00:00:00.000 --> 00:00:03.280
In this video, we're going to look at grip strength.

2
00:00:03.280 --> 00:00:07.440
Now, in a number of these videos, I talk about the concept of grip strength, so

3
00:00:07.440 --> 00:00:07.840
I thought

4
00:00:07.840 --> 00:00:12.120
it would be helpful for us to get on the same page, so let's define it.

5
00:00:12.120 --> 00:00:16.340
Grip strength is really just the term the golf instructors have used to define

6
00:00:16.340 --> 00:00:16.840
how you're

7
00:00:16.840 --> 00:00:18.480
holding onto the club.

8
00:00:18.480 --> 00:00:24.000
Now with typical video analysis, they're usually using a reference frame, so if

9
00:00:24.000 --> 00:00:24.680
I'm looking

10
00:00:24.680 --> 00:00:29.920
from a face on point of view, what they'll usually look at is where are these V

11
00:00:29.920 --> 00:00:30.760
's pointed

12
00:00:30.760 --> 00:00:31.760
like so.

13
00:00:31.760 --> 00:00:35.080
But for me, that's a little bit vague.

14
00:00:35.080 --> 00:00:40.020
So with 3D motion analysis, I've noticed certain correlations with what you see

15
00:00:40.020 --> 00:00:40.840
on video and

16
00:00:40.840 --> 00:00:46.400
what you see on 3D, and so here's how we, here's how I, and us here at Golf

17
00:00:46.400 --> 00:00:47.520
Smart Academy,

18
00:00:47.520 --> 00:00:48.840
look at grip strength.

19
00:00:48.840 --> 00:00:53.050
So we're going to look at flexion extension of the wrist as the primary

20
00:00:53.050 --> 00:00:54.040
determinant of

21
00:00:54.040 --> 00:00:55.040
grip strength.

22
00:00:55.040 --> 00:00:59.870
Now, grip strength is commonly referred to as either being neutral, which would

23
00:00:59.870 --> 00:01:00.400
be pointing

24
00:01:00.400 --> 00:01:03.730
somewhere right around this right shoulder, strong pointing over here to the

25
00:01:03.730 --> 00:01:04.080
right of

26
00:01:04.080 --> 00:01:08.540
the right shoulder, so that would be strong, that would be kind of neutral, and

27
00:01:08.540 --> 00:01:09.320
then pointing

28
00:01:09.320 --> 00:01:11.800
more up at my chin would be weak.

29
00:01:11.800 --> 00:01:15.600
So let's look at the flexion extension component to this.

30
00:01:15.600 --> 00:01:20.960
A neutral grip on 3D is roughly going to be about 25 degrees of extension like

31
00:01:20.960 --> 00:01:21.480
so.

32
00:01:21.480 --> 00:01:26.680
So if I take this 25 degrees and put it on the grip just like so as you've been

33
00:01:26.680 --> 00:01:27.520
practicing

34
00:01:27.520 --> 00:01:31.860
in kind of the grip section, you'll see that this points roughly over to my

35
00:01:31.860 --> 00:01:32.640
shoulder if

36
00:01:32.640 --> 00:01:34.440
it's kind of in the middle of my body.

37
00:01:34.440 --> 00:01:38.920
Obviously, if I took this and stood with it here, it would be very hard for me

38
00:01:38.920 --> 00:01:39.720
to say

39
00:01:39.720 --> 00:01:43.560
where that V is pointing because of kind of the unorthodox position.

40
00:01:43.560 --> 00:01:48.210
If we're looking at the trail wrist, then neutral is going to be pretty much

41
00:01:48.210 --> 00:01:48.880
straight

42
00:01:48.880 --> 00:01:51.640
or I'd say plus or minus 5 degrees.

43
00:01:51.640 --> 00:01:55.200
So whether it's just there, just there, that's pretty neutral.

44
00:01:55.200 --> 00:01:59.770
So if I take my grip, which I consider fairly neutral from looking at 3D and

45
00:01:59.770 --> 00:02:00.640
video, so if

46
00:02:00.640 --> 00:02:04.940
I take my grip, kind of look something like that, so I've got about 25 degrees

47
00:02:04.940 --> 00:02:05.340
of cup

48
00:02:05.340 --> 00:02:10.560
in this lead wrist and I've got this trail wrist pretty much straight.

49
00:02:10.560 --> 00:02:15.070
Now, one of the other factors that a lot of instructors talk about is looking

50
00:02:15.070 --> 00:02:15.520
at how

51
00:02:15.520 --> 00:02:20.680
much these forms are kind of rotated on the grip because we're essentially

52
00:02:20.680 --> 00:02:21.440
taking the

53
00:02:21.440 --> 00:02:25.200
cylinder of the grip and we're positioning our hands on it.

54
00:02:25.200 --> 00:02:31.430
So one way to think of a strong grip is my hands are turned more underneath or

55
00:02:31.430 --> 00:02:32.000
my hands

56
00:02:32.000 --> 00:02:35.780
are turned more to the right for a right-handing golfer and a weak grip would

57
00:02:35.780 --> 00:02:36.440
be my hands are

58
00:02:36.440 --> 00:02:42.160
turned more to the left and a neutral grip would be just slightly to the right.

59
00:02:42.160 --> 00:02:47.000
I'm going to give you a little bit more, let me first, the reason I don't like

60
00:02:47.000 --> 00:02:47.800
that is because

61
00:02:47.800 --> 00:02:54.030
if you look at 3D of just the forearms, what tends to happen is just because a

62
00:02:54.030 --> 00:02:54.960
person sets

63
00:02:54.960 --> 00:02:59.900
up with this grip a little bit stronger doesn't really impact too much how the

64
00:02:59.900 --> 00:03:00.760
arms are going

65
00:03:00.760 --> 00:03:03.320
to work in the downswing.

66
00:03:03.320 --> 00:03:06.280
Basically that whole concept is built around this premise.

67
00:03:06.280 --> 00:03:10.010
If you look from a face-on camera view, a lot of golfers will come back with

68
00:03:10.010 --> 00:03:10.960
this looking

69
00:03:10.960 --> 00:03:13.960
like it's pointing in the general direction of the target.

70
00:03:13.960 --> 00:03:18.470
Now the problem is since I'm able to isolate this section, I can tell you that

71
00:03:18.470 --> 00:03:19.140
where you

72
00:03:19.140 --> 00:03:23.940
set up most golfers are going to be slightly more pronated when they make

73
00:03:23.940 --> 00:03:24.880
contact with

74
00:03:24.880 --> 00:03:25.880
the golf ball.

75
00:03:25.880 --> 00:03:29.920
Tour golfers are going to be typically around 20 degrees more pronated like so.

76
00:03:29.920 --> 00:03:34.150
So the problem is the assumption is if I start with it more like this than when

77
00:03:34.150 --> 00:03:34.600
it comes

78
00:03:34.600 --> 00:03:36.920
back that's going to close the club face.

79
00:03:36.920 --> 00:03:40.650
But what usually happens is if I start with it more straighter like this, then

80
00:03:40.650 --> 00:03:41.200
I'm going

81
00:03:41.200 --> 00:03:47.240
to have more side bend, more rotation, more shoulder external rotation.

82
00:03:47.240 --> 00:03:52.250
So I have all these other kind of compensating or contributing movements and it

83
00:03:52.250 --> 00:03:53.000
's not just

84
00:03:53.000 --> 00:03:56.080
that my forearms all come back to the same location.

85
00:03:56.080 --> 00:03:59.400
So we're going to scratch that and we're just going to say grip strength is

86
00:03:59.400 --> 00:03:59.520
going to

87
00:03:59.520 --> 00:04:06.120
be about 20 or extension of the lead wrist and flexion of the trail wrist.

88
00:04:06.120 --> 00:04:09.760
Neutral is going to be about 25 and 0.

89
00:04:09.760 --> 00:04:15.600
I've seen strong grips up around 45, 48 and I've seen weak grips around 0.

90
00:04:15.600 --> 00:04:20.880
Over here I've seen kind of weak grips in the minus 20 and strong grips in the

91
00:04:20.880 --> 00:04:21.640
positive

92
00:04:21.640 --> 00:04:23.360
10, positive 15.

93
00:04:23.360 --> 00:04:27.040
But in general we're going to be about 25 and neutral.

94
00:04:27.040 --> 00:04:31.960
Now let's put those hand positions as they relate to the grip.

95
00:04:31.960 --> 00:04:34.960
So most grips and I'll give a little close up here.

96
00:04:34.960 --> 00:04:38.340
So most grips are going to have something that indicates kind of the middle of

97
00:04:38.340 --> 00:04:39.560
the clubface.

98
00:04:39.560 --> 00:04:45.070
And if I angle this down you'll see that that roughly coincides with the

99
00:04:45.070 --> 00:04:46.200
leading edge

100
00:04:46.200 --> 00:04:48.160
or the clubface position.

101
00:04:48.160 --> 00:04:52.480
So it's pretty easy to see where dead center would be on the club.

102
00:04:52.480 --> 00:04:56.400
If I was to extend the wrist, so I'm going to go through the grip process, so I

103
00:04:56.400 --> 00:04:56.760
'm going

104
00:04:56.760 --> 00:05:01.700
to extend the wrist slightly and now when I put my hand on the grip that's

105
00:05:01.700 --> 00:05:02.360
going to

106
00:05:02.360 --> 00:05:06.280
put it slightly to the right of center.

107
00:05:06.280 --> 00:05:09.020
You can see there's the center line, it's just going to put it slightly to the

108
00:05:09.020 --> 00:05:09.440
right

109
00:05:09.440 --> 00:05:10.440
of center.

110
00:05:10.440 --> 00:05:13.120
Then I make sure it's in the fingers like so.

111
00:05:13.120 --> 00:05:17.110
When I slide this hand back that wrist is pretty much neutral and I've

112
00:05:17.110 --> 00:05:18.200
established kind

113
00:05:18.200 --> 00:05:20.480
of my good neutral grip.

114
00:05:20.480 --> 00:05:24.640
So when we go forward and you look at the rest of these videos you're going to

115
00:05:24.640 --> 00:05:25.040
hear

116
00:05:25.040 --> 00:05:26.120
me say grip strength.

117
00:05:26.120 --> 00:05:29.360
Know that I'm not talking about how tightly you're squeezing the club.

118
00:05:29.360 --> 00:05:33.410
I'm talking about how your hands are positioned on the club and that's going to

119
00:05:33.410 --> 00:05:34.200
have a direct

120
00:05:34.200 --> 00:05:37.530
impact on how you're going to control the clubface and what you're going to do

121
00:05:37.530 --> 00:05:37.760
with

122
00:05:37.760 --> 00:05:38.880
the rest of the body.

123
00:05:38.880 --> 00:05:41.400
So pay attention to your grip strength.

124
00:05:41.400 --> 00:05:44.730
It's definitely one of the things that I like to adjust any time we're trying

125
00:05:44.730 --> 00:05:45.280
to adjust

126
00:05:45.280 --> 00:05:47.440
the clubface to the path.

127
00:05:47.440 --> 00:05:50.440
So it's a useful tool to get sensitive to and know how it works.
