50 Years of Golfing Wisdom. John Jacobs

      The correct start down begins in the lower half of the body – the legs and the hips. That is why telling people to ‘stay sat down’ in the backswing, and to ‘get the left heel down first’ in the downswing, is often good advice; doing so consolidates the anchor point of the feet, and starts the hips swinging back into and through the address position. This automatically begins to pull on the arms and hands and unwind them towards the ball.

      Just as the swinging wrist-cock of the backswing ended with the actual cocking of the wrists, so the swinging uncock of the downswing ends with the uncocking of the wrists, as you unleash the power of your hands into the stroke.
