I'm somewhat in the same boat as you. I define shallow based on the clubhead distance to the ball at any given height. And the shallowing movement of transition, when the COM drops under the hand path vector is a key type of shallowing. So I'm confu…

Hi Joseph,

Every instructor will have different orders and priorities. Looking at your swing, I think the release is the place that could use the most tidying up. It looks to me like the arms work around the body down in the release instead of wit…

It's earlier than you think, that's why I think it has to be more of a sequencing issue. The trigger of the downswing. Here's two graphs, one where you can see when the lead arm lowering starts (maybe P4.1). The second graph is just to put in perspe…

Yes, I always thought the two trends were less pull down from the top and less pull down through impact :)

Hi Mark,

Yes, I do think in general long drivers tend to have a little bit more of an arm pull pattern. It can help with speed, but often sacrifices consistency and low-point control.

That said, I think you can do it with the body by emphasizing …

Here's a few of the lead shoulder lift graph. The first three are pros and then the second two are amateurs with more of an arm pull pattern. You'll see some subtle differences.

Hi Guy,

I'm happy to try and get to the bottom of things. It helps me understand and explain better. Unfortunately, Mike and Shaun never responded to my questions, even in the big private group chat. So they appear to have chosen to sit this one o…

In my experience, the ball sliding up the face usually comes from too much axis tilt and the rib cage staying in flexion too long. This usually creates low point issues and shaft lean/trajectory issues.

The tricky thing with your question is handl…

I had a question come in from a member that I wanted to share. He said:

"I’m trying very hard to understand the relationship between hip turn and posting on the left leg. Does posting end the hip turn? Sequencing the two? How does too much hip moti…

Hi Guy,

I've been involved in some chats with people from different systems, so here's a quick summary of this video:

The creator of the GEARS system states that his software does not at the moment report internal or external rotation. So the dat…

Here's some actual data showing the external rotation from a couple of other systems. I'll discuss this and other issues in the video deeper in my next coaches certification call at the end of the month.

But here's the responses I posted on Facebo…

I'm digging into it deeper. I found some data from Dr. Rob Neal's system as well as another golf coach who has external rotation built into his AMM parameters. Both of them show the trail arm going into external rotation during transition. So I'm tr…

I'd be curious to see more of Mark Bull's data as well. I'm pretty sure he uses a Polhemus system (AMM), which has advantages and drawbacks. Depending on how the system defined top of the swing, I actually wouldn't be that surprised if the shoulder…

Hey Guy,

Thanks for sharing. Unfortunately, they didn't really address any of the key questions with that video. We still don't know how they are calculating the different shoulder movements. Their definition of shallow vs steep isn't a metric eith…

Hey Trevor,

I hope the yoga block is helping you build some clubhead awareness. One thing to watch out for is in the video you posted, you rotated your body a lot less (see image). So you want to make sure you're still using your body, but avoidin…
