Tired of CrossFit? Give Spartan Group X a try at this West Town fitness facility. The workout is inspired by the Spartan Race, where participants run through an obstacle course that features fire, barbed wire and other dangerous obstructions. The studio, which opened in the summer of 2013, also features boxing classes, bootcamp sessions and Piloxing, which infuses Pilates with boxing moves. Coming soon: CrossFight, a class that combines cross training, endurance training and mixed martial arts.
