This corporate-ish chain gym has nine locations across the lower half of Manhattan. While that might be a turn-off to alt-fitness aficionado, when it comes down to it, what that means is a surplus of equipment, convenience, and too many classes per day to make excuses about missing. Pools, basketball and racquetball courts, and rock walls are some of the facilities included with membership. There's also nutrition planning, massage, and personal training among other extra services. For the squeezing-it-in-after-work sect, it's gets the job done.
