'Biggest Loser' Ups the Ante with Face-Offs

The ante has been raised in this week's The Biggest Loser as emotions run high with face-off challenges in the gym.

Trainer Bob Harper gets stern with the black team and brings the competition up "a whole other notch."

Winners of a challenge pour out their emotions as they are allowed to communicate with family members over video chat, reflecting on how much they've missed their loved ones.

Then, red team trainer Dolvett Quince raises the stakes for a team workout by making the loser of a face-off buy lunch for the winner.

One player will make a shocking decision that bewilders everyone before another contestant is sent packing after the weigh-in.

Check out the all-new The Biggest Loser episode tonight (Tues.) on NBC.
