Foam rolling plus vibration in a manageable, compact ball, the Hyperice Hypersphere promises to keep your soft tissues loose for optimum flexibility while ensuring ease of range of motion. The ball’s rolling movement, backed by some serious vibrating, has also been backed by some of the world’s top athletes who use it to both warm up and recover from training and competition. While we may not be counted as all-conquering athletes in the GearCulture office, we give it an A+ too.
