What: "Dance Motivation Fitness" isn't your typical dance-based cardio workout. It's also a far cry from the standard "no pain, no gain" mantra of tough fitness instructors who bark commands, taunt, and push the boundaries to motivate. DMF instructors are all about the warm fuzzy (think: inspirational coaching), complimenting women on moves they do well and offering kind words encouragement. Each song -- which ranges from hip hop to salsa to pop -- has a choreographed sequence designed to pump up your heart rate, and the instructor's feel-good vibe really instills the full body-and-mind experience in each class.

Where: DMF Studio in New York, NY

Why: Non-stop cardio with positive reinforcement! It's a win/win.

Who: Zumba lovers, cardio class beginners, social types, free spirit movers, and anyone who doesn't jive with the drill instructor routine in a fitness class
