The Ballast® Ball is like no other 65 CM exercise ball in the gym. This ball has a six-sided surface design for proper alignment and positioning and 1.5 lbs. of multi-dimensional load, which keeps it from moving during your workout. The Ballast® Ball provides a fun, visual effect and audible feedback during lifting, shifting and shaking exercises. The Ballast® Ball allows individuals to perform exercise progressions and dynamic drills that are not possible on a regular exercise ball.
