Dr. Brian Gordon
In the final segment of Brian's original series on teaching the serve, he explains his fundamental rule for synchronizing the backswing and the leg drive: the concept of probation. Brian sees a universal problem in junior tennis. The tendency of the racket to enter the backswing far too early which destroys the impact of the leg drive and its ability to drive the racket down the back. See how he teaches the probation position and his surprising take on what creates racket speed - and what diminishes it.
