How can the ground and your legs help you hit a winning backhand?
Use them together to start a powerful chain reaction.
Did you know the ground is where a great tennis stroke begins? It’s the first link in a chain reaction, something we call a kinetic chain of energy transfer. When a tennis player’s legs push into the ground, we know from Newton’s Third Law of Motion that the ground will push back with an equal force. The energy from that force goes into the tennis player’s body. The ground reaction forces are transferred up the kinetic chain into the player’s legs, hips, torso, arm, hand, racket and swing. A successful transfer of energy leaves a player with a lot of racket speed and a great backhand.
