Within Guerrilla Crossfit's 5,000-square-foot enclave, a crew of certified coaches leads exercisers through the functional workouts at the heart of the discipline's pure fitness approach. As proctors of the gym's daily CrossFit regimen, the team oversees challenging workouts that spur participants toward short-term perspiration and long-term improvements in fitness, health, and overall wellness. The Workout of the Day, which changes daily, incorporates a string of exercises culled from a list of myriad movements, such as pull-ups, push-ups, rows, and planks.
