HIPS & CORE

Serena will have worked hard on redeveloping the muscles in her hips, core and legs, which is where the power you generate for shots derives from, not your arms. That is what allows you to transfer the energy into the ball and hit it hard, and that is why Serena is so good. She has incredibly powerful legs and hips, and her arms, compared to some of the other women, are fairly imposing.
