Hula-Hooping

This sport is not just for kids! Get lost in the hypnotic hip swivels of this super-fun belly blaster. Once you get comfortable with the basic how-to, you can mix and match these fun moves for a 30-minute workout that can burn up to 250 calories!

You'll notice more than just the inches you lose when it comes to looking in the mirror. "It makes us feel better about our body image," says Brandon, "and that will lead us to be more interested in physical and sensual activity."
