KUSA - The 15th season of The Biggest Loser is underway, and this season is all about second chances.
"They're [contestants] vulnerable," the shows trainer Bob Harper said. "They're opening themselves up, exposing themselves."
Viewers will see American Idol winner from season 2 Ruben Studdard appear on the show.
Harper says the team is lucky to have him.
"He's been hugely successful in his music career," Harper says. "He's been struggling with his weight for a long time. I think it took a lot of strength for Ruben to be on our show."
During the 15th season, some of the kids who appeared in an earlier season as they battled with obesity, will also return.
The Biggest Loser airs Tuesdays at 7 P.M. on 9NEWS.
