Kerri Walsh, along with her partner Misty May-Treanor, has dominated the sport of beach volleyball for several years now. They won gold in Athens in 2004, and they're back for this year's games in Beijing, ready to repeat.

Kerri has some specific exercises that she feels are must-dos for her sport. She's a big believer in Pilates, as core strength is incredibly important in volleyball, and does "fast twitch training with her trainer Tommy Knox," which helps her to have greater boosts of strength and speed. Additionally, Kerri makes sure she does squats, shoulder exercises, cleans, and lunges. For cardio, she incorporates intervals to improve her performance.

Like anyone who trains as hard as she does, Kerri does experience the occasional injury. She recovers by drinking lots of water and using ice and heat. She also uses massage to get her body ready to compete.
