Sports Club/LA–New York

One of the toniest fitness centers in the City, this posh gym offers more than 120 classes weekly, more than 150,000 square feet of equipment, a rock-climbing wall, a pool, two full-size basketball courts and volleyball gyms, a boxing studio, a rooftop terrace, private training, nutrition classes, a spa, top-notch childcare and a café for building that strength back up when it's all said and done. No wonder some of the City's wealthiest residents call this their home gym—it's like paradise. And the huge window overlooking the Queensboro Bridge? Perfect for anyone who wants to show commuters how toned their butts have become.
