Sofia Vergara isn't wearing a bikini, but her sultry shape wins her a spot on this list. Sophia admits that she doesn't like to work out, but she still finds a way to fit in exercise. In a Self magazine article she explains, "I'm not athletic. But I love dancing to Latin music, so I have a trainer who dances with me for an hour, three times a week. Nobody wants to see Gloria (her Modern Family TV character) with a flat ass!" To buff up your booty like Gloria, take Zumba, a Latin-dance-inspired cardio class, which focuses on shakin' your salt shaker and hips for maximum butt-lifting results.
