F3 is a national network of free, peer-led workouts for men starting in Charlotte.

F3 is a national network of free, peer-led workouts for men that originated in Charlotte over 15 years ago. The organization's mission is to plant, grow, and serve small workout groups for men to invigorate male community leadership. These workouts are designed to be challenging for all participants while ensuring no one is left behind, and they are open to men of any fitness level. The community extends beyond the physical training to include social gatherings, races, and endurance challenges where bonds of genuine friendship are formed and strengthened. While F3 is not a religious organization, its members challenge each other to live for something bigger than themselves, believing they are not the center of the universe. The group has grown from its Charlotte, NC roots and is spreading rapidly across the country. It has gained recognition through features in Men's Health USA Magazine for January/February 2019 and on the Today Show in 2017. F3 encourages members to join the conversation and track their progress as part of a movement focused on virtuous leadership and community service.
