I bought an exercise ball. It really did help strengthen my core. The "best" part was that, you know how people say you shouldn't be sitting down for too long? The exercise ball was so uncomfortable that I was forced to talk a walk every 45 minutes or so. I don't know if people with back issues should take my advice though. |
