To whittle your waist, channel the 19-year-old singer and try having your own dance party at home three to five times a week. Turn up your favorite upbeat CD and dance around your house for 30 minutes, or purchase one of these dance DVD workouts, tested by FitSugar staffers, for a guided cardio workout.

Julianne Hough's Cardio Ballroom ($10, amazon.com). Right from the start, Hough's upbeat personality gets you excited about the warmups and choreography, and before you know it, you're doing the cha-cha, the jive, and paso doble. This is also the perfect workout video to do with some girlfriends.

Bar Method Dancer's Body Advanced Workout DVD ($20, barmethod.com). Led by cheery and pretty-to-look-at-while-you-are-sweating Bar Method teacher and actress Marnie Alton, the DVD offers a variety of the method's staple moves. Like the class, it starts off slow with leg lifts and light arm exercises (it's recommended you use two- to four-pound weights) and then jumps into the method's secret sauce: intense leg work at the barre.

Tracy Anderson's Cardio Dance Workout DVD ($30, tracyandersonmethoddvd.com). Anderson believes that dance cardio is the perfect aerobic workout for creating long, lean muscles and a feminine, toned physique. This workout is high-energy dancing full of hopping, jumping, high kicks, and even the '60s dance step the Pony. The eight combinations that make up the workout are like a jazzy version of petite allegro (the jumping section of a dance class).
