Tomas Berdych Photo #8: Knee Bend and Body Arch on Serve

Berdych loads up for his serve with a strong knee bend and body arch that prepare his biggest muscles to make a major contribution to his serve. Reaching after the toss with his left arm helps Tomas keep the toss consistent and puts his right shoulder in the lowest possible position so that it has farther to rise, and thus farther to build up speed, as he strikes upward at the ball.
