Trend: Hotel Super-Gyms
Who Does It Best: Park Hyatt at the Bellevue
Philadelphia

Those tiny hotel workout rooms with old, rusty equipment may be a thing of the past as more properties start teaming up with stand-alone gyms to offer fitness-minded guests a fuller range of exercise options. At the Park Hyatt you can work off that cheesesteak at the adjoining Sporting Club at the Bellevue, a 93,000-square-foot fitness center that includes an indoor track, pool, and basketball and racquetball courts, as well as a healthy café. Choose from more than 100 classes a week, including the Boxer's Workout, Urban Rebounding, and even a Foot Saver class that focuses on stretching your feet.
