- Notice that the legs have already driven upward: the knees have straightened, and the feet have lifted off the ground. The legs begin the kinetic chain that culminates in the racquet-head speed that delivers spin and power to the ball.
- Elbow up, racquet down. Generally, the longer the racquet's path, the more time it has to build up speed. Dropping the racquet as low as possible maximizes its energy potential as you prepare to whip it upward.
- Body arched, like a bent bow. As the body (bow) straightens, it contributes more energy to the kinetic chain.
