The man who coined the term "Functional Swing Plane" explains what it is and how to use the concept to help your game!

I made this device to show that when the CLUB FLIPS the body doesn't open AND that when the BODY DOESN'T OPEN, the club flips. 

That was easy to see but then I was surprised. I kept spiinning the wheel and no matter how I swung it the device always had a flipped bottom. 

Bertie Cordle from DST golf in England and Dr. Sasho MacKenzie, golf bio-mechanist from Canada proved that the club needs hit the ball with a lag impact for it to be an effective say to strike the ball. No great ball striker ever has had a flip impact.

I found that using this system, the best way to SWING a golf club and be able to get a non manufactured (I.E. not faked, or held but done using natural forces) lag impact is to take the club back so that the lead forearm is only a bit past parallel to the ground and to have a wide backswing with flow (energetic change of direction with rhythmic smoothness that converts backswing energy into downswing energy).

I took it to the range that day and the results were impressive. 

I would like to get some numbers to confirm it but the short swings (left arm to parallel feeling) felt VERY solid and compressed. When I took the club back full the dispersion got wide and the ball went higher and felt more glancing.

Interestingly the balls seemed to go about the same distance. I think using the clicker on my forearm and hitting shots before it clicks shows something important about flow and getting the energy out onto the ball before it is expended (flipped). 

Next I'll do a fuller practice session with some numbers. 

Some one sent me some of Kevin Ryan's videos who is a brilliant engineer with a good mind for golf that did some mechanic modeling of the golf swing that goes way beyond what I did. What I did was a DOUBLE PENDULUM which KEVIN says is how poor players swing. He said GREAT PLAYERS use an entirely different mechanic (14 minute video).

Most golf instructors I talk to see forearm rotation as a bit of an annoyance and something that introduces inconsistency. certainly most instructors talk about REDUCING the RATE OF CLOSURE, through the impact area. Here Kevin is talking about the forearm rotation being the CRUCIAL PART of the swing and not something to be avoided but something to be embraced. in his estimation the hinging and unhinging (extension and flexion of the wrists) happens very little relative to HOW MUCH the forearms snap through the zone.

The only missing part is the GOAL. I don't see Kevin showing how the conical pendulum model helps you get a LAG impact. and in some of the examples where he overlays the apparatus swinging super imposed on an actual golfer, it seems like Kevin TILTED the apparatus to match the rate of flip to the swing.

I LIKE the idea that FOREARM rotation might not de the DEVIL that traditional instruction has made it out to be. Worth more invetigation for sure stay tuned.

These are a doc I made with captures from the @kwon3D instagram page. 

More of a write up soon, my entire post just got deleted so for now. Presented without comment.

I think I'll do this again at night so u can see ball flight and drawing all the shot tracers is annoying.
