While serving a prison sentence, of which an extensive amount was in solitary confinement, Coss Marte developed an effective exercise program without the need for any equipment. Using military bootcamp techniques, and additional secrets that Coss developed himself, he created the Conbody workout. Upon his release, he wanted to help other inmates bridge the gap between incarceration and the struggle to success. Coss wanted to help others find motivation and the path to living life on healthy, positive terms again. With that, he opened Conbody gyms, also bringing the workout in a streaming platform via Conbody live online.
