It might be an activity that's done more for fun than fitness, but make no mistake -- hula hooping can be quite a workout. In fact, as CafeMom recently posted, it can even be used to help you slim down.

You can tone your tummy with a Hoopilates class or pick up a hooping DVD that will show you the ins and outs of getting fit with the hula hoop. Make sure you're using a weighted one for an extra challenge, and check out these easy moves that can get you started. Keep in mind that you don't always have to use your hula hoop in the traditional manner -- it can be used to tone all your muscles, not just the abs.

So it's no wonder Hula Hooping is catching on all over the place -- even Michelle Obama is doing it!
