How is this applicable to a golfer during the swing? Perfectly understood if thats not free information.
66er,
Great question... It is in my retail products and prefer for it to stay there for now, it is a major area of study that I embarked on late last summer. The Lead Arm steepens relative to the ground much more than people think on the downswing...
There are some other areas of study that are very important:
Lead Arm to Trunk Relationship
Lead Arm and Club Offset Angle
Levels of Ulnar & Radial Deviation
Initial downswing acceleration of the lead arm - MAYPOLE SWING STYLE - that will effect the lead arm replacement
There is a paper on this subject coming out I believe at WS Congress 12
