Totally agree to the above, where most people are using the right (rear Heel) to push forward, where the right heel should be totally passive. The head turn and the rear heel lift is a result of the force pulling the body, just like we were on the SWING,when we are younger, while we let the force take us forward.
We transfer power to the swing, then when we reach the highest point, then we knee down and accelerate with the swing, and the minute the swing reach the bottom of the arc. the Swing still travel and then it swing up.....
Do we have to rotate, or the force take us round?
