One of the elements to body movement is the structure of the body from a face on view. We want to take the spine and tilt if forward and we want to avoid any lean to the side of the spine. For every degree that the spine tilts off of its access you lose two degrees of rotation. We want to have a well centered set up. Additionally, we want the inside of the right foot to be set outside the right hip and we want the feet to be in a good athletic posture, where you are ready to move athletically when you swing at the ball. Now what I want to do is describe the pivoting action. When you practice this put a ball in front of you. Get in a good set up, the spine should be tilted straight over the ball and what I am going to do is let the center of my body, somewhere in my stomach and sternum area, that is where I am going to feel my rotation. As I rotate into my back leg what I notice is that there is a little movement to the head and all of the sudden the ball looks like it is somewhat forward. Then I drive into the front leg and unwind. So the body movement is slightly lateral and primarily rotational. Keep the visual reference of the golf ball in front of you when you do this so that when you move back you know where that ball should be visually at the top of your backswing. You do not want to be looking down on the top of the ball. Again, the pivoting movement should be a rotation into the back leg then into the front and then around it. Blend that into your practice. Do it in front of a mirror and get a better pivoting action in your swing and it will give you more power and energy when you play golf.
