The TriggerPoint CORE™ Roller is the ideal foam roller for anyone that is new to foam rolling, prefers softer compression, or may be recovering from an injury. The high density EVA foam delivers moderate compression, for a comfortable total body massage. 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 tight muscles, to aid in muscle recovery, improve flexibility, and enhance mobility.
