Release tension from the ground up. The DuoBall is a peanut-shaped massage roller built to free up tight tissue and improve mobility — starting at the feet and working all the way up the body. Its twin-ball shape sits either side of the spine and around larger muscle groups, applying pressure exactly where you need it without digging into bone. Roll it underfoot to wake up the arch, or work the calves, glutes and back to ease stiffness and move more freely. Made from high-quality, durable materials, it comes with a free online workshop so you know exactly how to get the most from it. What you get: Peanut-shaped roller for feet, back and larger muscle groups Targeted pressure that works around the spine, not on it Improves tissue resilience, mobility and recovery High-quality, durable construction Free online workshop included An easy, effective way to bring whole-body release into your daily routine.
