RubberBanditz Burst-Proof Exercise Balls with Pump

I have had a few balls that burst after limited use. This ball is much more sturdy and does not need to be filled as often as the other balls I have used. I work out 5 days a week, and use this ball on all workouts, so I am looking for a ball that lasts.

Just kidding about the sit-downs, but I do get in some good eccentric exercises and back strengthening along with core abs.
