I am working hard now on getting myself into shape, but I have a limited amount of space, due to living in a tiny apartment (1200 sq. feet doesn’t sound small, but when you have 4 people living in that space, it starts to shrink FAST). So, when Amazon offered a 3-pack DVD set for fit ball exercises, which I happen to own, ;), it works out great for me. Plus, with this being able to be done in less than an hour, I can still have time to do everything else that I have to do.
