What do you suppose Peter actually has studied about how the brain moves the hands, in neuroscience or anatomy? How about “nothing”.

“The problem isn’t that you’re hitting too hard with the right hand, the problem is that your left arm is going faster than your right arm. So what happens in an exaggerated way is that the left arm pulls away and the butt end of the club’s in front, so the right hand tries to hit to get caught up. It’s not a hit with the right hand problem, it’s a too fast left arm, too slow right arm problem.”

The “fix”? Lodge a sleeve of balls between the forearms. Then if the lead arm outraces the rear arm, the box falls.
*****
CRITIQUE Even IF golfers “chase the front hand with the rear hand”, this “fix” “works” so long as the rear hand OUTRACES the front hand. So it trains rear-handsiness.
That’s just not good anatomically. Using the rear hand invokes using the rear elbow in the backstroke, which loops the sweetspot outside the aim line and rotates the putter face. Then using the rear arm./ hand in the forward stroke has the inside upper arm conflict with the rib cage and gets knocked into a pull path when approaching impact.
*****
The lead arm anatomically is superior for powering the backstroke and the thru-stroke. So the golfer needs to operate the brain to operate the body, by INTENDING to move the lead arm in the backstroke, by contracting either the front pectoral muscle or the front abdominal inner oblique muscle, and then INTENDING to move the lead arm in the thru-stroke by contracting either the front deltoid muscle or the rear abdominal inner oblique muscle.
The lead grip strength needs to be noticeably firmer than the rear, as this difference signals to the brain ”move the tighter body part.” The rear grip strength is adequate to “unify” the hands into one shape that does not alter during the stroke.
In this way, the lead arm DRAWS the rear hand and arm along in the thru-stroke.
Peter Kostis has this backwards.
