F3, or "Fitness, Fellowship, and Faith," is a national network of free workout groups for men. Founded in 2011 in Charlotte, North Carolina, F3 aims to promote physical fitness, build community, and encourage spiritual growth among participants. The workouts are typically held outdoors and are led by volunteers, fostering a sense of camaraderie and accountability. The organization emphasizes the importance of leadership and personal development. Each session includes a workout, a brief discussion on a relevant topic, and a time for fellowship afterward. F3 is open to men of all fitness levels and encourages participants to bring friends and family to join in the activities.
