In this video, you will notice how Roger Federer uses his legs during the service motion. Progressing from the bending phase through to the point where his legs are fully extended, Roger can produce the maximum vertical energy.

This technique allows him to hit the ball at a higher impact point and generate more energy at the moment of impact. It is important that the vertical push is in line with the ball at 12 o'clock in order to ensure the proper balance during the shot.
