The GoFit 55cm Stability Ball is a fun, yet challenging way to stretch, tone and tighten your body. What makes the GoFit 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 total body workout is very efficient, allowing you to see the results you want in a much quicker period of time.
