how is a left sided swing a right sided thing?, forget the right arm and wedge in a left arm swing, the right arm doesn't "help" or should not "help" in a true swing through impact, the only help it should give is a little extensor and the right forearm startup, the left arm is pulling the number 3 pp down its delivery line pulling the right arm through, with it's proper closing and structure thanks to extensor which gives the arms their "effortless checkrein action"

push or pull pick one not both and you will be much better off

Well,,,,,I won't disagree. However, Right Forearm Participation is vastly underrated. I'm saying that when "Extensor" Action is applied, the Left Arm Stroke is a Right Sided thing.

I knocked off about 30 - twenty yard chip shots yesterday. Extensor action allowed the stroke Right Sided control. I added "Layback" to some of them. I had Left Side Control of the Clubface, and Right Side Control of the Clubhead.

1-F RIGHT ARM OR LEFT The “mystery” of the Mechanics of Golf fades away when Right Arm participation is understood (6-B-1). Whether its participation is active or passive is difficult to detect visually because in either case the Left Arm is ALWAYS SWINGING and the Right Forearm is ALWAYS DRIVING. But it is always a Left Arm Stroke unless the Right Elbow replaces the Left Shoulder as the center of Clubhead Arc. (10-3-K)

7-3 STROKES – BASIC ....
With this “in-line” relationship of Loading and Right Forearm, it is absolutely MANDATORY that, Hitting or Swinging, it is the Right Forearm – not just the Right Hand and/or Clubshaft – that must be thrown, or driven, into Impact per 7-2-3.
