The GoFit Ultimate Core Stability Ball is a fun, yet challenging way to stretch, tone and tighten your body. What makes the GoFit Core Stability Ball so challenging? Unlike training on a stable, flat surface, the ball is a round, unstable surface, so you not only train the primary muscle groups, but also the smaller stabilizing muscles as well. The stabilizing muscles are small, yet very important muscle groups primarily used for balance, alignment and posture.

The ball total body workout is very efficient, allowing you to see the results you want in a much quicker period of time.

As a general rule, the exercise ball should be large enough so that when you sit on it, your knees bend at a 90 degree angle. The 55cm ball is recommended for most people height 5' to 5'5" tall, the 65cm ball is recommended for most people height 5'5" to 6' tall and the 75cm ball is recommended for most people over 6' in height.

Suggested weight limit of 600lb.

Comes with ball pump, 2 ball plugs and an easy to follow exercise sampler. Also includes a 25-minute Linda Leene stability ball workout DVD.
