Cross frictional massage is normally done by a massage therapist who uses his thumbs or fingertips to apply short, firm strokes across the muscle fibers. RumbleRoller's Gator is the only foam roller that can grip your skin well enough to mimic this type of massage.
If you look closely at Gator's surface, you'll see hundreds of tooth-like bumps with slightly concave ends, flat sides, and prominent edges. The bumps are very resilient, but have high lateral stiffness and generous skin-holding spaces between them. This patent pending surface grips bare or lightly clothed skin, and resists slippage in all directions.
EASY TO USE
Position yourself as you would for any rolling exercise, with your body on top of the Gator or otherwise pressed firmly against it. But instead of rolling, make an effort to shift your body an inch or so toward one end of the roller. During this time, the Gator's bumps should remain engaged with your skin, and you'll feel a tugging force on the underlying muscle. Repeat and reposition the Gator as needed.
