Hula Hooping

Hula HoopingPlay some jams, swirl your hips and have a hula dance party, all while working out your abs. Have fun with hula hoops and whittle your middle at the same time. The best part is that you won't hurt your back, and you won't have to keep count of how many crunches you're doing. Just hit play and sway! [Photo via Danielle Rufrano]
