Harper moved to Los Angeles in the early 1990s and began a career in personal training, developing a following of celebrity clients including Jennifer Jason Leigh, Ben Stiller and Ellen DeGeneres.

In 2004, Harper was cast as a trainer on "The Biggest Loser" alongside Jillian Michaels. It quickly became one of the most popular reality shows on TV. He spent 17 seasons on the show coaching severely obese adults through drastic weight loss. He was known for his gentler approach, in contrast with Michaels' tougher demeanor.

Harper's role as trainer on the show pushed him into the limelight and opened doors for him as a TV personality. His association with the show has led to TV appearances on shows like "Ellen," "The Tyra Show," "Larry King Live" and the "Today" show. He has also developed fitness DVDs, written several books and developed a line of nutritional supplements.

Personal Life

Bob Harper had kept his personal life quiet until 2013, when he revealed in season 15 of "The Biggest Loser" that he was homosexual. His disclosure was prompted by a cast member who was struggling with his own sexuality and coming out to his parents.

In February 2017, at age 51, Harper had a heart attack while he was working out in a New York City gym. He was rushed to the hospital where he was in a coma for two days. He survived and was released from the hospital after an eight-day stay. The cause of his heart attacked was determined to be genetic.
