Unless regularly worked out, the human body's hunger for exercise will drive it to do push-ups whenever you lie down and bicycle kicks whenever you try to drive. Keep unruly muscles in line with today's Groupon: for $24, you get a 10-class punch card at Studio Boom (a $50 value).

Studio Boom's fitness instructors set hips swaying and bellies bopping to salsa, merengue, and reggaeton rhythms in upbeat Zumba classes. High-energy Zumba Fitness sessions can burn up to 1,500 calories per session, while less intense Zumba Gold classes suit all ages, ability levels, and surpluses of left feet.

Studio Boom supplements its Zumba classes with workout outlets such as African DanceFit, Belly Dancing, Boot Camp, and a multivitamin rich in iron. Within the studio, bright-green walls and international flags create a vibrant atmosphere reminiscent of a dance party inside the United Nations's motion-capture room.
