There is a fitness oasis smack in the middle of downtown. The YMCA is well equipped enough, with benches, squat racks and treadmills aplenty, yet somehow devoid of that bane of the typical gym experience: other people. Those who just want to work out and go home can do so without wait times, predatory personal trainers or testosto-grunting. If you do stick around, the swimming pool, racquetball, basketball and squash courts, saunas, whirlpools and steam rooms are also both adequate and largely available. But the best-kept secret is the rooftop track, which, if you can find it, offers a secluded run amid the skyscrapers. Alas, like any oasis, this is bound to dry up. The current location will be replaced near the end of next year by a new, state-of-the-art one that's bound to attract the mirror-hugging masses.
