LOVE YOUR LUNGES

Even when she can't get to the gym, MTV VJ Susie Castillo (pictured with rapper T.I.) has a recipe for a quick but effective total-body workout. The former Miss USA does walking lunges while also doing shoulder presses or bicep curls with dumbbells. "Before you know it your heart is pumping and you're sweating. You're burning off calories and at the same time you're toning your entire body," she says. And be sure to keep your core stabilized and contract your abs for a tummy-toning boost!
