Lacrosse Ball

A lacrosse ball is a firm ball that can be used to perform self soft tissue release on tight muscles

Place a firm ball against the wall or floor; a lacrosse ball works best. Lift your arm up and across your body to expose the rotator cuff muscles. Press your weight into the ball and move your body in a circular pattern. You should feel a point of maximal discomfort, this is most likely the stiffest region of the rotator cuff muscles and will need the most attention.
