One of these days, you'll start getting up at five in the morning to jog around the neighborhood; you just haven't gotten around to it yet. When it comes to maintaining a slim physique, it's just easier to alternate that pack-a-day habit with moderately successful attempts at the "Master Cleanse" lemonade diet. Joining the Wells Street Athletic Club will cost you a pretty penny, but the steep membership fees offer built-in motivation for you to get off the couch and stop watching "Law and Order" reruns.

The folks at the WSAC offer a comprehensive health evaluation and free personal training to members, so that exercise newbies can figure out just what the hell they're supposed to be doing. You'll find all of the state-of-the-art cardio machines you'll need to work up a sweat, as well as free laundry service and showers to make sure you don't stink up the L on your way home.

Classes: As far as the classes go, WSAC doesn't quite subscribe to the whole "stripper pole" sect of group workouts, but you can get schooled in yoga, pilates and spinning here.

Extras: Add to this mix a steam room, climbing wall and first-rate juice bar, and your membership fees seem almost worth it, no? If you're still not convinced you need to join, get a load of this: The Station, a high-end salon, sits right on the premises, and members receive 20-percent off of the extensive menu of massages and beauty services, so you can even squeeze in a quick bikini wax while you're waiting for your spin class to start.
