Jillian Michaels (born 18 February 1974) is a fitness expert who gained prominence as a trainer on the NBC weight-loss reality series The Biggest Loser (USA). Michaels was the trainer for the red team until 2006, when she was replaced by Kim Lyons. She returned in 2007 as the black team coach, competing against Kim's red team and Bob Harper's blue team. Kim decided not to return for the spring 2008 season, leaving Jillian as the only female trainer. Along with Bob Harper, Jillian is also a trainer in the Australian version of the show. She began her career in exercise because she was considerably overweight before her teenage years (although not to the same extent as the contestants she whips into shape now). As a young adult, her mother enrolled her in a martial arts class, which was a new beginning for Jillian. Thereafter she dedicated herself to helping the overweight transform their lives and their bodies for the better. See Less
