If Jazzercise is a fleeting '80s memory for you, like your
Betamax tape of ALF reruns or the "Frankie Say Relax" T-shirt you wear when bleaching the ceiling, today's Groupon gives you a chance to discover how the exercise phenomenon evolved into one of today's best total body workouts. 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. Expect to burn up to 500 calories during each round. Dancing with the Stars multiple-champion Cheryl Burke is a fan of Jazzercise's improvisational workouts, though you won't need her moves to get the most out of your class.
