RumbleRoller Full Size X-Firm (Black)
Conventional Foam Rollers Compress Soft Tissue
Physical therapists, trainers, and athletes use foam rollers to relieve muscular pain and tightness (often called "adhesions", "knots", or "trigger points"). But conventional foam rollers have smooth surfaces that further compress soft tissue. Rolling on top of them improves blood flow and tissue flexibility, but the effect is limited and relatively superficial, unless you spend a lot of time rolling. The RumbleRoller was created to perform this therapy more effectively.
The RumbleRoller Manipulates Soft Tissue - Like a Massage Therapist!
The surface of the RumbleRoller 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 RumbleRoller, 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 RumbleRoller'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 RumbleRoller, which increases pressure and provides deeper, more penetrating relief.

Add Another Dimension to Your Foam Roller Program
The RumbleRoller's massaging action can be further intensified by changing your movement from a back-and-forth rolling motion to a side-to-side rocking motion. That's because the RumbleRoller's bumps have an asymmetrical shape that allows them to flex more easily in one direction. During rolling movements (i.e. the most common roller exercises, with the roller moving beneath you), the bumps flex relatively easily, and provide a wiping-type massage pressure. However, if you rock from side-to-side toward the RumbleRoller's ends, the bumps are forced to flex in a direction in which they're designed to be somewhat stiffer. This creates a deeper "digging" pressure.
Which Roller is Best for You?
The RumbleRoller is made in two different sizes, and each size is available in two different densities. The information below will help you choose the best model for your particular needs.
Full-Size or Compact
If you plan to use your RumbleRoller in a single location -- e.g. at home -- you'll love the full-size model, because its extra length makes it more efficient for performing many exercises. It's long enough to roll the widest part of your back in one pass; you can roll both legs (quads, hamstrings, and/or calves) at the same time; and you can even transition from one IT band to the other without moving the roller. With the Compact RumbleRoller, you'll need to roll each leg separately, and will spend a little more time repositioning yourself between exercises.
The major advantage the Compact RumbleRoller has over the full-size model is its portability. At just 12" in length, it fits easily in your gym bag, backpack, or carry-on luggage. This makes it a favorite of many runners and triathletes who transport theirs from race to race. The Compact RumbleRoller's smaller diameter (5" vs. 6" for the full-size model) allows it to conform better to the curvature of some body parts, such as your neck. The Compact RumbleRoller also costs less than the full-size model, which may be important if your budget is limited. Compact RR is perfect for travel
Original Density or Extra-Firm
If you're new to foam rolling or have gotten positive results from any type of conventional foam roller, you'll want the original density (blue). Even though this is our "softest" roller, it's still more aggressive than any other foam roller on the market. The extra-firm version (black) is intended for experienced users with especially dense muscle tissue that doesn't respond to normal massage pressure.
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 RumbleRoller's smooth, nonporous surface repels most dirt. It's water-proof and includes a molded-in antimicrobial additive that helps prevent the growth of bacteria and fungus. To clean your RumbleRoller, simply wipe it down as needed with soap and water or any common household cleaner.
RumbleRoller Safety Information
Both versions of the RumbleRoller (original density and extra-firm) have been tested by an independent laboratory in accordance with the Consumer Product Safety Improvement Act (CPSIA) of 2008 for lead and phthalates. Both toxins were below detectible levels, which the CPSIA considers safe for use by children age 12 and under. All RumbleRoller products are also latex-free.
Each RumbleRoller is packaged with an illustrated Instruction Guide that shows ten basic techniques for self-massage.
