Goal: Feel smooth acceleration without the dominant hand
How to do it
Hit short chips with the lead arm only, trail hand behind your back. It's nearly impossible to decelerate without losing control of the club: the motion turns pendular by itself. Then put both hands back on and replicate the feeling.
On video, the chipping backswing is longer than the follow-through and the clubhead visibly slows down before reaching the ball.
