Query: Awesome ball ; Ok video

The balance ball was easy to blow up (with some help). It took me a while to get used to it without falling off, but that's expected I guess.The VHS tape was extremely slow, as in it took forever for the tape to teach you the exercises. It really put me to sleep. But once I learned the exercises, I had no use for the tape. It was good in learning some basic exercises with the ball, but it definitely was a pain to sit through.Anyway, the balance ball is great for any exercise routine and this one is no difference. I've had the ball for a few months now and it hasn't deflated that much, even with kids jumping all over it at family parties. It's held up great and I'll continue to use it whenever I exercise.
