Why: Increases mobility in the hip adductor muscles.

Who: Skiers, tennis players, and other lateral-motion athletes.

How: Lie facedown with forearms on the floor. Bend your knee slightly and rotate your hip outward. Put the foam roller underneath your inner thigh just above the knee, keeping your leg extended. Roll your inner thigh back and forth.
