00:00:00,000 --> 00:00:03,000
In this video, we're going to look at grip strength.

00:00:03,000 --> 00:00:07,000
Now in a number of these videos, I talk about the concept of grip strength.

00:00:07,000 --> 00:00:09,000
So I thought it would be helpful for us to get on the same page.

00:00:09,000 --> 00:00:12,000
So let's define it.

00:00:12,000 --> 00:00:16,000
Grip strength is really just a term that golf instructors have used to define how you're

00:00:16,000 --> 00:00:18,000
holding on to the club.

00:00:18,000 --> 00:00:23,000
Now with typical video analysis, they're usually using a reference frame.

00:00:23,000 --> 00:00:28,000
So if I'm looking from a face on point of view, what they'll usually look at is where

00:00:29,000 --> 00:00:31,000
these V's pointed like so.

00:00:31,000 --> 00:00:35,000
But for me, that's a little bit vague.

00:00:35,000 --> 00:00:40,000
So with 3D motion analysis, I've noticed certain correlations with what you see on video

00:00:40,000 --> 00:00:42,000
and what you see on 3D.

00:00:42,000 --> 00:00:48,000
And so here's how we hear so I and us here at a golf smart academy look at grip strength.

00:00:48,000 --> 00:00:55,000
So we're going to look at flexion extension of the wrist as the primary determinant of grip strength.

00:00:55,000 --> 00:01:00,000
Now grip strength is commonly referred to as either being neutral, which would be pointing

00:01:00,000 --> 00:01:04,000
somewhere right around this right shoulder, strong pointing over here to the right of the

00:01:04,000 --> 00:01:06,000
right shoulder.

00:01:06,000 --> 00:01:07,000
So that would be strong.

00:01:07,000 --> 00:01:08,000
That would be kind of neutral.

00:01:08,000 --> 00:01:11,000
And then pointing more up at my chin would be weak.

00:01:11,000 --> 00:01:15,000
So let's look at the flexion extension component to this.

00:01:15,000 --> 00:01:21,000
A neutral grip on 3D is roughly going to be about 25 degrees of extension like so.

00:01:21,000 --> 00:01:27,000
So if I take this 25 degrees and put it on the grip just like so as you've been practicing

00:01:27,000 --> 00:01:32,000
in kind of the grip section, you'll see that this points roughly over to my shoulder

00:01:32,000 --> 00:01:34,000
if it's kind of in the middle of my body.

00:01:34,000 --> 00:01:39,000
Obviously if I took this and stood with it here, it would be very hard for me to say

00:01:39,000 --> 00:01:44,000
where that V is pointing because of kind of the unorthodox position.

00:01:44,000 --> 00:01:48,000
If we're looking at the trail wrist, then neutral is going to be pretty much straight

00:01:48,000 --> 00:01:51,000
or I'd say plus or minus 5 degrees.

00:01:51,000 --> 00:01:55,000
So whether it's just there, just there, that's pretty neutral.

00:01:55,000 --> 00:02:00,000
So if I take my grip, which I consider fairly neutral from looking at 3D and video, so if

00:02:00,000 --> 00:02:03,000
I take my grip, kind of look something like that.

00:02:03,000 --> 00:02:09,000
So I've got about 25 degrees of cup in this lead wrist and I've got this trail wrist pretty

00:02:09,000 --> 00:02:10,000
much straight.

00:02:10,000 --> 00:02:15,000
Now one of the other factors that a lot of instructors talk about is looking at how much

00:02:15,000 --> 00:02:22,000
these forums are kind of rotated on the grip because we're essentially taking the cylinder

00:02:22,000 --> 00:02:25,000
of the grip and we're positioning our hands on it.

00:02:25,000 --> 00:02:31,000
So one way to think of a strong grip is my hands are turned more underneath or my hands

00:02:31,000 --> 00:02:36,000
are turned more to the right for a right hand and golfer and a weak grip would be my hands

00:02:36,000 --> 00:02:42,000
are turned more to the left and a neutral grip would be just slightly to the right.

00:02:42,000 --> 00:02:47,000
I'm going to give you a little bit more, let me first, the reason I don't like that is

00:02:47,000 --> 00:02:54,000
because if you look at 3D of just the forums, what tends to happen is just because a person

00:02:54,000 --> 00:03:00,000
sets up with this grip a little bit stronger doesn't really impact too much how the arms

00:03:00,000 --> 00:03:03,000
are going to work in the downswing.

00:03:03,000 --> 00:03:06,000
Basically that whole concept is built around this premise.

00:03:06,000 --> 00:03:10,000
If you look from a face on camera view, a lot of golfers will come back with this looking

00:03:10,000 --> 00:03:14,000
like it's pointing in the general direction of the target.

00:03:14,000 --> 00:03:19,000
Now the problem is since I'm able to isolate this section, I can tell you that where you

00:03:19,000 --> 00:03:24,000
set up most golfers are going to be slightly more pronated when they make contact with

00:03:24,000 --> 00:03:25,000
the golf wall.

00:03:25,000 --> 00:03:29,000
Tour golfers are going to be typically around 20 degrees more pronated like so.

00:03:29,000 --> 00:03:34,000
So the problem is the assumption is if I start with it more like this than when it comes

00:03:34,000 --> 00:03:36,000
back, that's going to close the club face.

00:03:36,000 --> 00:03:41,000
But what usually happens is if I start with it more straighter like this, then I'm

00:03:41,000 --> 00:03:47,000
going to have more side bend, more rotation, more shoulder external rotation.

00:03:47,000 --> 00:03:53,000
So I have all these other compensating or contributing movements and it's not just that

00:03:53,000 --> 00:03:56,000
my forums all come back to the same location.

00:03:56,000 --> 00:04:00,000
So we're going to scratch that and we're just going to say grip strength is going to be

00:04:00,000 --> 00:04:06,000
about 20 or extension of the trail or lead wrist and flexion of the trail wrist.

00:04:06,000 --> 00:04:09,000
The trail is going to be about 25 and 0.

00:04:09,000 --> 00:04:15,000
If it's I've seen strong grips up around 45, 48 and I've seen weak grips around 0.

00:04:15,000 --> 00:04:21,000
Over here I've seen kind of weak grips in the minus 20 and strong grips in the positive

00:04:21,000 --> 00:04:23,000
10 positive 15.

00:04:23,000 --> 00:04:27,000
But in general we're going to be about 25 and neutral.

00:04:27,000 --> 00:04:32,000
Now let's put those hand positions as they relate to the grip.

00:04:32,000 --> 00:04:34,000
So most grips and I'll give a little close up here.

00:04:34,000 --> 00:04:38,000
So most grips are going to have something that indicates kind of the middle of the club

00:04:38,000 --> 00:04:46,000
face and if I angle this down you'll see that roughly coincides with the leading edge or

00:04:46,000 --> 00:04:48,000
the club face position.

00:04:48,000 --> 00:04:52,000
So it's pretty easy to see where dead center would be on the club.

00:04:52,000 --> 00:04:56,000
If I was to extend the wrist, so I'm going to go through the grip process.

00:04:56,000 --> 00:05:01,000
So I'm going to extend the wrist slightly and now when I put my hand on the grip, that's

00:05:01,000 --> 00:05:06,000
going to put it slightly to the right of center.

00:05:06,000 --> 00:05:07,000
You can see there's the center line.

00:05:07,000 --> 00:05:10,000
It's just going to put it slightly to the right of center.

00:05:10,000 --> 00:05:13,000
Then I make sure it's in the fingers like so.

00:05:13,000 --> 00:05:18,000
When I slide this hand back, that wrist is pretty much a neutral and I've established kind

00:05:18,000 --> 00:05:20,000
of my good neutral grip.

00:05:20,000 --> 00:05:25,000
So when we go forward and you look at the rest of these videos, you're going to hear me say

00:05:25,000 --> 00:05:26,000
grip strength.

00:05:26,000 --> 00:05:29,000
Know that I'm not talking about how tightly you're squeezing the club.

00:05:29,000 --> 00:05:33,000
I'm talking about how your hands are positioned on the club and that's going to have

00:05:33,000 --> 00:05:37,000
a direct impact on how you're going to control the club face and what you're going to do

00:05:37,000 --> 00:05:38,000
with the rest of the body.

00:05:38,000 --> 00:05:41,000
So pay attention to your grip strength.

00:05:41,000 --> 00:05:45,000
It's definitely one of the things that I like to adjust any time we're trying to adjust

00:05:45,000 --> 00:05:47,000
the club face to the path.

00:05:47,000 --> 00:05:50,000
So it's a useful tool to get sensitive to and know how it works.
