The surface of the GoFit Extreme Roller has firm bumps with an egg crate design. They work like the thumbs of a massage therapist. The bumps continuously knead the contours of your body, gently stretching soft tissue (muscle and fascia) in multiple directions. This action erodes trigger points, helps restore flexibility, and brings quick relief to common types of muscular pain. By design, the bumps are firmer than muscle tissue, but much softer than bone, so they deflect out of the way if they contact your spine or bony protrusions.
