Medicine Roller Description from Pro Source
Through simple techniques, you may control the amount of pressure "the bumps" apply to your body. "The bumps" are evenly spaced to one another, so several of them simultaneously contact your body during most exercises. However, with a slight shift of your body, you can reduce your area of contact with the ProSource Roller, which increases pressure and provides deeper, more penetrating relief.
