Spynga = Spinning + Yoga. An unlikely pair, maybe? Surprisingly, the hybrid makes perfect sense. Peppy co-owner Casey drills me through intense military-style spinning ("Sit! Lift! Sit!") then brings me back to earth through serene yoga stretches ("Namaste."). The vibe here is pretty and feminine, but don't be fooled: you will sweat.
Best for: women, yogis, stress-release
Soundtrack: Leading ladies of pop: Gaga, Katy, Fergie.
