How does that stack up with golfing machine principles?Well, i'm no science buff but i do have some goold ole common sense:

HOWEVER
This is all kinda moot because the upper left arm IS ALREADY pinched against the upper left chest muscle...its a power source
) I just started fiddling with keeping the arm and chest together during the backswing and downswing and there seems to be some benefit - also inhibits my huge overswing. Where is this aspect covered in the TGM book? I didn't see it during my first few passes.Originally Posted by rwh Mr. Kelley identified four separate, sequenced periods of acceleration in Chapter Eight. In order, the chain is #1, Shoulder Acceleration (Start Down); #2, Hand Acceleration (Downstroke to Hands approximately at the Right Thigh); #3, Clubhead Acceleration (Release -- Hands go from Right Thigh to Impact); and, #4, Ball Acceleration (Impact).
On your own, You learned that the turning shoulders must start your Acceleration Train -- not your arms or hands. Properly subordinated, your arms and hands won't get out of sequence and you will have all the "connection" you need.

Chapter 8 often gets overlooked from the aspect of Acceleration and it's four stages

You can't compare hitting a baseball (a moving object at anywhere from 50-100mph) to hitting a golfball which is STATIONARY.
Also, a golf ball compresses A LOT more than a baseball does. So, regarding newton's law of equal/opposite reaction, the "opposite" reaction from hitting the baseball (left arm pinching against the torso) is going to be a lot more than a golf...
