00:00:00,000 --> 00:00:05,000
This call smart insight is seeing clubface rotation with 2D video.

00:00:05,000 --> 00:00:12,000
So I had a member ask, you know, how can you tell if you're rotating the club closed

00:00:12,000 --> 00:00:17,000
or if you're doing it more with the in-plane movement or arm straightening?

00:00:17,000 --> 00:00:19,000
Because it is a little bit tricky to see.

00:00:19,000 --> 00:00:24,000
So what I'm going to show you here is how you can use down the line video to identify

00:00:24,000 --> 00:00:29,000
whether you're doing it more with shaft rotation or whether you're doing it more with

00:00:29,000 --> 00:00:34,000
the in-plane club movement or arm straightening.

00:00:34,000 --> 00:00:39,000
From the down the line camera, the really telling phase is going to be just below waist

00:00:39,000 --> 00:00:42,000
height or just below shaft parallel.

00:00:42,000 --> 00:00:47,000
So what you'll tend to see is from here we have to look in 3D space.

00:00:47,000 --> 00:00:51,000
So we're going to have to use face on as well as down the line to see what's going on.

00:00:51,000 --> 00:00:58,000
You'll see that there the clubface rotated towards the ball, but if I did that facing

00:00:58,000 --> 00:01:04,000
the camera, that is happening more from the in-plane movement or more from my arm

00:01:04,000 --> 00:01:10,000
straightening, whether my wrist or my triceps or elbows or whatever.

00:01:10,000 --> 00:01:16,000
So if you're looking from face on and you see the club going like this where the hands

00:01:16,000 --> 00:01:21,000
stay more towards that right side of the body as the club passes and you're looking

00:01:21,000 --> 00:01:25,000
from down the line and it looks like the clubface is rotating.

00:01:25,000 --> 00:01:29,000
You know that that's happening more from the in-plane movement.

00:01:29,000 --> 00:01:36,000
If you see that roughly same amount of club rotation through there, but then from face

00:01:36,000 --> 00:01:43,000
on you see the grip working more across the body as that's happening than you know that

00:01:43,000 --> 00:01:46,000
it's happening more from that shaft rotation.

00:01:46,000 --> 00:01:52,000
So we'll look at a few examples so that we can kind of start training our mind to see

00:01:52,000 --> 00:01:57,000
what we're trying to look at and hopefully you'll be able to see the amount of shaft

00:01:57,000 --> 00:02:01,000
rotation a little bit easier, but we're going to look at it during that phase I just

00:02:01,000 --> 00:02:05,000
showed you as well as what's happening just after the golf ball.

00:02:05,000 --> 00:02:10,000
When I'm looking at the video, this is the graph that I'm trying to imagine in my head.

00:02:10,000 --> 00:02:15,000
It's called axial velocity and it's looking at the rotational speed of the clubhead

00:02:15,000 --> 00:02:16,000
compared to the shaft.

00:02:16,000 --> 00:02:21,000
So when it goes negative the clubface is rotating open and when it goes positive it is

00:02:22,000 --> 00:02:22,000
rotating closed.

00:02:22,000 --> 00:02:27,000
So here's a golfer that has more of a gradual closing in the clubface.

00:02:27,000 --> 00:02:31,000
You can see that it starts to get positive actually before he changes direction and just

00:02:31,000 --> 00:02:35,000
kind of continues on a gradual slope.

00:02:35,000 --> 00:02:41,000
We can contrast that with this example would be a golfer who has more of a rapid closing

00:02:41,000 --> 00:02:44,000
later or uses more of the in-plane movement.

00:02:44,000 --> 00:02:48,000
So here you can see the club is opening and then as he changes direction you can see

00:02:48,000 --> 00:02:50,000
that it remains opening.

00:02:50,000 --> 00:02:57,000
It's still negative until about shaft 45 or so or closer to shaft parallel and then you'll

00:02:57,000 --> 00:02:59,000
see it closes very quickly.

00:02:59,000 --> 00:03:02,000
We can also correlate this graph with the straightening of the arm.

00:03:02,000 --> 00:03:05,000
But not everyone has access to this graph.

00:03:05,000 --> 00:03:09,000
So let's take a look at video and see how we can imagine it in 3D space.

00:03:09,000 --> 00:03:13,000
Alright, we'll look at a couple of different examples of each style.

00:03:14,000 --> 00:03:19,000
Takes a little bit of practice getting to be able to see it and you can't see it as

00:03:19,000 --> 00:03:22,000
accurately as you would on the graph.

00:03:22,000 --> 00:03:24,000
But we just want to see the general pattern.

00:03:24,000 --> 00:03:30,000
So what you're looking for is the clubface angle relative to the shaft.

00:03:30,000 --> 00:03:40,000
So if I were to move through these frames and let's just indicate where the clubhead

00:03:40,000 --> 00:03:43,000
is.

00:03:43,000 --> 00:03:49,000
It gives us just a rough line of travel that the club is going on.

00:03:49,000 --> 00:03:54,000
Now you can see up at the top there the club is pointing straight up and down and then

00:03:54,000 --> 00:04:00,000
at this point you can see that it is pointing closer to perpendicular to the swing

00:04:00,000 --> 00:04:06,000
plane and then down here you can see that it's pointing more or less at the ball.

00:04:06,000 --> 00:04:12,000
But when you're looking at these two you can see the amount of rotation kind of through

00:04:12,000 --> 00:04:14,000
this window or through this phase.

00:04:14,000 --> 00:04:19,000
Now that you know what you're looking for you can kind of start to see it actually happen

00:04:19,000 --> 00:04:24,000
in through there you can actually start to see the club rotating around its axis through

00:04:24,000 --> 00:04:25,000
there.

00:04:25,000 --> 00:04:33,000
Now what you'll you want to confirm it by looking at the face on video and comparing it

00:04:33,000 --> 00:04:36,000
to the timing of the straightening of that right arm.

00:04:36,000 --> 00:04:40,000
So we know that we were looking at the one on the left and we saw that it was rotating

00:04:40,000 --> 00:04:46,000
through this phase and then we'll see that his arm doesn't really straighten while it's

00:04:46,000 --> 00:04:51,000
going through that phase and there's not a lot of club passing the hands.

00:04:51,000 --> 00:04:55,000
When we look at a few examples of the club passing the hands we'll see one other indicator

00:04:55,000 --> 00:05:00,000
that you can see from the face on view that will give you a key or a clue to see if it's

00:05:00,000 --> 00:05:05,000
more of the shaft rotation or in plane shaft movement.

00:05:05,000 --> 00:05:11,000
So we want to train ourselves to be able to see it without having to draw the line and

00:05:11,000 --> 00:05:15,000
here we've got I wanted to use examples with kind of different grip styles so Dustin obviously

00:05:15,000 --> 00:05:20,000
has a stronger grip and Jordan's probably more neutral even to the weak side.

00:05:20,000 --> 00:05:26,000
You can see up here that the club is over the club head and club face is roughly in line

00:05:26,000 --> 00:05:32,000
with the direction it's traveling and you can see that by the time he gets to here it's

00:05:32,000 --> 00:05:38,000
now starting to rotate in point towards the golf ball so you can see actually right in

00:05:38,000 --> 00:05:43,000
through there is where the club face is starting to rotate and then you see the effect

00:05:43,000 --> 00:05:46,000
of it and it really rotates through that phase there.

00:05:46,000 --> 00:05:54,000
Now let's double check from the face on view and confirm that it is happening not with

00:05:54,000 --> 00:06:00,000
the straightening of the arm so we can see that through there and the other check that

00:06:00,000 --> 00:06:04,000
you'll be able to see is kind of the width on the way through.

00:06:04,000 --> 00:06:10,000
If you tend to use more of the in plane shaft movement you won't have shaft length so

00:06:10,000 --> 00:06:15,000
this particular clip misses impact but you can tell by the shaft being pretty vertical

00:06:15,000 --> 00:06:22,000
out in front of his lead leg that he had some shaft length in impact which would be virtually

00:06:22,000 --> 00:06:27,000
impossible with just the in plane movement and what you'll tend to see is on the way through

00:06:27,000 --> 00:06:33,000
you'll tend to see the club leaving the ground very quickly so you won't have a really

00:06:33,000 --> 00:06:39,000
long kind of wide flat bottom of this wing you'll tend to see the club bottom out even

00:06:39,000 --> 00:06:43,000
before the golf ball or be more of a picker style with the irons and you'll see the club

00:06:43,000 --> 00:06:49,000
come up pretty quickly. So let's take a look at a couple examples of golfers who don't

00:06:49,000 --> 00:06:54,000
have as much of this face rotation. Before we look at a couple amateur examples I wanted to

00:06:54,000 --> 00:07:01,000
show a elite level golfer who uses more or less of the face rotation model. So here you

00:07:01,000 --> 00:07:07,000
can see film Nicholson and you have the the clear vision of the club up against his body

00:07:07,000 --> 00:07:12,000
and you can see that through this space now that you know what to look for you can see

00:07:12,000 --> 00:07:20,000
there's not a lot of rotation it's pretty much close to the same angle compared to the path

00:07:20,000 --> 00:07:26,000
of the club through that space it closes a little bit but we want to confirm that that's

00:07:26,000 --> 00:07:32,000
happening more from the rotation or the arm extension we can look at it from the face on view

00:07:32,000 --> 00:07:37,000
we we saw that it was starting to rotate kind of around this zone here and you'll see that

00:07:37,000 --> 00:07:43,000
that left arm his trail arm is straightening through that phase which tends to give a little

00:07:43,000 --> 00:07:50,000
bit more of this vertical look at impact with that right arm really straight. It'll be even

00:07:50,000 --> 00:07:55,000
clearer when we look at a few amateurs that it's really that straightening in the arm that causes

00:07:55,000 --> 00:08:02,000
the majority of the rotation down here at the bottom and less of a active twisting of the shaft.

00:08:03,000 --> 00:08:09,000
Okay two quick examples from down the line what we'll see over here on the right

00:08:10,000 --> 00:08:15,000
can be a little tricky to tell the amount of rotation so one good little check point is you if you

00:08:15,000 --> 00:08:22,000
get the club to let's say halfway between shaft parallel and impact typically the golfers you

00:08:22,000 --> 00:08:29,000
do this will have more of an open club face and it'll be pointing more out perpendicular to the

00:08:29,000 --> 00:08:34,000
target line instead of at the golf ball golfers who've had that shaft rotation or getting the

00:08:34,000 --> 00:08:39,000
arms more in front at this point and by this position the club will typically be pointing at the

00:08:40,000 --> 00:08:46,000
now unfortunately that's not absolute here's a golfer that appears to have very little rotation

00:08:47,000 --> 00:08:54,000
but you can see that because of the severity of the closed club phase you can see that it's

00:08:54,000 --> 00:09:00,000
pointing at the golf ball at this time so you can confirm it by looking at the position through

00:09:01,000 --> 00:09:07,000
the relationship of the club face through that space. Remember we saw with Dustin Johnson that even if

00:09:07,000 --> 00:09:13,000
you have a stronger grip having a gradual and gentle closing in the club face through shaft rotation

00:09:13,000 --> 00:09:19,000
matches preferred body and arm movements for developing a really consistent impact position

00:09:19,000 --> 00:09:26,000
and a good flat spot. So here's a golfer who breaks the rule but is doing more so with the

00:09:27,000 --> 00:09:33,000
in-plane movement let's take a quick look at the face on so that you can see what's going on or

00:09:33,000 --> 00:09:39,000
why that's happening. So we wanted to confirm with the face on remember the golfer on the right

00:09:39,000 --> 00:09:44,000
there was having a little bit of face rotation through this phase but you can see that it's corresponding

00:09:44,000 --> 00:09:50,000
with more the grip releasing here on the right side of the body. Same thing over here we didn't see

00:09:50,000 --> 00:09:58,000
very we saw a very little face rotation but we did see it happening a little bit down at the bottom

00:09:58,000 --> 00:10:04,000
so you'll see that it's pointing more at the target through this straightening the arm along

00:10:04,000 --> 00:10:11,000
the right side of the body and that'll typically cause the club to come up very quickly.

00:10:12,000 --> 00:10:17,000
Same thing over here more along the right side of the body and so the club tends to come up quickly.

00:10:17,000 --> 00:10:22,000
You'll often see it accompanied with a chicken wing or bending in the arms. So hopefully that helps

00:10:22,000 --> 00:10:28,000
you understand what it's like to try and visualize this axial rotation or how much the

00:10:28,000 --> 00:10:33,000
you're squaring the club based on club rotation or in-plane shaft movement.
