This giant exercise ball is a high-quality stability ball that is perfect for balancing moves, crunches, squats, sit-ups, a wide range of highly effective core exercises and even for using as a bouncy, moving desk chair. It is also a perfect substitute when you simply need an alternative to using a traditional weight bench. For quality, and to ensure your ball doesn't pop or explode during a workout, we highly recommend the well-built Theraband Pro Series Exercise Ball.
