RELIEVE MUSCLE PAIN BOOST YOUR RECOVERY TIME: Relieve aches, pains, and muscle tension with a GUTE Foam Massage Roller. Roll muscles over the roller to break-up soft-tissue adhesions and target painful trigger points (muscle knots) that can develop after a workout DEEPER PENETRATING MYOFASCIAL RELEASE: The foam roller features a hollow plastic core with a foam grid exterior for deeper penetrating myofascial release. The bumps act like the hands and fingers of a masseuse to target, loosen, and release tight muscle knots far more effectively. INCREASE YOUR PERFORMANCE FOR MAXIMUM RESULTS: Rolling your muscles releases toxins and increases the flow of blood and oxygen to the target area. Roll before a workout to increase your performance or use it after a workout to boost your recovery time and protect yourself from injury. EVA FOAM CONSTRUCTION FOR COMFORT AS YOU ROLL: The roller has been designed using EVA foam which is firm enough to deliver a deep muscle massage without feeling too harsh when you roll. Another benefit of EVA is that it retains it shape after heavy use, rather than degrading over time. LIGHTWEIGHT PORTABLE TO USE WHEREVER YOU GO: The massage roller measures 33cm x 14cm x 14cm. Does not come with yoga roller storage bag
