RELIEVE MUSCLE PAIN & BOOST YOUR RECOVERY TIME: Relieve aches, pains and muscle tension with a Core Balance Grid Foam Massage Roller. Roll muscles over the roller to break up soft-tissue adhesions and target painful trigger points 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 textured surface acts like the hands and fingers of a masseuse to target, loosen and release tight muscle knots more effectively. INCREASE YOUR PERFORMANCE FOR MAXIMUM RESULTS: Rolling your muscles helps release toxins and increases blood and oxygen flow to the target area. Use before a workout to enhance performance or after a workout to speed up recovery and help prevent injury. EVA FOAM CONSTRUCTION FOR COMFORT AS YOU ROLL: The roller is made with EVA foam that is firm enough to deliver a deep muscle massage while remaining comfortable during use. EVA foam also maintains its shape even after heavy use. LIGHTWEIGHT & PORTABLE TO USE WHEREVER YOU GO: The massage roller measures 33cm x 14cm x 14cm. Its lightweight and compact design makes it easy to store and carry to the gym, yoga classes, Pilates sessions and more. It can be wiped clean for long-lasting and hygienic use.
