Kangoo Hip-Hop Dance
It's easy to laugh at those crazy, Rollerblades-esque Kangoo Jumps—until you try maneuvering in the bouncing shoes yourself. The footgear requires some serious leg strength and endurance, but Kangoo guru Mario Godiva Green swears they'll give you an "exhilarating feeling." In this hip-hop class, Green will help you get your bearings in the boots, then take you through a warm-up and easy-to-learn choreography. In addition to decreasing impact on your joints, the four-pound kicks act like built-in weights, which hone your calves and thighs as you work through the dance steps. Mention TONY when signing up on Green's website and get $10 off your first class through Nov 15. Club H, 423 W 55th St between Ninth and Tenth Aves (mariothetrainer.com). Tue 8:30pm; each class $20 (includes shoe rental).

According to instructor Sarah Callan, the trampoline also "helps with aerial awareness," encouraging you to think about how to move your body even in mundane situations.
