"I've still got to pinch myself that I'm on "The Biggest Loser." We've had to keep this a big secret, and not tell anybody for over two months, and it's been really difficult," states Brett Hoebel, new trainer.
"I get teary eyed. Seeing the barn, and working out with the contestants, and knowing that happened a couple of months ago, and reliving it. It's pretty crazy," according to Cara Castronuova, new trainer.
Cara is a two times Golden Gloves champion, who was once ranked #2 in the nation in boxing.
While Brett is a 15 year fitness veteran, and trainer to the stars.
As an overweight kid Brett says he can relate to his contestants.
"It's not cool to be friends with the fat kid. I lost a lot of friends that way. Hard dedication. Changed the way I thought about myself, and sports, and turned it around," states Brett Hoebel, new trainer.
The new trainers must not only help their teams, but prove themselves.
"It's a lot of pressure, and I feel like we just nailed it, because honestly our contestants are doing great," states Cara Castronuova, new trainer.
