Release tight muscles with the Lifespan Fitness 90cm Foam Roller. Our muscles are in their natural state when they are elastic and flexible. After a tough workout or minor injury, our muscles might become tight and uncomfortable. Rolling a tight muscle over a foam roller has the benefit of massaging, stretching, and releasing deep tissue muscles. Our foam roller is made from a high density EVA foam to give you a firm resistance to apply pressure to a muscle. A dual density design layers a lighter density surface around a high density core so you can still feel comfortable while applying deep pressure. This product is durable, withstanding wear and tear from extensive use, making it suitable for use both at home and in the gym.
