The surface of the Rumble Roller contains specially designed bumps that are firm, but flexible, much like the thumbs of a massage therapist. As you roll over the Roller, the bumps continuously knead the contours of your body, gently stretching soft tissue in multiple directions. This action erodes trigger points, helps restore flexibility, and brings quick relief to common types of muscular pain. By design, the Rumble Roller's bumps are firmer than muscle tissue, but much softer than bone.
It does the job and is really good for my stretching..
