This is the set of three interchangeable rollers that help stretch and strengthen muscles for recovery. Each ABS roller slides through the 151/2"-long handle and is lined with EVA foam to provide a durable yet comfortable apparatus. Lightweight and portable for use at home or the gym, the set includes a smooth firm roller for small areas, an ultra-soft plush roller for tender muscle tissue, and a deep tissue roller for pre- and post-workout treatments. Ideal for targeting muscles in the back and along the spine, the rollers can also be used on stiff joints, shoulders, neck, feet, and legs. Each roller has a 5" diameter.
