This gym is so nice inside that you wonder if it is okay to sweat. Vast skylights and huge windows create a rare workout environment that makes it feel like you are outside, minus the bugs, of course. Workout junkies can choose from cybex machines, free weights, aerobic classes, lap pools, spinning and Pilates, or play racquetball, squash or tennis. For those who prefer a bit of pampering, there are complete spa and salon facilities that include massages and facials. Be sure to check out the Relaxation Lounge, which serves herbal tea in front of a crackling Swedish fireplace. Juice bar, pro shop and child care facilities are available.
