Relieve tense muscles with the IBF Iron Body Fitness Acupoint Foam Roller. Through simple rolling techniques using your body weight, you can control the amount of pressure provided to your muscles by the pyramid-shaped points, which act like the thumbs of a massage therapist. Relax contracted sore muscle tissues so that they regain their elasticity and increase circulation through myofascial release. Great for pre or post-workout stretching, flexibility, and injury prevention.
