Taking compression from acquired motion to total motion
 

I often hear complaints that people who can compress the ball nicely during acquired motion cannot do so as well when moving up to total motion. What are some common causes, and solutions, for this problem? Overacceleration? Failure to bump the hip?

Stepping Stone
 

They do not comprehend the Finish Swivel and its geometry.

Hence, they do not -- and cannot -- accomplish it.

:)

Plenty of great ballstrikers who don't make a tgm geometrially correct finish swivel so i am wondering with your post are you saying that the "intent" to make a correct finish swivel is helpful to compress the ball?

Finish Swivel Fun
 

A powerful golf stroke requires that The Flail (Left Arm and Club per 2-K #1/2/3) work properly. In other words, the Clubhead must Overtake the Hands without destroying the Rhythm (RPM) of the Stroke. Classically, this is accomplished in three stages: Release Swivel; Hinge Action; and Finish Swivel. As the bridge between the Follow-Through (Both Arms Straight / end of Hinge Action) and Finish, the Finish Swivel is thus an integral part of the action. See frames 6 and 7 in Tiger's swing below. [Many thanks to KOC for the sequence. Click to enlarge.]



The requirements for a "tgm geometrically correct finish swivel" are satisfied when the In Line condition of the Left Arm Flying Wedge is maintained during the Snap Roll out of the Follow-Through into the Finish. That can be accomplished with or without the visual Flat Left Wrist. And golfers who grip the Club with a Turned Left Hand require less Left Forearm rotation than do those with a Vertical Left Hand.

Finally, there is at least one champion golfer -- Zach Johnson -- who does quite well omitting the Finish Swivel entirely. Hence the odd 'chicken wing' look of his Finish.

So, there are many ways to skin the cat . . . including not skinning it at all.

Relationship between Delivery Line Prep and finish swivel
 

Great explanation, Yoda. IMHO, one of the reasons people have trouble carrying compression over from acquired to total motion is that they do not focus on DELIVERY LINE ROLL PREP on full shots, but do from acquired motion position. When I actively think about uncocking the left wrist on full swings, it helps me to compress the ball.

So, just to kind of put your and Pistol's thoughts together, in order to finish swivel properly, you have to be able to uncock and roll prior to getting to that spot. As Pistol implied, even if one does not finish swivel properly, attempting to finish swivel might help them to uncock and roll, which could very easily result in compression.

If I am on plane and go to both arms straight I find it nearly impossible to not have a proper swivel.
