High-profile bumps are a distinguishing feature of Rumble Roller products. Those bumps aren't just the whim of a crazy designer, though. Their size, shape, spacing, and elasticity all contribute synergistically to their effect.
Rumble Roller products are carefully engineered to:
Only premium-quality materials are used to manufacture Rumble Roller products, and our company invests heavily in product development and quality control. This insures better product performance and durability, and that means better results for you.
Full-Size 31" or Compact 12"
If you plan to use your Rumble Roller 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 Rumble Roller, you'll need to roll each leg separately, and will spend a little more time repositioning yourself between exercises.
The major advantage the Compact Rumble Roller 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 Rumble Roller'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 Rumble Roller also costs less than the full-size model, which may be important if your budget is limited.
