Biggest Loser trainers Bob Harper and Jillian Michaels understand the importance of combating the epidemic of childhood obesity, which is why they hope to make a dent in this nationwide problem by helping the children on the show with their self-esteem and making healthy choices.

During our interview, Bob Harper pointed out that the rules of engagement are, of course, a little different. “When you see Jillian and I working in the gym with the adults, we’re banging it out,” he said. “We’re doing the exact opposite with the children. We’re having fun; we’re getting kids to be kids again.”

“It’s about making health fun for them, active, getting them on a softball team, getting their parents involved,” said Jillian. “That is such a huge part of the problem— the parents and their lack of knowledge.”
