Effortlessly tend to your sore muscles at home with the RumbleRoller Deep-Tissue Massage Roller. This accessory features specially designed bumps all over the surface, providing firm yet flexible pressure when you lie on it. Similar to the thumbs of a masseuse, the RumbleRoller continuously kneads the contours of your body as you roll over it. Additionally, it manipulates soft tissue and helps restore flexibility. By eroding trigger points, the deep-tissue massage roller offers quick relief for many common muscle pains. Firmer than muscle tissue but softer than bone, the bumps move out of the way if they contact any bony protrusions. To intensify the massaging action, simply change your movement from rolling back and forth to rocking side to side. Available in several different sizes, the RumbleRoller effectively alleviates muscle tightness and improves flexibility.
