Featuring a long strap that wraps around the athlete, this unique training device utilizes the body for manual leverage to relieve trigger points or muscle knots. The non-slip rubber knob targets specific and hard-to-reach areas for a stronger release. Adjustable nylon strap accommodates a variety of areas on the body and eliminates uncomfortable walls and floors from trigger point therapy. It also accommodates users of different sizes. Balanced plastic base equalizes tension and lets athletes smoothly roll on the pressure. After you're done, throw it in the included storage bag for easy transport and protection from damage when not in use.
