Revolutionaries were once encouraged to eat cake, but here they're told to trash the cake (and carbs altogether), grab a towel and start peddling.

Revolution Fitness has a plethora of spinning classes as well as private instruction in pilates. (We were told, without apparent irony, the instructors are "very flexible.")  Aside from the spinning, Revolution also offers Pilates, strength training and Indo-Row, which is like a spinning class only instead of sitting on stationary bikes everyone's strapped to a rowing machine. And for those who aren't wild about counting points with Weight Watchers, the studio also offers nutrition counseling.
