The Biggest Loser - Season 18

Twelve people who want to get healthy and transform their lives arrive at 'The Biggest Loser Campus.'

A loss by one team causes emotions to run high as the contestants push harder to meet their goals.

Two contestants overcome their insecurities and emerge as leaders during this week's challenge.

All the remaining contestants finally get to reconnect with friends and family.

The contestants take a dive into fitness as friendships grow stronger.

One contestant faces an unexpected obstacle, forcing their team to come together in new ways.

There are six contestants left—and no more teams. Everyone is wearing the same uniform now. That means they also have to hold themselves that much more accountable for every minute, every rep, every calorie, every challenge, every pound if they intend to stay any longer. Just when you think they've been pushed to the brink, think again. This burn is going to turn into an inferno.

The contestants get the encouragement they need to keep going forward on their adventure.

The final four contestants revisit a fitness milestone to see how much progress they have made.

All twelve contestants return to The Biggest Loser campus for one final weigh-in, to see where they've come since they started. One person will win $100,000 and the title of The Biggest Loser. One of the eliminated contestants will win the $25,000 At-Home Prize.
