Jillian Michaels (born February 18, 1974) is a personal trainer from Los Angeles, California. She is best known for her appearance as a trainer on The Biggest Loser.
Michaels was overweight in her early teenage years, until her mother enrolled her in a martial arts class. Inspired by her own personal transformation, Michaels dedicated herself to helping the overweight change their lives and bodies for the better.
