As The Biggest Loser trainers Jillian Michaels and Bob Harper each publicly weigh in on their complicated relationship, we're doing a check-in with all 18 winners from the competition series.

Jillian Michaels has broken her silence on “Fit for TV,” the new Netflix docuseries about “The Biggest Loser.” Michaels was a trainer on the weight loss competition series from 2005, when the show premiered on NBC, to 2014, but declined to participate in the documentary.

Dr. Robert Huizenga fired back at Jillian Michaels ’ claims after she accused those involved in the new Netflix documentary, Fit for TV: The Reality of the Biggest Loser, of lying about the use of caffeine pills on the show.
