Jillian Michaels and Bob Harper have changed the lives of many overweight families over the last 10 seasons of "The Biggest Loser" and now they've recruited two new trainers to carry-on in their footsteps.

Cara Castronuova and Brett Hoebel are the newbies for NBC's hit reality show and they each have their own personal connection to the contestants.

Cara's father passed away when she was a child, a tragedy she says could have been prevented if he had maintained a healthy body weight.

"It definitely affected me -- my dad's obesity -- because I saw that he was limited in a lot of ways and that he was sick in a lot of ways," said Cara. "And it really made me sad -- being a kid seeing that. Still to this day it makes me sad seeing family members that I have that can't do certain things like go shopping... And it's just about quality of life, so being able to help the contestants really helps me because I feel like I'm giving back and I'm making up for people that I wasn't able to help when I was younger."

Brett revealed that as a teenager he was fifty pounds overweight, saying, "By freshman year I weighed-in [for] football season at 170 and then sophomore year I wrestled at 120." Brett went on to explain that when he first started to gain weight in junior high school, he went from being picked first for sports to not being picked at all.

With their personal understanding of the contestants' struggles, the new trainers have an emotional investment in the success of the cast.

"I'm brought to tears by the contestants' courage all the time because of my past," said Cara. "And because of the family members that I have that are obese and because of just losing so many people to obesity and seeing the contestants here fighting for their lives and just pushing themselves past these challenges that we put in front of them."

Don't miss an all new episode of "The Biggest Loser: Couples" next Tuesday on NBC. Click the video to find out how Brett was chosen for the new season.
