The TriggerPoint CORE™ Roller is the ideal foam roller for anyone that is new to foam rolling or recovering from an injury. The high density EVA foam delivers moderate compression with minimal discomfort. Its GRID pattern technology makes it the only solid foam roller on the market to channel blood and oxygen while you roll. The multi-density surface pattern is designed to break up knots and increase mobility, so you can move and feel better. Available in two sizes, the 36-inch TriggerPoint CORE supports the entire spine during yoga, Pilates, and recovery exercises and provides stability to roll large muscle areas, while the 18-inch CORE’s versatile size can be easily repositioned during exercise to support a variety of massages and mobility routines.
