Slot Swing

When he began applying video analysis to the swings of professional and amateur golfers, Jim McLean quickly realized something: when he traced the plane of the clubshaft during the swing, the pros' clubshafts, nearly vertical at the three-quarter point of the backswing, were much flatter on the downswing, creating an X at the three-quarter point. No X's showed up in the traces of the amateurs' swings. In The Slot Swing, Jim shows you how to swing like a pro by dropping into the "slot" and making the X factor work for you.
