The BOSU® Ballast® Ball 45cm is identical to the 65cm and is ideal for smaller spaces. It was designed to stay put and not wander during workouts. This ball has a six-sided surface design for proper alignment and positioning and has 2.5 lbs. of multi-dimensional load, which can provide a fun, visual effect and audible feedback during lifting, shifting, and shaking exercises. With the BOSU® Ballast® Ball, individuals can perform exercise progressions and dynamic drills that are not possible on a regular stability ball.

Beats any other exercise ball
Love using this in the gym! Totally kills for core workouts and more! Seriously a must have for any gym or home gym! The quality is outstanding and I don't feel like I'm about to burst the ball like the other cheap exercise balls.
