I've looked at a few videos (Jim Waldron Arm Swing Illusion - link below) and this other one by Stevan Bann below concerning the arm movements in the backswing. Does this mean that when PA4 is created in the backswing and then subsequently released in the downswing, that there needn't be any excessive pressure between the upper left arm and chest area (whether one uses an active or reactive pivot)? www.youtube.com/watch?v=ASH06DwHaRw

It is obvious that the left arm is elevated and adducted in the backswing to a variable degree, which varies considerably in degree between different pro golfers (eg. Bubba Watson versus Rickie Fowler). One doesn't have to adduct the left arm so that the upper left arm is adducted tightly against the left upper chest wall. Golfers who have a shortened backswing action, and whose left arm only gets to the 10 o'clock position by P4 (like Jon Rahm) don't get their left arm adducted very close against their left anterior chest wall. However, golfers who get their left arm to the 11:30 - 12:00 o'clock position (like Dustin Johnson) often have more left arm adduction. Jim poses at the 4:47 - 4:58 minute time point of his video, where he gets to a P4 position where he wrongheadedly states that the body is "blocking" the arms. I disagree 100%! If the right upper arm doesn't get behind the right shirt seam, then one has not pulled the right arm too far back. However, if the right scapula is over-retracted so that the right upper arm gets too far behind the body, then one would be "blocked". But, if the scapula doesn't move out-of-synchrony with the upper body (which is rotating clockwise during the P1 => P4 time period) secondary to an exaggerated scapular retraction phenomenon, then one should not have a problem where the upper torso is "blocking" the right upper arm. Steve Bannon only elevates his hands to just below shoulder level while keeping his hands opposite the center of his chest. However, his hands are not opposite the center of his chest at the P4 position after he rotates his upper torso clockwise That proves that he subconsciously adducted his left arm to a small degree when he rotated his body clockwise. His hands are opposite his right shoulder at his P4 position, but some golfers get their hands well behind their right shoulder at their P4 position (like Rickie Fowler) and that means that they adducted their left arm to a greater degree. One can load PA#4 efficiently with a shortened left arm motion that only gets the left arm to the 10 o'clock position (like Jon Rahm) and where the left upper arm is not pressed tightly against the left upper chest wall, and I disagree with Homer Kelley's conceptual idea of sensing the degree of loading of PP#4 due to "feeling" pressure of the left upper arm against the left upper chest wall as being a measurement of PA#4 loading efficiency. I never talk about PP#4 because I do not think that it is a biomechanically sound concept. I suspect that only a small percentage of pro golfers adduct their left upper arm so much that they "feel" tight pressure at PP#4 at their P4 position. Jeff.
