This week, contestants are surprised by the return of the blue and yellow teams, who were sent home after the first challenge of the season. Now they’re back, 30 days later, to weigh in and try to earn a spot back on the ranch. Then a vigorous football challenge tests everyone’s stamina, except for one player sidelined with medical issues, and provides immunity for the winner – but a big disadvantage for the losing team. Later, after another elimination round sends a player home, host Alison Sweeney surprises the contestants with exciting news.

It’s a star-studded Olympic-themed episode of “The Biggest Loser: Couples” to help kick off the winter games! This week, the contestants head to Colorado to train like Olympic athletes at the U.S. Olympic training facility in Colorado Springs.

This week's first challenge is a temptation with, literally, hundreds of cookies. Ali tells the teams that whoever wins this temptation challenge will get a huge reward: they'll be able to divide everyone into the two traditional teams, Blue and Black. Also, they could give one contestant immunity from this week's elimination. Let the games begin!

The teams pull trucks and load crates onto the vehicles for a challenge that ends with a puzzle. Later, the contestants work eight-hour shifts at the food bank and must learn to fit workout sessions into their schedules.

The 16 players have been chosen and head to The Biggest Loser Ranch. The theme this season is second chances. The contestants are happy to finally meet Bob and Jillian, but are a little surprised when the bus drops them off at the beach to meet with Ali first.

Tracey tries to protect herself and Coach Mo by making controversial decisions that end up antagonizing the other players and frustrating her trainers. A temptation gives one player control of the game and the Challenge offers immunity. When two teams fall below the yellow line, one team sacrifices itself for the other.

Ali reveals to the contestants that two people will be going home, but there's a second twist. In addition to the yellow line, there will also be a red line. Whoever falls below the red line will be automatically eliminated and sent home prior to the voting. This causes tension between two players.

This week is makeover week, and each contestant is made over with the assistance of Tim Gunn and Tabatha Coffey. They then give speeches designed to inspire and motivate others.

Investment guru Suze Orman, makes a guest appearance on the show to advise the contestants and to administer a quiz. She says she is there to help them find the balance between health and wealth. She tells them that obesity is a very expensive disease. She asks them financial questions relating to health and weight.

The contestants all go home for 60 days, in which they have to find time to balance time with their families, their jobs, and find time to work out. Each player gets a phone call from either Bob or Jillian, explaining that they are going to run a marathon.

The wait is finally over! The live finale has arrived. Who will win that $100,000 prize?

The season premiere kicks off with the contestants arriving at the ranch in teams of two, including mother/daughter, father/son, sisters, best friends, grandparents, cousins, an engaged couple and former models. Included among them are the series' oldest players yet (63-year-old grandparents), youngest male contestant (18), heaviest female contestant (379 lbs.) and heaviest contestant ever in the history of the show (454 lbs.). Alison Sweeney hosts and trainers Bob Harper and Jillian Michaels return to train the 11 couples who begin the show with a combined weight of more than 3.5 tons.

This week, the contestants are faced with a temptation that will cause each of them to examine the real reason they've come to the ranch. Then it's off to an outdoor challenge, where they'll race by sea kayak and then on foot to the top of a mountain, hoping to win immunity as well as a coveted phone call home. Later, one contestant pushes trainer Bob Harper to the limit, causing him to freak out during last chance workouts before a surprising weigh-in leads to a heartbreaking elimination.

This week kicks off with a temptation that host Alison Sweeney tells the contestants will allow one player to reunite with their teammate at home and bring their trainer with them. But the reunion doesn't go exactly as planned when fireworks erupt between the two teammates after one player accuses the other of not doing all she can to stay on the ranch. Meanwhile, the contestants check in with Dr. Huizenga to see how far they've come and how many medications they no longer need from the first three weeks of weight loss. Then a wild jump rope-like challenge results in immunity at this week's weigh-in for the winner, followed by a surprising elimination that sends another contestant packing.

It's Super Bowl week on the Biggest Loser ranch, and that means food, football and fun with two special guest stars - celebrity chef Curtis Stone and NFL MVP Kurt Warner. First, Stone tests the contestants' calorie knowledge of traditional Super Bowl snacks, then teaches them how to make healthier versions. Later, one contestant has to leave the ranch for a very important arrival at home, while another surprises her teammates with a new change in attitude. Then it's time for the challenge, when Warner puts the contestants through an NFL-style drill that will give the winner an especially valuable prize this week. Then the partners who were sent home for 30 days while their teammates stayed on the ranch are welcomed back. But the reunion celebration is quickly followed by a tense weigh-in and elimination that will leave one team heading home.

Now that the contestants' partners are back at the ranch, those who've been working out at home will weigh in and see how they have fared away from the ranch. Then all the players compete in this week's "rope challenge," and later, an elimination leads to tension on one team when one player thinks her partner hasn't been pulling her weight.

This week, the contestants hike up a hill to find over 100 keys, but only two teams will find the keys that unlock the Biggest Loser gym. The rest of the teams have to learn to creatively work out all week without the use of the gym. Later, a rowing machine challenge pits team against team, and then a surprising turn of events leads to one contestant heading home.

This week brings a shake-up no one sees coming when all of the contestants are divided into just two teams, blue and black, leaving many players without their original trainer. Drama ensues, especially with one team who struggles to get used to their new trainer. And contestants are put to the test with one of the longest challenges ever, in which each team tries to put as many miles as they can on their bike in a 24-hour period.

In part two of this week's two-part episode, the contestants continue to adjust to their newly formed blue and black teams.

Then it's time to visit Dr. Huizenga for a progress report and to find out their new "real ages" now that they've lost so much weight. The players also try on their "goal outfits" and are amazed to see how far they've really come. Then after weighing in and eliminating one more contestant, the final four players head home, where they'll stay for 30 days before returning to weigh in at the ranch one last time.

The final four contestants go home for 30 days, reunite with friends and family and experience firsthand the challenge of continuing to make diet and exercise a priority back at home. Contestants also learn from host Alison Sweeney what their final challenge of the season will be - running a full marathon when they return to the ranch for their final weigh-in. Completing the full 26.2 mile course will be their toughest challenge yet, but cheering them on along the way are some past season "Biggest Losers"- grand prize winners Ali Vincent and Michelle Aguilar, plus "at home" winners Jim Germanakos, Heba Salama and Bernie Salazar. And as an added incentive, each player who finishes the marathon will get $10,000 to donate to the charity of their choice. Later, it's the very last "last chance workouts" with trainers Bob Harper and Jillian Michaels before a final weigh in determines who the two definite finalists will be - and which two contestants fall below the dreaded yellow line, leaving America to vote which one will be the third finalist to compete for the grand prize of $250,000.

But this is no vacation, as the contestants must eat and exercise without the help of their trainers and with all of the distractions and temptations of the real world. After returning to the ranch, the teams face off in a challenge that tests their endurance before an elimination round sends another player packing.

The competition heats up as only eight players remain. One team is surprised with a special trip to Las Vegas, but will they maintain their diets and workouts in Sin City, or give in to temptation? Then, in a very emotional elimination, one unsuspecting player makes the ultimate sacrifice for their team.

After revisiting the hospital to check in on their progress, the remaining players face off in one of the biggest challenges in "Biggest Loser" history -- they must fly across a ravine on zip-lines and collect flags. One player gets the chance to give immunity to himself or one of his teammates, and his decision ultimately affects his own fate. And a shocking announcement at the weigh-in changes the way the rest of the game will be played.

Celebrity Chef Rocco DiSpirito visits again to teach the contestants how to make healthy versions of their favorite dishes before heading home, and the final four all watch videos of their most memorable moments on campus. At the weigh-in, two of the four players fall below the yellow line, but there's one last surprising twist. For the first time ever in Biggest Loser history, America will determine who the third finalist will be by voting online on the two that fall below the yellow line. Who they choose to be a finalist - and who they choose to eliminate - will be revealed at the live finale on April 15.

In this must-see, exciting live finale, all of The Biggest Loser contestants from this season return for a special reunion and a chance to weigh in one last time and show America how much weight they've all lost since beginning their weight-loss journeys. There are four contestants left, but America has voted on the two that fell below the yellow line in last week's episode to choose who will be the third finalist in the game. After America's vote is revealed and the third finalist is announced, the eliminated player will then weigh in with the other 16 eliminated contestants to compete for the $100,000 "at home" prize. Then it's the moment viewers have been waiting for, when one of the three finalists will be named this season's "Biggest Loser" and win the coveted grand prize of $250,000.

The contestants start off their weight-loss journey by being dropped off in the middle of the desert, while their trainers standby about a mile away from them. The first two to reach their trainers will become the team captains, allowing them to pick their five teammates. However, this means the six remaining contestants have to be sent home, but Jillian Michaels returns to let them in on a little secret.

Bob and Kim prepare their teams for this week's challenge: racing up the stairs of a 10-story building. With immunity as the prize, both teams will have to do their best. Meanwhile, the secret black team, trained by Jillian Michaels, is finally revealed to the other contestants, who will join them in competing for the title of "The Biggest Loser" and $250,000.

When the teams are put in a room full of tempting, unhealthy foods, they will have to decide in four minutes if it is worth it or not to eat the most calories in order to win a three-pound pass which can be used to their advantage at the weigh-in. In the challenge, the contestants will compete in three different 100-meter heats against a yellow team formed by three kids, where the winning team will win a phone call home.

Another food temptation this week puts the trainers to the test instead of the contestants. Should Bob, Kim or Jillian give in to the temptation, it will give their team a 15-second advantage in the physical challenge. The challenge consists of the contestants running up and down a hill to reach their team flag in the fastest time. However, there is one catch: the teams will have to outbid each other with a faster time in hopes that someone will wager lower and lose, which will end up knocking out a team.

Alison surprises all three teams with an exotic getaway vacation, but they soon learn that they will be faced with temptations and challenges unlike any they have faced at the campus. Later, after the weigh-in, those who lost will try to forge an alliance with the others before deciding who to vote off.

Caroline Rhea hosts the live season finale, where ""The Biggest Loser"" will be chosen out of the three remaining contestants. The results of all their hard work will finally be revealed, with ""The Biggest Loser"" also walking away with $250,000, as well as a healthier lifestyle.

In a life-altering competition, contestants use medically approved weight-loss techniques to shed pounds and try to win a $250,000 prize. The twelve players are seperated into teams - red and blue - and in the first challenge, pulling a heavy car across a track - the Blue Team prospers, but despite their advantage, the Blue Team also loses the least amount of weight at the weigh-in, and Dana becomes the first to be voted out.

After a tough elimination, the Blue Team gets back into the game on the second challenge, a bake-off which will determine the winner of a luxorious spa visit. The catch is that if any player takes a taste of anything they bake, 50 percent of all profits their team made is not counted. At the end of the task, the Red Team pulled through, making $362, edging out the Blue Team's $245. More importantly, the player's will power held strong, and no one took a lick of any food. At an emotional weigh-in, where neither Maurice, Lizzeth, Dave or Matt lose any weight, the Red Team is sent to the elimination ceremony, where Lizzeth is sent packing.

The Red Team and the Blue Team are forced to go onstage and perform about their feelings on their weight and weight-loss. The winner, decided by the audience at the nightclub which the players performed at, is the Red Team, who is given a reward. Later, even with the Blue Team training as hard as ever, the Red Team loses more weight than the Blue Team, forcing Blue to the elimination ceremony, where rumours and whispers divide their team. The deciding vote comes down to one of the Blue Team members, and Aaron is eliminated.

""Red and Blue Teams Go to New Heights"" - Blue Team trainer Bob Harper seems surprised after Aaron's ouster the night before. Things move on at the ranch, and after a workout, the players find a giant mountain of cupcakes in the house, with a note saying that whichever player eats the most cupcakes in 15 minutes would get to eat dinner with a loved one. After deciding on a method where no one would eat too many calories, Dave eats only one cupcake and is able to eat dinner with his wife, Tina. At the challenge, teams are forced to run up 1,500 steps to the top of a huge building. The Blue Team completes it more quickly than the Red Team, and are given a great reward. After a spat between Lisa and Jillian about effort, the weigh-in reveals that the Blue Team had lost more weight than the Red Team, and in the end, the Red Team chooses to send home Matt because of his failure to work with the team.

""A Team Lightens Up Through Elimination"" - After Matt's elimination Ryan realizes that Dave has been lying to him and the girls of the Red Team for the entire game. The challenge of the week is a food stacking competition - where team members must build their stack the highest using only their mouths and they may not eat any of the food during the game. The Red Team emerges victorious, giving them an amazing reward. However, the Blue Team comes out as the biggest winners; Andrea's 7-pound loss pushes their team to victory at the weigh-in, eventually leading to the Red Team eliminating the team member that is most annoying: Dave.

""Teams Trek to the Beach for a Challenge"" Rumours and suspicions fly after a tense previous elimination, where the women in the house assumed that the men were trying to pick them off. Players are just starting to get on each other's nerves: Maurice's lack of work ethic angers his team - and his trainer, Kelly Mac's backhanded compliments annoy the Red Team, and Lisa's whining continues to get on everyone's nerves. At the challenge, an agility competition meant to mimic lifegaurding, the Red Team prospers, winning themselves a trip to the Umberto Salon, where they receive makeovers and new hairstyles. The Blue Team, forced to vote one of their own off of the ranch, cannot decide who to eliminate. With a deadlocked vote, the members of the Red Team must choose to eliminate one of the members of the Blue Team, finally deciding on Kelly Mac.

""Biking Challenge"" Contestants race to log the most miles on a stationary bike before midnight, with a prize of better-fitting clothes as an incentive; participants learn of a new twist in the game.

The contestants are given an overwhelming surprise when they come face-to-face with their old, bigger, selves - cardboard cutouts as they apperaed the first day they arrived. The players run around a track with a weighted vest carrying the weight that each has lost so far. Ryan comes closest to his time from a previous run, winning himself immunity. At the weigh-in, Maurice and Lisa find themselves eligible for elimination, and when the other players vote, Ryan betrays his pinky promise with Lisa by being the swing vote for her ticket out of the house.

""A Lighter Side"" An often-comic look at the first eight episodes; previously unseen footage of contestants' exit interviews; bloopers; the contestants who cheated when they thought the cameras were out of range.

""Final Weigh-In at the Ranch"" It's payback time as the contestants turn the tables and ""train"" the trainers. This episode is the final weigh in at the ranch, preceded by the contestants reflecting on this journey that has changed their lives, and followed by a vote to trim the players' numbers down to three.
