This information was posted in my registration. If you are not a golfer, this will be difficult for you to understand. Dynamic Impact has the downward strike of the club against the ball and the swing bottom being 4 inches in front of the ball, with a flat left wrist and forward shaft lean. These are produced as a result of Dynamics #3 and #4, Loading on the backswing and Lag on the downswing with the delivery mechanism being the use of the workhorse (hips primarily).
