New & Improved Design: The ProSource Sports Foam Roller is a must have pre-and-post-workout tool for any athlete to stimulate muscle recovery and reduce discomfort. ProSource updated our design to give you a superior foam roller which offers a strong, EVA foam-filled center. The solid interior prevents cracks or breaking under heavy weight, unlike many rollers on the market, for safe, long-term use and dependability. Use pre-workout to prepare your muscles to safely move in their full range of motion, and decrease risk of injury. Use post-workout and on recovery days to relieve tightness, and increase flexibility. A grid of medium-firm bumps and grooves offers a variety of density zones to massage and stretch tight muscles. Foam rollers can be used on various body parts to reduce discomfort. Benefits: ProSource’s Sports Foam Roller is ideal for self-massage, to help break up knots, promote muscle relaxation, improve flexibility Evenly spaced large and small bumps and groves provide various contact points which mimic a masseuse’s finger-tip and forearm/palm massage. The targeted pressure provides a sense of relief by reducing pain in tight muscles and increasing blood flow for greater mobility and performance. Two density zones are perfectly balanced in our sports roller for the most comfortable exercise routine. The customized design makes it ideal for intermediate and experienced users who are ready to advance to a deeper massage. The full-sized 13” x 6” is easy to use and offers full-body coverage, suitable for any user.
