Best of Both Worlds
Two is definitely better than one. The 3.5″ textured ball and the 2.5″ smooth ball give you two tools to break through tough tissues.
Included with every RockBalls is our Movement Manifesto, which outlines the dangers of a sedentary lifestyle and features a multitude of corrective exercises and tissue release techniques.
Corrective exercise can and should be performed anywhere and everywhere. Keep your RockBalls at home, in the car, or even travelling.
