Jazzercise is 60 minutes of cardio, strength training, and stretching that incorporates moves from hip-hop, yoga, Pilates, jazz dance, kickboxing, and resistance training with handheld weights. Dancing with the Stars multiple-champion Cheryl Burke is a big fan of Jazzercise's improvisational workouts, though luckily you won't need her dance moves to get the most out of your class. If you're prone to first-class jitters, though, you can review the basic moves online before you go. Expect to burn up to 500 calories with each go-round.
