Orange Theory Fitness

Orange Theory's ultra-scientific approach guarantees many calories burned and a great workout sesh, combining running, rowing, and weight training all in 60 minutes. During class, the instructor hooks you up with a heart monitor, tracking your beats per minute and how many calories burned. Goal of the workout? Achieve as many splat points as possible (indicating you've gotten your heart rate up past a certain number). Everyone's burn is displayed on a screen, so it's great for competitive types.
