Weight Forward - Using SwingCatalyst and SAM Balance Lab to Explain Pressure Throughout the Swing

Nice video guys.  Really cool to see Grants numbers.

Some of the other videos/pictures that we have seen make a lot of sense now. 

Yes. Yes they do.

Grant's trace is as smooth and elegant as his swing. Amazing!

I was in a discussion over at Richie's forum discussing parts of this issue. The logic of the poster there was that your arms and clubshaft are heavy enough to cause the weight distribution to move to the right in the backswing and it is not act of the right leg straightening that causes the pressure to increase on the right. The only way to counter the weight of your arms and clubhead is to move your hips toward the target (ala Troy Matteson) to counterweight your arms. Theory being that even if Dave/Grant/Suzann had not straightened their leg the weight would still move to the right.

 

 

I wonder what you guys think of this comment?

 

This is great information.  Love seeing teachers wanting to continue to learn.  I thought those 3 golfers (Petterson, Waite, and that bald guy ) were perfect examples to show the slight differences within the commonalities.  Petterson all the way down near 80% forward at impact vs. Waite at 95% and Dave is in the high 80's.

 

One question though:  Dave makes a point to say that 80-95% is the range of good players while hitting an iron.  Was he just filling time there, or is there a discernable difference when hitting woods?

Re mchepp's comment -- I think it would be interesting to record two swings, one with a club in hand and one without and see if the pressure differentials change a little. 

First off, great job Dave and Erik!  Thank you for putting this together and spending all that time researching/testing.  Also thanks to Grant for spending time with us at Swing Catalyst, gotta say that was a fun day!  Not only does Grant's swing look awesome but his traces are super smooth.

 

 

 

Erik can probably elaborate or explain better than I can but these machines measure pressure, not weight.  Remember weight is a static measurement.  So club or no club pressure is increasing right because the rear leg decrease in flex.  

 

These two pics would disprove what that poster was talking about Mike because the arms and club are still to the right and the pressure is left.

 

 

 

 

btw maybe slightly off topic but love seeing Grant and Dave's swings from overhead.  

 

Good point, Mike.

 

I particularly like seeing where the pressure in the front foot is located when the downswing commences. The ball of the left foot really lights up red. 

 

A really important video that I think will help a lot of people.

Mike, if Grant and Dave don't mind, could you please post the raw HD video of Grant's 4-view on the Sand Trap YouTube channel. I NEED those for my models file! Cheers.

 

Also, am I correct in thinking that the pressure and weight distribution are the same at the three static points* in the swing -- i.e. address, top of the backswing and finish position? If so, how many people would guess by looking at him that this guy has 65 percent of his weight right?

* (Realize that there may not be a truly static P4 as and the arms and club may still be traveling to the top as the hips start forward. But I imagine the two must still be pretty close at this point?)

Appreciate the video.

 

I noticed this about Grant's transition, too, in watching "some other DVD.". He seems to almost settle into the end of his backswing when he immediately begins applying pressure with the ball of his front foot - an aggressive move, and one to which I must aspire to improve.

 

Thank you, 5SKeys. This is great analysis.

A huge thank you must go out to Dave and Erik for sharing this video on the SwingCatalyst pressure plate system, and mapping it to the video of Wedzik, Petterson, and Waite's model golf swings.

First, this is a very helpful video, and filled with quality swing nuggets of information. And it definitely identified where some of the confusion was found between the data presented by the 5SK video in comparison to the S&T 2.0 video. Thank you for helping me understand why there was conflicting data being reported by both camps.

Secondly, I believe this video truly demonstrated the power of using a combination of technologies to build better golfers; SwingCatalyst (pressure plate system), Flightscope (launch monitor), Analyzer Pro (instructional video editing software). It is amazing what we can learn from this type of analysis. And I'm excited to get this type of data on my own swing.

Lastly, I really want to express thanks to the Golf Evolution team. Having the integrity to share your findings with the golf community here at TheSandTrap is a trait that I think is the most honorable. This is public domain. And you are not hiding behind a vail on this SwingCatalyst data - or keeping your findings as your own 'instructional IP'. You've put your findings out there for the masses to see which is very much appreciated.

The Golf Evolution team that I've come to know over the last year is one I'd say isn't afraid to embrace technology. Isn't afraid to embrace change. And will find ways to incorporate their findings into their instruction, and communicate it to the golf world. Huge props for this. Please continue with your efforts. You are building better golfers every day.

 

As Dave said, that's largely bunk. I do think that weight can shift about 5% due to the arms and torso, but if you think about the geometry of the arms - the trail arm is all the way back at the start and actually moves forward during the swing. It isn't enough alone to offset the entire left arm moving backwards, but it offsets it some - it's not like BOTH arms are adding weight. More like the lead arm is adding weight towards the trail side and the trail arm is moving more towards the center.

 

And the weight of the club is almost nothing. It's not even worth considering.

 

 

Not to pick on Dave or Suzann, but notice how much of her motion forward occurs late (she does get to 95%+), and even Dave's finish is a bit later. Notice too how smooth Grant's trace is.

 

 

 

We'll probably make them available at some point. We have a few we could use.

 

3) From ~A4 to ~A4.25 to ~A4.5 the golfer will subtly push off with their right foot, their left knee will slide horizontally forward, their core will slide their hips forward, and you'll see another little spike in pressure on the trail side.

 

I've illustrated this in a graphic. 1, 2, and 3 are highlighted.

 

 

 

And notice how little movement is required (particularly between the third and fourth picture) in some of these cases (and note that even at the max Grant is 59 Trail):

 

Soaking it all in, soaking it all in. No questions ATM. Good stuff. Kudos for posting the "proof." That's unfortunately rare (probably since most people know their instruction wouldn't hold weight ... err pressure?).

 

This is really awesome stuff here. The illustrations with color are a really cool way to see what is happening. Thanks.
