Following the life of Jackie Warner, an elite fitness trainer and co-owner of Sky Sport and Spa in Beverly Hills, WORK OUT showcases the body-conscious culture that has become synonymous with Los Angeles. With the help of several trainers, Warner caters to a clientele that includes celebrities, Playmates, jet setters, and anyone else who can afford the $400-an-hour fee. The show centers on a group of people who sport perfect hair and perfect physiques as they struggle to get along with each other. Drama arises as trainers learn to get along with each other while they also try to please both their clients and their boss. That leaves Warner contending with both the soap-opera-like conditions among her staff and her own growing tension with her jealous girlfriend, who can't understand why Warner spends so many hours trying to establish Sky Sport as one of the best fitness centers in the country.
