Like the original RumbleRoller, the RumbleRoller Firm is a foam massage roller with flexible bumps that work like the thumbs of a massage therapist to deliver deep muscle penetration. This “Firm” version features 200 flexible bumps to give you a density that’s 35% more firm than the original. The bumps knead the contours of your body, gently stretching soft tissue (muscle and fascia) in multiple directions to deliver relief of muscular pain.
