There's wi-fi and air conditioning throughout, staff trainers, and guided workouts, with locker rooms and showers. It's open around the clock every day, with coaching and personal training available as optional add-ons. It's best suited to advanced lifters and athletes looking for a serious, well-equipped strength and conditioning gym.
