Why we chose her: Her passion is matched only by her body's ability to channel it.
Take it from a pro: "Serena is blessed with a solid, hourglass, athletic build with muscle mass. It suits her game, which is all about power. Every one of her strokes requires a chain of balanced muscular events that begins at her feet and goes up through her legs and through her core and spine. She finishes with her really strong arms, making impact through the ball. That transfer of power is a sight to behold."
-Esther Lee, Williams' Physiotherapist
