On plane like Tiger
Tiger Woods is a living example of the power of the O-Factor. Notice his level hips, driving left knee and braced right leg, and how he manipulates these body parts to perfectly slot the club. Between photo 1 and photo 2, Tiger's hands drop just a few inches, but look how much his hips rotate. They move from about 45 degrees closed to nearly square in the blink of an eye so much for the theory that the arms start the downswing. Also notice Tiger's rear end he squats to start his downswing. That keeps his posture in check as his hips unwind at a rapid pace. In photo 3, check out how his right shoulder has dropped straight down as his left hip has turned up. As a result, his hands and club return to the ball on plane.
