The Sports Center at Chelsea Piers
Where: Chelsea
Why: Few gyms get better than this: state-of-the-art sports facilities, 100+ classes, 10,000-sq-ft indoor rock climbing wall, an indoor sand volleyball court, 3 indoor basketball courts, a pool, track, and boxing ring, AND a beautiful water-side sundeck for when the weather warms up. Oh yeah, did we mention all that's all in severely space challenged Manhattan. New programs for members and non-members alike include a half-day triathlon camp on Saturday and Sundays through march, as well as "The Beast," an intense boot camp that takes no prisoners. Thankfully there's a sauna and steam room to help you recoup.
The Deal: Join in January and get February free!
