Best Seller. The Rumble Roller is unique among foam rollers due to its pattern of bumps. These specially designed protrusions are firm, but flexible, making them remarkably close to a massage therapist's thumbs. When used correctly, this foam muscle roller gently stretches the back's soft tissue in multiple directions, eroding trigger points and relieving discomfort. Each bump is firmer than muscle tissue but softer than bone, which allows them to comfortably deflect if they come into contact with bony protrusions.

- 2 sizes: a 6" diameter for traditional body rolling and a 5" diameter for added portability
