In the transition from backswing to downswing, the key factor is a pressure change where your weight transfers to your front foot. It's a move that is hard to see unless you're looking for it, yet it is the most important move in the golf swing because it sets up your downswing for good contact at impact.

As you make a backswing there are natural pressure changes that take place as the upper part of your body rotates against a resisting lower body in a process called coiling. As you near the top of your swing, your weight should begin to migrate to your front foot.

You probably already know you must make a weight shift, but it happens a lot earlier than most people think. Good players start the transfer of weight forward before the clubhead finishes going back, and it is this differential -- clubhead going one way, weight the other -- that translates into increased clubhead speed.
