A new twist is in store for fans of "The Biggest Loser" when the show comes back for Season 13. The pairs participating in the new season will compete against one another instead of as a team.
The couples, including parents and kids, spouses, siblings and friends, won't find this out until they arrive at "The Biggest Loser" ranch. And in another twist, one couple won't make it to the ranch. "The Biggest Loser: No Excuses" kicks off Tues., Jan. 3 at 8 p.m. ET on NBC.
