I only know of Two actions by the golfer that can mess up (prevent) the "Magic of the Right Forearm". There may be many more.

1) Force the Radius of the Right Shoulder to Right Wrist, and the Radius of the Left Shoulder to Left Wrist to remain constant.
a. Grip a Club directly in front of you and lift straight up by powering the motion with your right shoulder and a Level Right Wrist. So, by preventing the Left Arm from crossing your chest, the Radius from the Left Shoulder to Left Wrist will be similar to the Right Shoulder to the Right Wrist.

2) Cock the Left Wrist with the muscles of the Left Forearm.

The Right Forearm Takeaway is an important procedure for creating these alignments and actuating the Left Wrist Cock by bending the Right Elbow and Raising the Right Arm.

The Loading Action of the Power Package would seem to be related to the Magic of the Right Forearm. However, 12-2-0 includes a "Snap" Loading Action. Hmm?

When I practice and experiment with the "Magic of the Right Forearm", my Accumulators, 4, 2&3 load with a "Full Sweep".

10-22-A FULL SWEEP This pattern starts the Loading Action at the beginning of the Backstroke and smoothly and evenly accelerates the Club ahead of the Hands so as to arrive in position at the intended Assembly Point.
