David Barton Gym - Chelsea

How do all those hot, buffed guys dancing shirtless at Splash tone their bodies (apart from eating nothing but protein shakes from Energy Kitchen and faux-ice cream from Pinkberry and Tasti D-Lite)? They work out at Chelsea's preeminent gym, David Barton, which has long had a popular gay following. This spotless, well-equipped facility is at 215 W. 23rd St. (212-414-2022).
