Biggest Loser Video: Preview the Series' Most Heartbreaking Moment Yet

The Biggest Loser‘s 17th season doesn’t kick off until Jan. 4 (NBC, 9/8c), but it’s already shaping up to be the series’ most emotional outing yet.

TVLine has an exclusive clip from the premiere, in which contestant Toy shares the heartbreaking story of her young son’s death, admitting that she failed to do her “one job” as a parent.

Trainer-turned-host Bob Harper does his best to comfort Toy, but the task becomes more than he can handle when the other contestants start erupting into tears.

Grab your tissues, dim the lights and hit PLAY on the preview clip below. Then, drop a comment with your thoughts: Are you already rooting for Toy?
