It was discussed a couple years ago after the golf articles but now some guys start to market it.
I'm not sure if that is good. As far as I know dr. G. is not accepted in the biomechanics community and his PhD is not in anatomy or biomechanics but engineering.
So is is ethically questionable to teach the stuff, maybe even dangerous to the spine like some golfers argue?
The core is of course important in rotation but the common wisdom is that it is contralateral contraction of the obliques and not side bending that causes rotation.
I know there is some side bend in the swing and the spine is not just a stiff rod that turns but should people really use and market Dr. Gs spine engine stuff?
