Pure Workout, Murray

The trainers at Pure Workout have stripped away the glamour of giant, impersonal gyms. They usher guests into a no-excuses zone where simple weights and calisthenics reign supreme, leading their classes with a potent mix of fitness expertise and tough love. Their routines vary, but each boot-camp session sparks friendly competition between attendees as they flip tires, heft weights, and sprint up hills. With no regard for noncommittal members who sneak helium into their kettlebells, the staff prizes Pure Workout's exclusive atmosphere—a quality that earned the gym a feature on NBC 5 and the title of CityVoter's Best Boot Camp in 2012.
