Work Out

Work Out in the Zone (previously known as Work Out) is an American reality television series on Bravo, which premiered on July 19, 2006. The show is centered on fitness trainers and models located in the many cities of California. 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 subsequently 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. The fourth season, which revamped the show's concept, mainly featured top fitness model and former army ranger Greg Plitt, who was the only cast member to return from the previous season.

Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, including strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, and merely enjoyment. Frequent and regular physical exercise boosts the immune system and helps prevent the "diseases of affluence" such as heart disease, cardiovascular disease, Type 2 diabetes, and obesity. It may also help prevent stress and depression, help to promote or maintain positive self-esteem, improve mental health generally, and can augment an individual's sex appeal or body image, which has been found to be linked with higher levels of self-esteem. Childhood obesity is a growing global concern, and physical exercise may help decrease some of the effects of childhood and adult obesity. Some care providers call exercise the "miracle" or "wonder" drug—alluding to the wide variety of benefits that it can provide for many individuals.
