Last week I studied an excellent post by Daniel Gray, PGA Professional from Illinois, on Center of Gravity and Ground Reaction (http://danielrgray.com/center-of-gravity-and-ground-force-reaction-how-they-help-create-power-and-speed/). As I an avid user of BodiTrak COP technology I was immediately drawn to the subject, but what really is impressive are his instructions on physical training to lead the body into powerful positions of the golf swing. I practiced his medicine ball technique before recording one of my best lateral traces. In addition, my hips extended toward the target in a very relaxed posture. The drill starts from a golf stance, ball in hands, backswing turn, and bounce the ball behind your trail hip; you really get a perfect feeling of the initial on plane downswing move. Here is my latest lateral trace!
