The Rumble Roller 12″ Manipulates Soft Tissue – Like a Massage Therapist! The surface of the Rumble Roller 12″ contains specially designed bumps that are firm, but flexible, much like the thumbs of a massage therapist.
As you roll over the top of the Rumble Roller 12″, 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 Rumble Roller’s bumps are firmer than muscle tissue, but much softer than bone, so they deflect out of the way if they contact your spine or other bony protrusions.
Through simple techniques, you can control the amount of pressure the bumps apply to your body. The bumps are closely spaced to one another (< 2″ apart), so several of them simultaneously contact your body during most exercises. However, with a slight shift of your body, you can reduce your area of contact with the Rumble Roller, which increases pressure and provides deeper, more penetrating relief.
RumbleRoller’s Premium Materials Provide Lasting Value
Before creating the RumbleRoller, we spent years studying other foam rollers, and testing many different types of advanced polymers. Our material research resulted in a product that has several times the strength and tear resistance of conventional rollers, has a wonderful feel, permanently retains its shape, and is guaranteed to outlast and outperform any foam roller that you’ve ever used.
The Rumble Roller’s smooth, nonporous surface repels most dirt. It is water-proof and includes a molded-in antimicrobial additive that helps prevent the growth of bacteria and fungus. To clean your Rumble Roller, simply wipe it down as needed with soap and water or any common household cleaner.
