Week 1: "Money Hungry"

First aired January 4, 2016
An all-new The Biggest Loser is back, and Season 17 is all about temptation. Eight couples arrive on the ranch to face the biggest temptations and challenges ever.

Things get serious quickly when their new host, Bob Harper, starts off with their first temptation. Everyone gets on the treadmill and goes at their desired pace. Bob starts off with giving $5,000 to anyone who's willing to push their button. But, once they push the button, they also quit the game. No one budges and he goes up to $10,000, then $20,000. Again, no one budges but contestant Vicki nearly collapses and stops. Bob tells her that she'll be okay and she didn't quit because she never pushed the button; she eventually returns to the treadmill. He makes a final push and offers everyone $25,000 to anyone who wants to quit. Every team resists the cash and earns the right to enter the gym. But it's just the beginning.

When they enter the gym, they are introduced to the two trainers for the season: Jen Widerstrom and Dolvett Quince. Jessie Pavelka didn't return this season. The contestants thought that they could choose their own trainer, but they don't realize that the trainers have been watching them since they got to the ranch and they'll be the one who picks the teams. Dolvett picks the Blue Team, Gray Team, Purple Team, and White Team to support Team Dolvett aka Team Red. That leaves Jen with the Green Team, Orange Team, Pink Team, and Yellow Team to support Team Jen aka Team Black.

For the first official challenge of Season 17, each team picks has to put sacks of money onto a scale which will lower a ladder in downtown Los Angeles. Once the ladder comes down, the team will decide which couple to climb the ladder all the way to top. Team Dolvett picks the WhiteTeam, while Team Jen pick the Green Team. Both teams are neck and neck at first, but Richard and Erin from Team Dolvett beat Team Jen's Hernandez brothers to the top when one of the twins on the other team keeps falling off the ladder. Once they reach the top, they find themselves another money temptation: $40,000 for themselves and quit, or an eight-pound advantage for their team at the weigh-in. They resist the temptation and choose the weigh-in advantage and their team is ecstatic for them.

At the weigh-in, both teams have their respective ups and downs. Team Jen wins the first weigh-in with 5.85% lost and Team Dolvett loses for the first time since his debut on the show with only 4.28% even though they had an 8-pound advantage in the beginning.
