When I think of the mini-trampoline, my mind jumps back to the early 80s when my sisters and I would take turns using the trampoline and later we'd all work out with the Jane Fonda record. (Wow. I really dated myself there. But I was young in the early 80s. Really young.)

Now those mini-trampolines are called rebounders. While the equipment itself doesn't seem to have changed too much (though some have added features for folding and storage), the workout has improved with time. Take the Urban Rebounder system, for example. You don't simply bounce around aimlessly. The rebounder comes with a fitness DVD that will guide you through a 30-minute set of twists, squats and other moves.

The Urban Rebounder system isn't the only one available. Check out your local sporting goods store for more options, or do a quick search on the Internet for "rebounder." Want more fun fitness ideas? Check out AOL Health.
