The 65cm BOSU® Ballast® Ball is like no other ball in the gym. This ball has a six-sided surface design for proper alignment and positioning. It also has 1.5 lbs. of multi-dimensional load (ballast) which keeps it from wandering during your workout, providing a visual effect and giving audible feedback during lifting, shifting, and shaking exercises. With this ball, you can perform exercise progressions and dynamic drills that are not possible on a regular exercise ball.
