 
tease out of this grass there 

188
00:10:50,800 --> 00:10:53,200
was. 
So well, First off, let's take a

189
00:10:53,200 --> 00:10:55,000
look. 
This dotted line right when the 

190
00:10:55,000 --> 00:10:59,760
golfer starts down, this hooker 
really starts to squeeze hard 

191
00:10:59,760 --> 00:11:03,080
with the left hand. 
The right hand goes up a little 

192
00:11:03,080 --> 00:11:06,120
bit, but not nearly as much as 
the left. 

193
00:11:06,440 --> 00:11:12,040
OK, So what we saw was a real 
ramp up in left hand grip 

194
00:11:12,040 --> 00:11:15,280
pressure, but very low pelvis 
rotation. 

195
00:11:16,160 --> 00:11:20,080
So it's like they're squeezing 
the club, dropping it down this 

196
00:11:20,080 --> 00:11:23,080
way and instead of rotating, 
they're kind of just sliding the

197
00:11:23,120 --> 00:11:26,840
hips forward, you know, side 
bending away from the target, 

198
00:11:26,840 --> 00:11:30,120
which makes sense for, to me 
anyway, for the club being, you 

199
00:11:30,120 --> 00:11:32,880
know, dumped behind. 
Yep, yeah, it's. 

200
00:11:32,880 --> 00:11:37,080
Way behind them and now, you 
know, in here you can see we're 

201
00:11:37,080 --> 00:11:40,640
coming up on impact with shaft 
parallel on the way down and 

202
00:11:40,640 --> 00:11:43,880
it's again just this is the way 
I read it. 

203
00:11:44,000 --> 00:11:47,560
I'm look, it's like the golfer 
knows I got the club stuck so 

204
00:11:47,560 --> 00:11:49,480
far behind and it's going so far
inside out. 

205
00:11:49,480 --> 00:11:52,840
It's like, Oh my God, I better 
flip it back to square with the 

206
00:11:52,840 --> 00:11:55,720
right hand right. 
You see that, you know, I got 

207
00:11:55,720 --> 00:11:59,000
ourself that my whole life so. 
Got it. 

208
00:12:00,600 --> 00:12:02,480
So, you know, kind of 
interesting there. 

209
00:12:07,040 --> 00:12:09,360
I'm sorry, I guess I need I need
a clarification. 

210
00:12:09,640 --> 00:12:12,200
Could you define? 
Total pressure again cuz cuz the

211
00:12:12,200 --> 00:12:14,280
total pressure of the high 
handicap was higher. 

212
00:12:14,360 --> 00:12:16,560
So I'm missing I'm missing 
something mentally here? 

213
00:12:16,680 --> 00:12:18,200
Total pressure. 
No, no. 

214
00:12:18,200 --> 00:12:21,960
So that we'll talk about I got 
AI, got a baseball back here. 

215
00:12:22,120 --> 00:12:24,840
So so we take the sensor grip 
club. 

216
00:12:25,120 --> 00:12:27,240
Yeah. 
And then it's like, you know, 

217
00:12:27,240 --> 00:12:30,240
the software prompts, squeeze it
as tight as you can in the left 

218
00:12:30,240 --> 00:12:32,680
hand. 
OK, OK, yeah. 

219
00:12:32,680 --> 00:12:36,080
And then squeeze it as tight as 
you can in the right hand and 

220
00:12:36,080 --> 00:12:38,360
then squeeze it as tight as you 
can with both hands. 

221
00:12:39,760 --> 00:12:41,640
Got it. 
And that, that and that's what 

222
00:12:41,640 --> 00:12:47,760
determines the 100%. 
That's also what sets the split 

223
00:12:48,320 --> 00:12:51,280
location for lead, hand and 
trail. 

224
00:12:51,880 --> 00:12:53,760
OK. 
Pretty important stuff. 

225
00:12:54,200 --> 00:12:58,120
Now we'll go just because this 
is not complicated enough, we're

226
00:12:58,120 --> 00:13:00,720
going to go back to this high 
handicapper because I want you 

227
00:13:00,720 --> 00:13:04,440
to notice, Yeah, they actually 
get up above 100% here with the 

228
00:13:04,440 --> 00:13:06,000
right hand. 
OK, Yeah. 

229
00:13:06,240 --> 00:13:08,680
And, and that's what I was 
talking about is there's periods

230
00:13:08,680 --> 00:13:12,920
in time when the club is pushing
back into the player. 

231
00:13:14,000 --> 00:13:17,400
And so that's how they're able 
to get a higher pressure than 

232
00:13:17,400 --> 00:13:19,880
what they could actually just 
stand there and squeeze it with.

233
00:13:20,240 --> 00:13:21,840
Interesting. 
OK. 

234
00:13:22,880 --> 00:13:25,800
That makes sense. 
I I get it. 

235
00:13:25,840 --> 00:13:27,960
Yeah, Yeah. 
Especially if they're, you know,

236
00:13:27,960 --> 00:13:29,880
as I kind of put it along for 
the ride. 

237
00:13:30,200 --> 00:13:33,520
And that's that's not a good 
thing though, like being able to

238
00:13:33,520 --> 00:13:37,080
produce more than 100% of force 
that that's not a helpful thing.

239
00:13:38,440 --> 00:13:42,960
Well, we didn't see it happen 
with any good players in this. 

240
00:13:43,000 --> 00:13:45,920
OK, OK, so. 
Yeah, yeah. 

241
00:13:46,280 --> 00:13:48,800
Now, you know, the other thing I
think is important for people 

242
00:13:48,800 --> 00:13:52,480
out there to know too is like, 
this is brand new technology, 

243
00:13:52,880 --> 00:13:57,080
you know, And so as we use it 
more, there may be ways we could

244
00:13:57,080 --> 00:13:59,840
do more effective calibration. 
So one of the things we're 

245
00:13:59,840 --> 00:14:02,960
playing around with now, this 
came from Sasho when we were 

246
00:14:02,960 --> 00:14:05,560
talking over in England, is 
actually to put the the club at 

247
00:14:05,560 --> 00:14:08,480
a gripping vise. 
So I can not only grab it, but I

248
00:14:08,480 --> 00:14:11,680
can kind of twist it. 
And I think that might get that 

249
00:14:12,080 --> 00:14:14,520
100% up a little bit higher. 
Got it. 

250
00:14:14,600 --> 00:14:21,720
So, So yeah, with the, you know,
with the with the player that, 

251
00:14:22,000 --> 00:14:27,960
you know, fights the hook, we 
saw, you know, very low body 

252
00:14:27,960 --> 00:14:31,800
rotation in the first half of 
the downswing and an increase in

253
00:14:32,600 --> 00:14:34,200
lead hand pressure. 
Yep. 

254
00:14:35,320 --> 00:14:39,080
So that that was kind of a 
common trait across the sample 

255
00:14:39,080 --> 00:14:40,080
size. 
Yep. 

256
00:14:43,040 --> 00:14:50,240
When we get here to the slicer, 
you know, again, it's like 

257
00:14:51,200 --> 00:14:55,320
starts with lower pressure. 
This is more of kind of a steady

258
00:14:55,320 --> 00:14:57,520
ramp up throughout the whole 
backswing. 

259
00:14:59,840 --> 00:15:02,960
And then when I, you know, when 
we're looking at both of the 

260
00:15:02,960 --> 00:15:07,080
body movements and the grip 
pressure, we see this right 

261
00:15:07,080 --> 00:15:11,360
hand, the the circular dotted 
line, we see it really kind of 

262
00:15:11,360 --> 00:15:14,760
ramp up and I'm, and we saw a 
lot of pelvis rotation. 

263
00:15:14,760 --> 00:15:19,680
So again, I just start picturing
A golfer spinning quickly with 

264
00:15:19,680 --> 00:15:23,240
their body and pushing hard with
the right hand. 

265
00:15:23,400 --> 00:15:25,880
I'm like, Oh yeah, OK, well, 
let's slice all day. 

266
00:15:25,880 --> 00:15:31,080
That makes sense, yeah. 
And they're doing it too early, 

267
00:15:31,160 --> 00:15:34,360
right with the right hand they 
that's why that bump is early 

268
00:15:34,480 --> 00:15:35,760
with the. 
Gets it out early. 

269
00:15:36,120 --> 00:15:39,840
Yeah, you got it. 
So now hopefully this one starts

270
00:15:39,840 --> 00:15:45,480
to make a little bit more sense.
So you know, again, my 

271
00:15:45,480 --> 00:15:49,320
interpretation of this is we've 
got much higher growth pressure 

272
00:15:49,320 --> 00:15:54,240
to start with and compared to 
the other groups, relatively, 

273
00:15:54,240 --> 00:15:58,800
even relatively constant as it 
go throughout the backswing. 

274
00:15:59,840 --> 00:16:02,920
Now they're the the 
professionals, the only people 

275
00:16:02,920 --> 00:16:06,000
in the group that we saw. 
Oh man, Holy smokes. 

276
00:16:06,360 --> 00:16:08,600
I just realized I have this 
slide title wrong and it's a 

277
00:16:08,600 --> 00:16:10,320
slicer. 
It is not a slicer. 

278
00:16:10,480 --> 00:16:16,920
Sorry, folks. 
We see this little peek right at

279
00:16:16,920 --> 00:16:22,320
transition and I believe the 
peak is because the golfer has 

280
00:16:22,320 --> 00:16:26,360
to squeeze the club in order to 
stop it and have it get ready to

281
00:16:26,360 --> 00:16:30,960
change direction. 
And then we see, you know, the 

282
00:16:31,040 --> 00:16:36,040
only group, this was the only 
group of all of them that had a 

283
00:16:36,040 --> 00:16:38,840
reduction in grip pressure early
in transition. 

284
00:16:40,360 --> 00:16:44,440
So when I think about it, that's
what allows me to rotate the 

285
00:16:44,440 --> 00:16:48,880
body and kind of let the club, 
it's all behind the body. 

286
00:16:49,000 --> 00:16:50,800
You know, there's a million 
different things. 

287
00:16:50,800 --> 00:16:54,000
If you want to call it leg or 
shallow, I'll leave that up to 

288
00:16:54,440 --> 00:16:56,120
whoever wants to put those 
labels on it. 

289
00:16:56,120 --> 00:16:58,880
But that's just kind of what I 
felt like I saw. 

290
00:16:59,640 --> 00:17:02,760
And you know, once we get to 
around, you know, with the 

291
00:17:02,760 --> 00:17:04,280
different people, it varied a 
little bit. 

292
00:17:04,280 --> 00:17:08,359
But between lead arm parallel 
and shaft parallel, we see a big

293
00:17:08,720 --> 00:17:10,480
ramp up in the grip pressure 
again. 

294
00:17:12,520 --> 00:17:14,480
Yeah. 
And then for the last little bit

295
00:17:14,480 --> 00:17:17,480
on approach to the ball, we see 
it fairly neutral, fairly calm, 

296
00:17:18,000 --> 00:17:20,640
which also makes sense. 
You know, I think about how good

297
00:17:20,640 --> 00:17:24,280
those professional players are 
maintaining, you know, minimal 

298
00:17:24,280 --> 00:17:26,200
club face rotation through the 
striking so. 

299
00:17:28,240 --> 00:17:31,360
Interesting. 
It's so different than the other

300
00:17:31,360 --> 00:17:34,160
golfers, the professor, it's so 
flat. 

301
00:17:34,240 --> 00:17:38,480
It's so. 
Yeah, yeah, very different. 

302
00:17:39,480 --> 00:17:41,920
That's where we, you know, this 
latest round was trying to 

303
00:17:41,920 --> 00:17:44,840
visualize it over the course of 
the Gulf Point, you know, like 

304
00:17:44,840 --> 00:17:49,680
in in time, not just in kind of 
like, you know, because the the 

305
00:17:49,680 --> 00:17:51,960
time between each of these 
positions is definitely not 

306
00:17:51,960 --> 00:17:57,160
created equal, you know, our P1 
to P6, whatever you want to 

307
00:17:57,160 --> 00:17:58,480
look. 
Yeah. 

308
00:18:00,160 --> 00:18:04,520
So, yeah, like there's, there's 
a lot of differences. 

309
00:18:05,080 --> 00:18:09,040
There's a lot going on. 
You know, this is kind of back 

310
00:18:09,040 --> 00:18:13,280
to the normal visualization. 
I think the big thing like if we

311
00:18:13,280 --> 00:18:17,920
look at we look at the high 
handicappers, the first thing I 

312
00:18:17,920 --> 00:18:21,080
look at is how they're the only 
group that's trailhand dominant.

313
00:18:22,440 --> 00:18:26,960
So like if I'm, you know, if I'm
a high handicapper, what do I 

314
00:18:26,960 --> 00:18:28,280
make of that? 
Well, the first thing I would 

315
00:18:28,280 --> 00:18:31,800
start to do would be maybe just 
take your wedge and go do some 

316
00:18:31,800 --> 00:18:36,680
left hand only swings, you know,
and because it could be #1 get 

317
00:18:36,680 --> 00:18:38,320
the left hand grip strength 
higher. 

318
00:18:38,960 --> 00:18:42,160
So in that, in that group, when 
we tested grip strength on the 

319
00:18:42,160 --> 00:18:44,960
dynamometer, the right hand was 
stronger to begin with. 

320
00:18:44,960 --> 00:18:49,160
So let's get the left hand grip 
strength higher and let's learn 

321
00:18:49,160 --> 00:18:51,080
how to rotate our body and use 
it that way. 

322
00:18:51,960 --> 00:18:55,480
Yep. 
When I think about stuff for the

323
00:18:55,600 --> 00:18:59,040
the slicer here where in 
transition I've got that real 

324
00:18:59,560 --> 00:19:02,800
spike, early spike with the 
right hand, I think about 

325
00:19:02,800 --> 00:19:05,320
Hogan's three finger drill. 
Well, let's just take them right

326
00:19:05,320 --> 00:19:08,360
off the club, you know, and if 
they're not touching the club, I

327
00:19:08,360 --> 00:19:10,480
think it's probably harder to 
apply pressure to it. 

328
00:19:11,480 --> 00:19:13,760
That would make sense. 
Yeah, yeah, right. 

329
00:19:13,800 --> 00:19:16,760
And you know, they're already 
rotating the body, so maybe that

330
00:19:16,760 --> 00:19:20,000
gives the club the chance to 
kind of fall behind the body 

331
00:19:20,000 --> 00:19:21,840
instead of get thrown out in 
front of it. 

332
00:19:24,720 --> 00:19:30,880
If I'm if I'm here with the with
the hooker, I would say this is 

333
00:19:31,040 --> 00:19:32,840
gets tricky. 
It's kind of two things. 

334
00:19:33,920 --> 00:19:38,240
First, if we look at their right
hand grip pressure right here 

335
00:19:38,680 --> 00:19:40,560
and then we look at the pros 
right here. 

336
00:19:41,920 --> 00:19:45,440
I would want to see them kind of
do it the opposite right. 

337
00:19:45,440 --> 00:19:48,360
They're increasing left hand 
grip pressure decreasing right 

338
00:19:48,360 --> 00:19:52,400
hand as opposed to the pros 
decreasing left hand increasing 

339
00:19:52,440 --> 00:19:57,080
right now It can be a mind 
melter for sure, but I would 

340
00:19:57,080 --> 00:20:00,640
squeeze it tighter with the 
right hand in your hips early. 

341
00:20:01,480 --> 00:20:05,840
Remember they they had low hip 
rotation sliding back this way. 

342
00:20:06,440 --> 00:20:08,000
Yep. 
So turn and squeeze it with the 

343
00:20:08,000 --> 00:20:10,360
right hand. 
You might stop dumping that 

344
00:20:10,360 --> 00:20:16,240
thing so far back behind you. 
A lot of graphs, man. 

345
00:20:16,240 --> 00:20:17,800
A lot. 
Of no, it's, it's super 

346
00:20:17,840 --> 00:20:22,000
interesting. 
OK, so I guess we all can grip 

347
00:20:22,000 --> 00:20:25,560
it harder at setup, right? 
That's pretty universal. 

348
00:20:26,280 --> 00:20:29,400
I am very comfortable with that,
yes, OK. 

349
00:20:30,400 --> 00:20:33,080
I guess you you gave some 
interventions there of like 

350
00:20:33,080 --> 00:20:36,680
things that you can think about.
Have you seen is working on grip

351
00:20:36,680 --> 00:20:39,040
pressure like does that work as 
an intervention? 

352
00:20:39,040 --> 00:20:42,200
Does that change movement 
patterns or is it difficult that

353
00:20:42,200 --> 00:20:44,640
going that direction? 
It can for sure. 

354
00:20:45,920 --> 00:20:50,520
You know, I think I think a lot 
of it for the coaches out there 

355
00:20:50,880 --> 00:20:54,960
is gauge the athletic skill and 
coordination of the client. 

356
00:20:56,480 --> 00:20:59,200
If that person hasn't played any
other sports, if their body 

357
00:20:59,200 --> 00:21:03,440
awareness isn't great, you might
want to develop that stuff first

358
00:21:04,600 --> 00:21:07,680
before you, you know, start 
trying to ask some of these 

359
00:21:07,680 --> 00:21:10,600
complex athletic movements that 
are all going to be kind of 

360
00:21:10,600 --> 00:21:16,440
internal cues. 
The analogy I used when I was 

361
00:21:16,440 --> 00:21:22,000
presenting this stuff last week 
is my partner in in the baseball

362
00:21:22,000 --> 00:21:25,840
stuff, Mikey Gibbs. 
Played professional baseball, 

363
00:21:26,400 --> 00:21:30,080
college national champion, third
round draft pick, highly 

364
00:21:30,080 --> 00:21:33,240
coordinated, high level of body 
awareness. 

365
00:21:33,240 --> 00:21:36,800
We're about to play golf a 
couple weeks ago and he just 

366
00:21:36,800 --> 00:21:38,680
said, yeah, I'm just going to 
feel like my right hand is kind 

367
00:21:38,680 --> 00:21:42,880
of relaxed. 
It drove it as straight as I've 

368
00:21:42,880 --> 00:21:45,240
ever seen it. 
Gave up a couple yards, played 

369
00:21:45,240 --> 00:21:47,520
eighteen holes with 1G ball is 
pretty impressive. 

370
00:21:47,520 --> 00:21:51,240
Nice. 
My wife helps him proofread all 

371
00:21:51,240 --> 00:21:53,080
the articles and stuff that I 
write. 

372
00:21:53,080 --> 00:21:57,240
So just after we finished the 
article for Golf magazine, Wendy

373
00:21:57,240 --> 00:21:59,800
went over to the range to try 
and apply some of the grip 

374
00:21:59,800 --> 00:22:01,840
pressure stuff. 
Her background is in sailing. 

375
00:22:03,600 --> 00:22:06,840
I think she shanked 3 balls, 
accidentally threw her club once

376
00:22:06,840 --> 00:22:09,280
and then came home upset and 
said this is crap, I'm not 

377
00:22:09,280 --> 00:22:15,400
getting this. 
Yeah, you know, you kind of got 

378
00:22:15,400 --> 00:22:18,240
to gauge who you're with. 
And I think, you know, to me 

379
00:22:18,240 --> 00:22:21,280
what, what I find fascinating 
about is we've just never had 

380
00:22:21,280 --> 00:22:26,200
this intro, you know, And so 
the, the, the purpose of this 

381
00:22:26,200 --> 00:22:29,680
study was really just to try and
gather some information. 

382
00:22:29,680 --> 00:22:34,760
See, is there any common 
tendencies, you know, in these 

383
00:22:34,800 --> 00:22:40,480
golfer subsets, which I I was 
quite surprised in the 

384
00:22:40,480 --> 00:22:47,280
similarities, you know, and 
then, you know, from there, 

385
00:22:47,280 --> 00:22:48,400
Yeah. 
Like, let's just get this 

386
00:22:48,400 --> 00:22:52,120
information out there to as many
coaches, as many golfers as we 

387
00:22:52,120 --> 00:22:55,800
can start to collect thoughts 
from, you know, their thought 

388
00:22:55,800 --> 00:22:58,480
leaders in the industry and see 
how can we use this? 

389
00:22:58,480 --> 00:23:00,760
Can we use this to, to move 
things forward? 

390
00:23:00,760 --> 00:23:03,040
For sure. 
Is it? 

391
00:23:03,440 --> 00:23:05,520
Yeah. 
What what is the new tech or 

392
00:23:05,680 --> 00:23:08,080
what like what do you? 
What's this new sensor that 

393
00:23:08,080 --> 00:23:11,160
allows you to measure it? 
So it's called, it's called 

394
00:23:11,160 --> 00:23:14,920
sensor grip. 
Let me get let me get a picture 

395
00:23:14,920 --> 00:23:20,760
of him up here. 
OK, kind of show you guys what 

396
00:23:20,760 --> 00:23:25,120
it looks like here. 
Because the problem has always 

397
00:23:25,120 --> 00:23:27,120
been measuring this, right? 
Like that's always been the, 

398
00:23:27,160 --> 00:23:28,480
yeah, always been the issue, 
yeah. 

399
00:23:30,240 --> 00:23:33,200
So you can, you can kind of see 
a little bit here. 

400
00:23:34,640 --> 00:23:39,200
We use a, it's a grip Master 
leather wrap grip that goes over

401
00:23:39,200 --> 00:23:42,440
top of the sensors. 
So if you're familiar with how 

402
00:23:42,480 --> 00:23:45,920
those grips are kind of like a 
wind or a lizard skin grip, they

403
00:23:45,920 --> 00:23:49,600
have like a like a foam rubber 
core that goes on and then it's 

404
00:23:49,600 --> 00:23:52,120
wrapped on top. 
So the foam rubber core goes on,

405
00:23:52,520 --> 00:23:56,120
they wrap the the sensor wires 
around and they put the grip on 

406
00:23:56,120 --> 00:23:58,920
top. 
And then you have a wire that 

407
00:23:58,920 --> 00:24:00,720
comes out. 
In fact, the new one that they 

408
00:24:00,720 --> 00:24:04,560
just released, instead of the 
wire going all the way back to 

409
00:24:04,560 --> 00:24:07,760
the computer, it goes to a 
little thing on your hip and 

410
00:24:07,760 --> 00:24:10,440
then transmits via Bluetooth and
the wire is a lot thinner and 

411
00:24:10,440 --> 00:24:12,320
lighter. 
So, you know, they're making 

412
00:24:12,320 --> 00:24:14,320
some pretty good, pretty good 
advancements there. 

413
00:24:14,640 --> 00:24:16,400
And this is just the rest of the
tech we use. 

414
00:24:16,400 --> 00:24:19,440
So it was taking all four of 
these and then manually 

415
00:24:19,440 --> 00:24:24,080
collating the data. 
This is an idea of kind of sort 

416
00:24:24,080 --> 00:24:27,360
of what you can, you know, their
standard interface. 

417
00:24:27,360 --> 00:24:33,760
So it it links in with a webcam.
So for us, you know, the sensor 

418
00:24:33,760 --> 00:24:37,440
grip is very accurate in 
denoting impact time. 

419
00:24:37,480 --> 00:24:40,560
So we match the impact time on 
the sensor grip with the impact 

420
00:24:40,560 --> 00:24:44,600
time on the gears and use that 
as a time stamp to work back. 

421
00:24:45,040 --> 00:24:47,960
OK, so you can see here, it'll 
give you your, you know, it'll 

422
00:24:47,960 --> 00:24:51,360
give you your distribution at 
various points in the swing, top

423
00:24:51,360 --> 00:24:55,880
of the swing, lead arm, parallel
shaft, parallel impact. 

424
00:24:56,720 --> 00:24:59,280
You know, they're also now 
working on some calculations of 

425
00:24:59,280 --> 00:25:02,720
being able to extrapolate the 
net forces and applied to the 

426
00:25:02,720 --> 00:25:08,120
club as well. 
So it's, you know, like I said, 

427
00:25:08,120 --> 00:25:12,000
it's it's still not ready for 
the masses yet, but it's getting

428
00:25:12,000 --> 00:25:14,120
much closer to where I think 
you're going to start to see 

429
00:25:14,120 --> 00:25:17,120
this popping up in more golf 
academies for sure. 

430
00:25:18,280 --> 00:25:21,120
So when we're talking about the 
pressure applied, it was based 

431
00:25:21,120 --> 00:25:23,400
on your Max pressure that you 
could apply. 

432
00:25:24,200 --> 00:25:26,400
So what did you find? 
You mentioned that you did 

433
00:25:26,400 --> 00:25:28,960
measure just like strength with 
one of the, I forget the name of

434
00:25:28,960 --> 00:25:31,400
it, what you call it. 
Yeah, the dynamometer. 

435
00:25:31,520 --> 00:25:38,520
Yeah, what did the pros have? 
Also the greater like strength 

436
00:25:38,520 --> 00:25:42,200
overall as well. 
Yeah, they did. 

437
00:25:42,200 --> 00:25:46,040
So it was, let's pop this back 
up here. 

438
00:25:47,080 --> 00:25:50,760
So. 
So the professionals, whoopsie 

439
00:25:50,760 --> 00:25:54,960
professionals did have a higher 
overall grip strength. 

440
00:25:55,120 --> 00:25:59,360
Like I said, that was. 
The hook grip was closer, but 

441
00:25:59,360 --> 00:26:02,320
again, it was like I said, just 
total transparency. 

442
00:26:02,320 --> 00:26:04,960
It was a little skewed from a 
long drive competitor, you know,

443
00:26:04,960 --> 00:26:09,120
who happens to hook it, you 
know, And then as we get down, 

444
00:26:09,120 --> 00:26:10,760
the slicer was a little bit 
weaker. 

445
00:26:10,760 --> 00:26:12,800
Even though you don't see same 
age in here. 

446
00:26:13,440 --> 00:26:16,760
Obviously the age went up for 
the poor contact, which does 

447
00:26:16,760 --> 00:26:18,640
contribute to the grip strength 
going down. 

448
00:26:18,640 --> 00:26:24,040
But yeah, it's a pretty, in this
small study, pretty linear 

449
00:26:24,040 --> 00:26:26,600
relationship between group 
strength and handicap. 

450
00:26:26,600 --> 00:26:29,800
And you know, there is a lot of 
other, you know, studies, I know

451
00:26:29,800 --> 00:26:31,520
super speeds put some stuff out 
there. 

452
00:26:31,520 --> 00:26:35,160
They talk about the same type of
relationship they've seen for 

453
00:26:35,160 --> 00:26:38,080
group strength and club speed, 
which makes sense. 

454
00:26:38,080 --> 00:26:43,160
You know, I, you know, in the 
physical testing world, you 

455
00:26:43,160 --> 00:26:49,960
know, if I only had one test to 
do to try and gauge the overall,

456
00:26:49,960 --> 00:26:53,480
I guess strength, health, 
whatever of a person, I would go

457
00:26:53,480 --> 00:26:56,000
a grip strength because it just 
tied to so many other things. 

458
00:26:57,280 --> 00:27:01,000
Interesting. 
It is that 276, is that a good? 

459
00:27:01,000 --> 00:27:03,160
I'm not. 
I don't know these numbers very 

460
00:27:03,160 --> 00:27:04,120
well. 
Is that a good number? 

461
00:27:04,120 --> 00:27:06,240
Is it really strong? 
Is that just like an average 

462
00:27:06,240 --> 00:27:09,400
person or? 
Yeah, I mean, it's not bad. 

463
00:27:09,400 --> 00:27:14,360
I guess like, I guess for 
context, that's pretty much 

464
00:27:14,360 --> 00:27:18,280
where I'm at, OK, which I'm 
around £140 per hand. 

465
00:27:18,280 --> 00:27:23,960
I'm 45 year old former golfer 
that has been quite lazy and 

466
00:27:23,960 --> 00:27:27,440
sedentary the last couple years.
So, you know, it depends on 

467
00:27:27,440 --> 00:27:29,120
where you're starting out at as 
well. 

468
00:27:30,600 --> 00:27:34,440
When we're looking at, you know,
I would expect a competitive 

469
00:27:34,440 --> 00:27:39,320
long driver to be more in their 
350 to 360 LB ratio. 

470
00:27:40,640 --> 00:27:45,200
Yeah, yeah, OK. 
You know, that's kind of where 

471
00:27:45,200 --> 00:27:49,160
Micah lives, you know, a cruise 
control club and speed around 

472
00:27:49,160 --> 00:27:55,120
128 without training for golf. 
So you know, a lot of power 

473
00:27:55,120 --> 00:27:59,560
there. 
You know, I think within reason 

474
00:27:59,560 --> 00:28:05,480
for, again, for like 99% of the 
amateurs out there, I think more

475
00:28:05,480 --> 00:28:09,040
is better. 
Yeah, like I like I, I don't. 

476
00:28:09,960 --> 00:28:12,400
We're a long way from being so 
rigid with it. 

477
00:28:12,400 --> 00:28:15,720
It's set up and in the backswing
that it's going to impede the 

478
00:28:15,720 --> 00:28:18,120
golf swing. 
You know, I also start to think 

479
00:28:18,120 --> 00:28:22,880
about other stuff. 
I remember reading more things 

480
00:28:22,880 --> 00:28:27,360
from Doctor McKenzie about how I
believe he's proven that 

481
00:28:27,360 --> 00:28:31,720
increase in backswing speed 
results in more downswing speed.

482
00:28:31,720 --> 00:28:34,760
And I feel like, OK, well if I'm
going to swing it back faster, 

483
00:28:34,760 --> 00:28:36,480
the first thing I got to do is 
squeeze it tighter. 

484
00:28:36,480 --> 00:28:39,280
I got to activate these muscles 
up through the forearm, upper 

485
00:28:39,280 --> 00:28:41,720
arm, and even in the shoulder 
girdle and let's get everything 

486
00:28:41,720 --> 00:28:44,080
connected and working together. 
Yeah. 

487
00:28:44,200 --> 00:28:46,840
You know, instead of the 0 grip 
shankle, let me just take it 

488
00:28:46,840 --> 00:28:49,920
back with my wrist and I was 
going to start chasing the club 

489
00:28:49,920 --> 00:28:54,440
down with my body the whole way.
Yeah, what? 

490
00:28:55,120 --> 00:28:56,400
What do you? 
Think is the impact. 

491
00:28:56,400 --> 00:29:02,440
Of like grip size and grip like 
texture as well like on these 

492
00:29:02,440 --> 00:29:05,400
because because obviously they 
they couldn't use their grips, 

493
00:29:05,400 --> 00:29:07,480
right? 
So they're using the the sensor.

494
00:29:08,320 --> 00:29:13,120
So yeah, what is then size? 
Well, and you know, trying to do

495
00:29:13,120 --> 00:29:17,080
the best we could then charge 
was great. 

496
00:29:17,280 --> 00:29:25,440
They they put grips on two 
different flexes of shaft for 

497
00:29:25,440 --> 00:29:29,320
each driver, 7 iron so we're 
able to get them as close as 

498
00:29:29,320 --> 00:29:34,680
possible to their own shaft. 
We adjusted the lie loft of the 

499
00:29:34,680 --> 00:29:39,080
iron heads to match, you know, 
their current spec and we only 

500
00:29:39,080 --> 00:29:41,440
brought people in that were 
using a standard size grip. 

501
00:29:41,640 --> 00:29:46,760
So it does grip size matter. 
Absolutely can't tell you how. 

502
00:29:47,440 --> 00:29:49,360
I definitely think it'll be the 
next one. 

503
00:29:49,840 --> 00:29:55,240
Anecdotally, years and years and
years ago at the lab, we started

504
00:29:55,320 --> 00:29:58,840
taking long drivers and testing 
their grip strength at 

505
00:29:58,840 --> 00:30:02,120
different, you know, different 
diameters on the dynamometer. 

506
00:30:02,840 --> 00:30:05,640
And then wherever they had the 
highest grip strength, we would 

507
00:30:05,640 --> 00:30:07,960
do our best to build grips to 
match that size. 

508
00:30:08,520 --> 00:30:14,160
Oh, cool. 
I think in general, I think most

509
00:30:14,160 --> 00:30:20,400
people would perform better with
larger than standard grips as it

510
00:30:20,600 --> 00:30:23,480
as we get a little bigger than a
Golf Club than the standard Golf

511
00:30:23,480 --> 00:30:25,920
Club. 
Most of the people we test are 

512
00:30:25,920 --> 00:30:28,040
able to actually just put more 
force through it. 

513
00:30:29,720 --> 00:30:33,800
It you know, we're seeing, we're
seeing in the world longer 

514
00:30:33,800 --> 00:30:36,960
afterward. 
We're seeing pretty good 

515
00:30:36,960 --> 00:30:40,880
adoption rates into various 
sizes of jumbo mats, OK. 

516
00:30:40,880 --> 00:30:44,680
You know, we're seeing a little 
bit more of that on on the 

517
00:30:44,680 --> 00:30:48,720
professional tours as well. 
So here's here's what I 

518
00:30:48,720 --> 00:30:52,520
anecdotally know about larger 
grips is that like we've 

519
00:30:52,520 --> 00:30:54,320
traditionally been taught that 
they're going to go right 

520
00:30:54,320 --> 00:30:55,760
because you can't turn them over
right? 

521
00:30:55,760 --> 00:30:58,680
Like that's probably, I don't 
know, old, yeah, old, old 

522
00:30:58,720 --> 00:31:00,560
stereo. 
OK. 

523
00:31:00,800 --> 00:31:03,080
And then the second thing is 
that they. 

524
00:31:03,160 --> 00:31:05,160
Do that. 
Because they add weight. 

525
00:31:05,520 --> 00:31:08,920
So you just change the, the 
weight of the the club is why 

526
00:31:08,920 --> 00:31:10,800
they do that. 
So that's like that's what I 

527
00:31:10,800 --> 00:31:13,760
think about when I think about 
larger, larger grips a little 

528
00:31:13,760 --> 00:31:16,960
bit. 
Well, in the in the grip size 

529
00:31:16,960 --> 00:31:21,600
testing that we've done, I could
say a couple of things. 

530
00:31:21,600 --> 00:31:24,880
One was we actually found and we
weren't talking about pressures 

531
00:31:24,880 --> 00:31:26,480
before that technology was 
around. 

532
00:31:27,960 --> 00:31:31,000
We found that there was no 
correlation between hand hand 

533
00:31:31,000 --> 00:31:36,000
length and the grip size. 
That created maximum consistency

534
00:31:36,200 --> 00:31:41,760
directional control on average 
the thirty person amateur 

535
00:31:41,760 --> 00:31:43,720
population. 
And that was able to reduce 

536
00:31:43,720 --> 00:31:46,760
dispersion by 34% by just 
changing the grip size. 

537
00:31:47,640 --> 00:31:49,840
Wow. 
For some people it was going 

538
00:31:49,840 --> 00:31:52,920
smaller. 
Looking back now, for example, 

539
00:31:52,920 --> 00:31:56,320
we had one individual that had 
very, very, you know, the 

540
00:31:56,320 --> 00:31:58,680
largest hands in the study. 
He performed best with the 

541
00:31:58,680 --> 00:32:02,360
smallest grip, I think now total
guess. 

542
00:32:02,360 --> 00:32:05,520
But because it was so tiny, he 
had to squeeze so hard just to 

543
00:32:05,520 --> 00:32:08,200
keep it in there. 
If you stabilize the sweet spot,

544
00:32:08,200 --> 00:32:10,240
I had better connectivity may 
better contact. 

545
00:32:10,640 --> 00:32:14,480
Interesting. 
Yeah, the, the weight is a thing

546
00:32:14,480 --> 00:32:18,600
for sure because, you know, if 
you go to a heavier weight grip 

547
00:32:18,600 --> 00:32:22,880
and don't adjust swing weight 
properly, you're going to see, 

548
00:32:22,880 --> 00:32:25,080
as most people do, a reduced 
closure rate. 

549
00:32:25,280 --> 00:32:29,280
You know, you lose a little bit 
of wrist mobility and a 

550
00:32:29,280 --> 00:32:31,840
reduction in swing weight is 
kind of a double wing that can 

551
00:32:31,840 --> 00:32:36,280
create an excessive brightness. 
I got it. 

552
00:32:36,440 --> 00:32:39,000
Oh man, I got to order. 
I'm ordering a diameter right 

553
00:32:39,000 --> 00:32:42,440
now and that. 25 bucks on Amazon
man. 

554
00:32:42,920 --> 00:32:44,600
And we're swapping. 
We're going to do that. 

555
00:32:44,600 --> 00:32:46,960
I love that test. 
That seems so obvious. 

556
00:32:47,680 --> 00:32:53,440
Yeah, yeah, no, it's it. 
I mean, yeah, you just make 

557
00:32:53,440 --> 00:32:55,720
stuff up and try it. 
And as people get better, keep 

558
00:32:55,720 --> 00:32:58,120
doing it as they don't apologize
and do something else. 

559
00:32:58,400 --> 00:33:00,640
Are you going to do that again? 
We got to see that test come 

560
00:33:00,640 --> 00:33:01,480
back. 
We got to. 

561
00:33:02,160 --> 00:33:05,560
Yeah, no, no, no, no. 
The boys up at the lab are still

562
00:33:05,560 --> 00:33:06,760
doing it. 
Absolutely OK. 

563
00:33:07,680 --> 00:33:11,080
Oh yeah. 
So do you have a protocol then 

564
00:33:11,080 --> 00:33:13,400
is it like you'd go different 
lengths and you test the 

565
00:33:13,400 --> 00:33:17,800
strength and then you? 
Yeah, so different dynamometers 

566
00:33:17,800 --> 00:33:19,720
are a little different. 
You know, they have like this 

567
00:33:19,720 --> 00:33:24,600
little wheel where it kind of 
adjusts and scales the width of 

568
00:33:24,720 --> 00:33:28,160
the the gripping component. 
Just kind of eyeball it with 

569
00:33:28,160 --> 00:33:31,640
some golf grips there, OK, you 
know, so you can do it that way.

570
00:33:31,720 --> 00:33:34,320
You know, the other thing we've 
done in terms of our fitting 

571
00:33:34,320 --> 00:33:38,720
protocols is, you know, within 
our testing, we'll go with the 

572
00:33:38,720 --> 00:33:40,240
length and then we go with the 
weight. 

573
00:33:40,240 --> 00:33:44,240
And then we if we need to reduce
flex and then optimize the head 

574
00:33:44,240 --> 00:33:47,040
and if we still feel there's 
opportunity for improved 

575
00:33:47,040 --> 00:33:51,640
control, we actually have 5 
different size grips on the same

576
00:33:52,360 --> 00:33:55,160
driver fitting shaft and the 
same iron fitting shaft. 

577
00:33:55,160 --> 00:33:58,040
So we're able to do some testing
with the person, at least get 

578
00:33:58,040 --> 00:34:01,680
some objective data. 
OK, so I think that's one, you 

579
00:34:01,680 --> 00:34:05,760
know, other one if it's amateur 
golfers that are, you know, just

580
00:34:05,760 --> 00:34:08,560
out there going Oh my God, 
there's there might be something

581
00:34:08,600 --> 00:34:11,000
valuable here, but I don't know 
what to do because I got no one 

582
00:34:11,000 --> 00:34:13,880
to go to. 
You know, if you got a week or 

583
00:34:13,880 --> 00:34:18,400
whatever where you're not 
playing go like go throw a jumbo

584
00:34:18,400 --> 00:34:21,239
grip on your 9 iron in the mid 
South on your 8 and leave 

585
00:34:21,239 --> 00:34:23,800
everything else standard and 
just go dig it out the dirt at 

586
00:34:23,800 --> 00:34:27,760
the range and see what you see. 
I like it. 

587
00:34:27,840 --> 00:34:29,840
I like it. 
How do you, if someone's doing 

588
00:34:29,840 --> 00:34:33,360
that, how do they make sure it's
not a weight, a weight issue 

589
00:34:33,440 --> 00:34:38,520
that causes that well? 
You know, you could go online to

590
00:34:38,760 --> 00:34:40,760
the manufacturer website and 
check the weights. 

591
00:34:40,760 --> 00:34:44,000
So like just on the weight. 
Then I think this is like this 

592
00:34:44,000 --> 00:34:50,080
will be my my PSA for the day. 
OK, white grips are heavy. 

593
00:34:50,800 --> 00:34:54,920
So if you if you wear like the 
golf pride tour wrap and then 

594
00:34:54,920 --> 00:34:57,480
the white golf pride tour wrap, 
it's like 10 grams heavier. 

595
00:34:57,480 --> 00:34:58,960
It makes a big difference in 
swing weight. 

596
00:34:58,960 --> 00:35:01,160
I guess I have to put so much 
white dye in the rubber. 

597
00:35:01,520 --> 00:35:05,640
It makes it heavier. 
So they'll go white and then, 

598
00:35:06,760 --> 00:35:08,600
you know, Yeah. 
Check the manufacturer website 

599
00:35:08,600 --> 00:35:10,960
at most places. 
Like there's Redwood Watch just 

600
00:35:10,960 --> 00:35:12,600
down the street from me. 
Yeah. 

601
00:35:12,600 --> 00:35:14,040
And they got a little club 
building set up. 

602
00:35:14,040 --> 00:35:17,040
They got a gram white scale. 
So, you know, just ask the guy 

603
00:35:17,040 --> 00:35:19,360
to weigh the grips for you so 
you can see what you're dealing 

604
00:35:19,360 --> 00:35:23,080
with, you know, and ideally if 
they have a swing white scale 

605
00:35:23,080 --> 00:35:25,920
and maybe they need to slap a 
piece of lead tape on the head 

606
00:35:25,920 --> 00:35:27,680
to keep the overall balance the 
same. 

607
00:35:28,560 --> 00:35:32,000
OK, got it on it. 
I'm on it here. 

608
00:35:32,000 --> 00:35:37,120
I'm going to share my screen and
so you can so dynamometer I'm I 

609
00:35:37,120 --> 00:35:41,400
need to order right now. 
So we're just, we're just 

610
00:35:41,400 --> 00:35:44,120
throwing one of these on there. 
Yeah, yeah. 

611
00:35:44,120 --> 00:35:46,800
Like those two on the left are 
kind of our normal ones. 

612
00:35:46,800 --> 00:35:51,800
If you want to go all out, we do
for all of our research stuff we

613
00:35:51,800 --> 00:35:56,600
do use that one on the right. 
It's 300 bucks not not necessary

614
00:35:56,600 --> 00:35:58,760
for the at home user or the golf
Academy. 

615
00:35:59,120 --> 00:36:00,080
OK. 
Got it. 

616
00:36:00,240 --> 00:36:02,280
All right, we'll grab. 
We'll, I'm going to grab one of 

617
00:36:02,280 --> 00:36:03,520
those. 
I'm not. 

618
00:36:03,520 --> 00:36:07,480
Man. 
OK, so we, we've got everyone 

619
00:36:07,480 --> 00:36:12,440
needs to grip it more at setup 
that is for sure. 

620
00:36:13,120 --> 00:36:17,120
And then maybe depending on your
your Swing type, there could be 

621
00:36:17,120 --> 00:36:20,640
some some interventions you 
could try to help make some 

622
00:36:20,640 --> 00:36:24,040
changes. 
And it's like the most general 

623
00:36:24,360 --> 00:36:29,000
blanket statement possible. 
You know that we're pretend 

624
00:36:29,000 --> 00:36:32,080
we're back in Scotland like a 
few years ago and we're you 

625
00:36:32,080 --> 00:36:34,200
know, we're out at a pub having 
to be going, oh, I don't know 

626
00:36:34,200 --> 00:36:36,480
about this golf thing. 
You just tell me how I squeeze 

627
00:36:36,480 --> 00:36:41,000
it like, oh boy, well, squeeze 
it pretty tight, like a like a 

628
00:36:41,000 --> 00:36:44,960
good firm handshake. 
And I start try and feel that 

629
00:36:44,960 --> 00:36:46,680
stay constant through the 
backswing. 

630
00:36:46,680 --> 00:36:49,360
Try not to try not to feel an 
increase. 

631
00:36:49,960 --> 00:36:53,120
OK. 
And then in transition when 

632
00:36:53,120 --> 00:36:58,840
you're changing direction, feel 
like it's, you know, it lightens

633
00:36:58,840 --> 00:37:03,440
up if anything. 
So it's like, start strong, stay

634
00:37:03,440 --> 00:37:07,920
constant, relax when I change 
direction, and then hey, from 

635
00:37:07,920 --> 00:37:09,440
there whatever else happens, 
happens. 

636
00:37:09,960 --> 00:37:12,040
Sergio had the regroup, right? 
He always did. 

637
00:37:12,040 --> 00:37:14,000
Or who did? 
Who does the regroup at like? 

638
00:37:14,000 --> 00:37:15,760
Transcript. 
I mean he would regroup it like 

639
00:37:15,760 --> 00:37:19,160
100 times at setup, you know, in
transition. 

640
00:37:19,720 --> 00:37:21,400
Didn't he do it in transition? 
Where he kind? 

641
00:37:21,400 --> 00:37:22,840
Of he might have. 
You could see. 

642
00:37:22,840 --> 00:37:28,160
Yeah, I think, yeah. 
Yeah, when he get I've seen a 

643
00:37:28,160 --> 00:37:31,400
ton of images of like when BJ 
gets contact and is 

644
00:37:31,400 --> 00:37:33,360
right-handed. 
So I plan off the club. 

645
00:37:33,520 --> 00:37:36,960
Yeah, see that a lot in baseball
too. 

646
00:37:37,840 --> 00:37:41,000
Yeah, it's it's interesting, 
man. 

647
00:37:41,200 --> 00:37:44,480
Like, I think we're just 
scratching the surface when you 

648
00:37:44,480 --> 00:37:48,160
know it's going to be 3 to five 
more years before we really have

649
00:37:48,160 --> 00:37:50,720
deep, valuable insights. 
Yep, Yep. 

650
00:37:52,200 --> 00:37:53,720
Sweet. 
All right. 

651
00:37:54,040 --> 00:37:55,360
Thanks for sharing, man. 
Yeah.
