Daryl,
Ground forces need to be trained and can't be applied physically, time the message gets from the brain to the feet the golf swing motion has been executed.
Essentially should be applied the first move in the downswing.
We played with the idea of try this physical and measured ourselves and tons of others doesn't work needs to be trained.
Daryl I may up set a few people here. Has a Golf coach ever studied biomecahnics or how human body works in the golfswing.
No.
So they don't know how to teach how the hips are suppose to move effectively.
Truth is they are going on their belief system of how they think the pivot works.
I appologise here I'm a straight shooter and speak the truth.
