Some users prefer a single lacrosse ball pressed against a wall, or the floor. Others prefer the octagonal ball with the opposite hand pressing the ball into the chest. Position your shoulders to the back to open up the chest. Roll the ball slowly around the entire pectoral muscle. You can also raise your hands above your head, or out sideways to change the shape of your pectoral muscles, and allow the ball into different areas and release points.
