This is the set of three rollers that stretch and strengthen back muscles. Unlike similar back rollers, these units are designed to specifically target the area along the spine and between the shoulder blades and knead out knots in the myofascial tissues surrounding muscles. Each wheel-like roller is made of ABS plastic and lined with 20 mm-thick EVA foam to provide a durable yet comfortable apparatus. Each wheel can support up to 500 lbs. and they can also be used to stretch and massage other parts of the body such as your arms, legs, or neck. The set includes three 5"-wide wheels: 10" diameter (firm), 6" diameter (deep tissue), and 4" diameter (gentle). Also comes with a carrying case.
