The first three seasons featured many of the trainers who work for fitness trainer Jackie Warner, and some other aspects of the gym and its clients as well as Warner's other fitness ventures, and private life. The third season of Work Out ended on June 10, 2008, and was canceled. A fourth season is currently held in production, with eight different trainers cast for the show. Warner, will not return for the fourth season, after the network was not pleased with her interaction with the other trainers.
