The Ultimate Proving Ground
With stationary bikes, medicine balls, dumbbells, ropes, gymnastics rings, and multiple Olympic-caliber weightlifting platforms, The Ultimate Proving Ground can look more like a fitness playground than a gym. An open floor design topped with synthetic turf helps to optimize speed and power development during boot-camp classes as well as personal, buddy, and small-group training sessions. MMA classes take place in the Ultimate Proving Ground's MMA Octagon, where students learn a blend of self-defense, judo, MMA, wrestling, kickboxing, and various heavy bag striking techniques.
