Strengthening the inside and outside of your thighs, as well as the front and back, will make you quicker on the tennis court. And you’ll walk with more grace and ease. Rond de Jambe Pressing through your buttocks and right thigh, extend your right leg in front of you. Keep your upper body stationary; only your leg and hip should be moving.

Complete a full set (kicking forward and back without touching the floor), then switch sides. More from Prevention: The Cellulite Solution
