"The Biggest Loser" returns to NBC 5 this Sunday with a special two hour premiere that features a mix of old and new.
Trainer Jillian Michaels returns to the Biggest Loser ranch.
The hard-nosed trainer took a break from the show to become a parent.
That's given her an even greater appreciation for this season's twist: Incorporating three overweight teens.
The teens won't be traditional competitors.
There will be no weigh-ins for them and no eliminations.
The emphasis is on educating the kids and those around them.
"The Biggest Loser" has its season premiere on NBC 5 Sunday night at 9, before moving into its new home Mondays at 8 the next night.
