The R3, an acronym for roll, relax, and release is a massage and muscle tension release device. The device is manually attached through a secure bolt mechanism, fastening it in place for the user as they perform myofascial roller exercises. Built to last in commercial settings this roller is essential to relax tense and overworked muscles, decrease lactic acid built up and enhance balance, flexibilty and strength. The R3 is compatible with the Pro series Power Plate machines only.
