The mind isn’t the only body part that grows bored with repetition. Muscles also need constant variation to grow and function properly, and few workouts provide this variation more than CrossFit, an intense exercise program that engages muscles with a series of functional movements. In fact, “engagement” is a good word to describe the entire philosophy behind CrossFit. The program’s instructors do everything in their power to keep participants engaged, motivated, and working so hard that boredom is no longer an option.

All of this is evident at CrossFit MNC gym, where participants push and pull weighted sleds, hold themselves high on gymnastics rings, and flip over tractor tires on a daily basis. Instructors stand by to offer instruction and shouts of encouragement as participants raise their chins aloft during pull-ups or head outside to fling cars across the parking lot. The gym’s ever-changing workouts blend gymnastics, running, rowing, and weightlifting—all of which are customized to suit individual levels of fitness.
