very good! indeed,
Verified Purchase(What is this?)
This review is from: New Gym Exercise Fitness Ball 65cm (Anti-Burst) with Dual Action Hand Pump & Travel Sack (Misc.)
I bought to use it as a seat while typing as recommended to me. brilliant, it took the back pain away. beside you can of course do the gym ball exercises. what i like about it, is the fact that i refill it with air, and then forget when I did so. it does not lose air constantly like other balls I bought in the past.
