As I cannot deepen the Mac O'Grady and TGM stuff more because there are no possibilities to discuss it without problems anywhere today in the net I guess, I thought perhaps it is a good idea to investigate some simple but true biomechanics in golf that may be of use in my teachings. I am sort of familiar with MacKenzie stuff although such kind of information is too complicated and detailed for me. I have seen recently the Athletic Motion Golf channel on You Tube which I like to watch but it is too cryptic and without references to past time champs swings. I woner what are the recommendations here. Thanks.
