HiFi Fitness, Chicago

With more than 40,000 square feet of space dedicated solely to personal training, the trainers of Metro Personal Training have plenty of room to dole out exercise physiology, nutrition development, and training programs. Their philosophy is simple; put trained staff into a state-of-the-art facility and the results speak for themselves. Trainers run their own schedules and set their own rates, allowing clients to skip membership fees and annual contracts with the studio. Available fitness equipment comes from brands like Power Plate, Techno Gym, Free Motion, and TRX, which sit right by old standbys like tractor tires, sleds, kettlebells, sledgehammers, and battle ropes. Discounted parking and valet services are offered in nearby parking lots.
