Tired groans and shouts of encouragement echo throughout Pro Fitness’s expansive exercise facilities, which host individual workouts and a diverse schedule of one-hour group classes led by attentive instructors. Socially inclined gym-goers sweat their way through classes such as Zumba, cardio kickboxing, Pilates, and yoga as instructors scour their persons for energy left unspent. Calories shrink in horror at the sight of seemingly endless rows of exercise bikes, treadmills, and weight-training equipment designed to maximize the efficiency of solo workouts. Wall-mounted flat-screen TVs keep minds occupied while bodies wrap themselves in cocoons of sweat and emerge as muscle-bound butterflies.
