Bally enshrines exercise classes, calorie-burning equipment, and a fitness-focused staff within its sanctuaries of health. A 30-day membership includes access to a spread of group exercise classes, including Pilates, Reaction Cycling, and Step Fitness (class offerings vary by location). For self-guided worker-outers, cardio equipment such as treadmills, elliptical machines, cross-trainers, and stair climbers torch calories while entertaining the brain with video entertainment and integrated music systems that occasionally whisper quotes from Charles Atlas. Bally also boasts an array of strength machines, free weights, and small-apparatus equipment, and grants gym-goers access to on-site locker rooms, showers, and, at some locations, a pool and steam room.
