I suspect that she is using her right-sided lateral pelvic rotator muscles to initiate her pelvic rotation between P4 => P5, and then she is using her lead-sided gluteus maximus muscle and lead thigh quadriceps muscle to straighten her lead leg, which allows her to pull her lead foot back away from the ball-target line. I think that's a terrible training device because it makes the lead knee snap-straighten in an unnatural manner. It also does not allow a golfer to ingrain the "feel" of pushing the lead forefoot towards the ball-target line after P5 that will allow the lead hip joint to move back away from the ball-target line in a more natural manner.

Here is Mark Blackburn with his ideas on how the pelvis is rotated. I cannot understand how he can assume that creating the correct GRF horizontal forces in the sagittal plane (ie. push and pull forces via the feet interaction with ground) can actually prevent early extension . GRFs are a reaction to the correct anatomical muscular contractions that the golfer is doing , therefore Mark Blackburn is omitting that detail. www.facebook.com/reel/346742677845531DG

However, I do favor the idea of also contracting the right-sided lateral pelvic rotator muscles during the hip-squaring phase between P4 => P5. Jeff.

It won't cause early extension but I also think it won't prevent it from happening? DG
