The CanDo Black Composite, Extra Firm, Half-Round Foam Roller is the ideal roller for muscle restoration, massage therapy, sport recovery and physical therapy. This is the PERFECT tool to use following intensive workouts, like crossfit, yoga, Pilates, weight training, bodybuilding and even dance. As seen in PT offices and gyms nationwide, this Foam Roller is ideal for stretching and rehabilitating hips, legs (thighs, knees, calves, ankles) back, neck and shoulders. Use for a deep tissue massage after an intensive workout to gain much needed relief. Built to withstand a multi-user environment, these rollers are durable as they feature premium molded foam that is firmer and more rugged than polyethylene, allowing them to hold their shape after repeated use. The durable roller can be used by large adults and highly active children. It fits all body types and is uniquely designed to fit the needs of both beginners and professional athletes alike. This roller is sized 6" x 12". The composite foam roller is great for increasing blood flow and improving blood circulation. It's wildly effective alone, but also works great in tandem with other exercise equipment. Works wonders on loosening and unknotting tight muscles while restoring flexibility. These rollers are also a great tool for ankle stretching and knee rehabilitation. Because of their strength and durability, they can be used as a rocker board by standing on its flat side to improve balance. Easy to clean, the entire roller (including the bottom), is closed cell, unlike other half-round rollers. This is a commercial grade therapy roller built for multi-use environments but available for home, personal use.
