Club One Fitness

With 24-hour access, aerobic and mixed-martial-arts group classes, and well-appointed facilities, Club One Fitness aims to be the ideal backdrop for any workout routine. The schedule of group exercise classes includes yoga, Pilates, and Zumba. Boxers spar with other members or against the gym's stash of weighted bags during boxing classes for adults and tykes, who learn the pugilistic art in an Olympic-sized ring that, according to the Washington Post, "bears no resemblance to the worn, dingy boxing gyms of Hollywood movies, even though some Gold and Silver Gloves fighters, and a few pros, have trained there."

The staff of personal trainers and athletes show new members the ropes with three complimentary orientation sessions sessions; during the first, staffers talk to new members about their workout history and goals, and show them how to use Life Fitness treadmills, LifeCycle exercise bikes, elliptical cross-trainers, and stair climbers. On the second visit, they explain how to use Hammer Strength and Life Fitness strength-training and toning equipment. On the third and final visit, staffers give members their own personalized workout program, calibrated to help them reach their goals. From there, members can forge their own fitness paths or buddy up with a personal trainer.

Staffed by trained personnel, the bright and roomy childcare center keeps young ones engaged with toys, a big-screen TV, and a PlayStation. After adults catch their own entertainment in the cardio theater that projects movies as guests decimate calories, they can relax in the sauna, hop into the tanning beds, or shower off sweat and punching-bag tears.
