At 18" long, the Rollga ISO is big enough to treat the whole body and small enough to fit in a backpack. This omnidirectional functional training roller is designed to stabilize hips, align the back, and increase range of motion. Ideal for muscle recovery, fascial health, and functional restoration of movement. Ordinary foam rollers cause discomfort and pain due to the unfitting design. This groovy foam roller is designed and contoured to fit the body and reach trigger points that are difficult to reach with an ordinary roller.
