The Biggest Loser (US) Show Summary, Upcoming Episodes and TV Guide

It's the last week on the ranch for the final four contestants, and time to celebrate just how far they've come on their weight loss journeys. They'll return to the Los Angeles Coliseum where their journey began for a challenge requiring them to put all of their lost weight back on and drop it incrementally at 16 stops as they did each week, while running up and down the Coliseum steps. The winner gets a cash prize plus a valuable weigh-in advantage when the stakes have never been higher. The finalists also watch emotional journey packages with their trainers, revisiting the memorable milestones of their time at the ranch. 'Today' show lifestyle and fitness correspondent Jenna Wolfe visits as guest trainer, leading the contestants while pregnant through an intense, 'no excuses' workout, while Bob Harper puts the other three trainers - Dolvett, Jennifer and Jessie - through an intense workout of his own. And season 15 contestant Ruben Studdard appears in a 'Challenge America' segment before the final weigh-in at the ranch reveals the three finalists of season 16 who will be competing for the grand prize of $250,000 and the title of 'The Biggest Loser.'.

The contestant have made it to the fan-favorite makeover week in an exciting episode that also brings game-changing surprises. Fashion expert Tim Gunn and celebrity hairstylist Ken Paves return to create more inspirational transformations, working their makeover magic on the final four ranch contestants as well as the two eliminated players at Comeback Canyon. After the ranch contestants get incredible new looks, they are reunited with their loved ones on a downtown rooftop overlooking Los Angeles. It's a magical night that also features a surprise live performance from popular singer/songwriter Gavin DeGraw, performing his hit solo, 'Fire.' Meanwhile, the made-over Comeback Canyon contestants are treated to emotional reunions with their loved ones separately, 15 weeks after leaving home. And the stakes have never been higher at Comeback Canyon, because this week's weigh-in winner will be joining trainer Bob Harper in his long-awaited, surprise return to the ranch, bringing his Comeback Canyon champ to join the competition. And that's not the only surprise awaiting the contestants at this week's weigh-in.

In the first of two special Hawaii episodes, the remaining six contestants are off on the adventure of a lifetime to the breathtaking island of Kauai. There they'll continue the competition and do everything they can to avoid falling below this week's red line. They start their trip at the scenic Waimea Canyon State Park before the trainers put them through an intense workout at Polihale beach. Then, in a Hawaii-style challenge, they all hop into kayaks and paddle out in the ocean to retrieve a bag of puzzle pieces. The finished puzzle reveals the prize for the winner - an incredible, private helicopter tour of Kauai. Later, one trainer and a contestant face their fears together about the open water and try snorkeling, before all the contestants arrive at the beach weigh-in in outrigger canoes to determine who is going home - and who gets to stay in paradise for another week!

This week is all about teamwork as the eight remaining contestants must work together to lose at least 50 pounds collectively so everyone can remain at the ranch for another week. If they don't reach that goal, someone will be going home. A sand pile challenge that requires a big team effort gives the players the opportunity to win a substantial weigh-in advantage. Later, while hiking with their trainers, the contestants take time to celebrate their accomplishments and vocalize their intentions as they move forward on their weight loss journeys. Meanwhile, at Comeback Canyon, two fierce competitors vie for the chance to stay one more week with trainer Bob Harper. One competitor from Comeback Canyon is ultimately sent home, while the ranch scale reveals whether the eight contestants there are safe for another week.

It's the halfway point in the competition and contestants get the exciting news that three NFL legends - Super Bowl champs Michael Irvin, Donald Driver and Willie McGinest - will be joining them this week. First, they'll be part of a football challenge in which a trainer and contestant from each team must catch footballs from the NFL legends - while tied together. And the stakes are high, because the winning team gets the coveted prize of video chats with loved ones. Later, the NFL players join the trainers in the gym and have fun putting their own spin on coaching the contestants. Then a red line at the weigh-in puts all the players on edge, while the Comeback Canyon weigh-in sends another contestant home for good.

A challenge at the beginning of the week causes quite a splash as the red, white and blue teams have to hold a certain percentage of their body weight to keep their trainers from falling into a pool. The team that drops their trainer first loses them for the week, while the team that drops their trainer second will only have their trainer at the last chance workout. While the two teams without their trainers try to rise to the challenge at the ranch, Bob Harper tries to get his two eliminated contestants to work together as a team at Comeback Canyon. And one contestant takes a trip away from the ranch and gives her trainer a glimpse of her 'glory days.' Then a weigh-in full of surprises - including one player reaching 'One-derland' - ends with one contestant falling below the dreaded red line, but thrilled to get a second chance at Comeback Canyon.

All athletes dread the thought of being benched or sidelined from a game, and this week's challenge gives the winning team the power to sideline one player from an opposing team so their weight won't count at the weigh in. And the challenge comes with high anxiety as the players are suspended in the air racing to cross a canyon and put together a puzzle when they're done. Everyone has to step it up this week to avoid the dreaded red line elimination, because they won't know which player is chosen to sit out until they get to the scale. After the weigh-in, the eliminated player is thrilled to learn they have a second chance at Comeback Canyon, while the eliminated contestant at Comeback Canyon heads home for good..

The contestants compete in two challenges this week to gain pound advantages at the weigh-in. The first challenge tests their nutrition knowledge, with their trainers consuming food for each incorrect answer. The 'Wall of Glory' is revealed in the gym, showing contestants when they were top athletes, inspiring them to work ever harder in the gym. Then trainers Dolvett Quince, Jessie Pavelka and Jennifer Widerstrom help out at an endurance challenge before a weigh-in determines who will be headed to the surprise 'Comeback Canyon' location with trainer Bob Harper and which of Bob's two eliminated contestants will be headed home.

Twenty former athletes, including NFL players and Olympic gold medalists, try to change their lives and get healthy on the new season that also features new trainers Jessie Pavelka and Jennifer Widerstrom joining veteran trainers Dolvett Quince and Bob Harper. The contestants are led by former NFL players Scott Mitchell (12 seasons in the NFL) and Damien Woody (two-time Super Bowl champion with the New England Patriots), as well as Olympic gold medalist and former professional tennis star Zina Garrison. Other contestants striving for weight loss include former WNBA standout Vanessa Hayden, three-time Olympic gold medal softball player Lori Harrigan-Mack, and a mix of former college and high school sports standouts. Season 16 also features trainer Bob Harper in an exciting new role, giving contestants a second chance at life on the show. Just when the eliminated contestant each week thinks they are headed home, they will actually be whisked away to a secret location called 'Comeback Canyon.' There they will be trained by Harper, competing at a separate secret weekly weigh-in for the chance to return to the competition and a shot at 'The Biggest Loser' title and $250,000 grand prize.

The stakes are higher than ever when the five final players compete in a 'Biggest Loser' first -- a sprint triathlon, requiring them to swim - a mile, bike 12 miles and run three miles. The triathlon winner will secure a coveted spot as a finalist, as well as a brand new Ford Fusion. Then it's an emotional trip down memory lane as the contestants watch footage of their journeys with their trainers, and see firsthand how far they've come since arriving on the ranch. Later, it's time for the last weigh-in before the finale, where two players will fall below the red line and go home, and two more will become finalists, joining the triathlon winner to compete for $250,000 and the title of 'The Biggest Loser' at the season 15 finale.

The contestants are off on the adventure of a lifetime, headed to Utah Olympic Park in Park City, Utah, where they'll train like champions and get to meet some incredible Olympic athletes. Dolvett introduces the players to Olympic gold medalist Apolo Ohno, who talks about his own 'Second Chance' - this season's theme - and works out with the contestants inside the spectacular Olympic Oval arena. Then the contestants get to compete in the sport of curling, after an introduction to USA Curling team members Jessica Schultz, Debbie McCormick and Anne Swisshelm. The fun continues at the base of the bobsled track, where words of motivation from USA Bobsled Team members Lolo Jones and Jazmine Fenlator get the remaining seven players fired up about the fast-paced sport. But for this week's challenge, they won't be racing down the track. Instead, they will be running more than a mile up the bobsled track, a challenge made far more difficult by the elevation of over 7,000 feet. Also this week, Bob designs an Olympic-inspired workout that puts all the players to the test, and Jillian tries to help a contestant still struggling to embrace her self-worth. Travelling and being away from the ranch environment leaves many contestants worried about their weight loss this week. Those fears intensify at the weigh-in, where surprising results push two players below the yellow line and the other contestants must decide which player is going home.

The 10 remaining contestants reach a milestone this week, as the competition goes from teams to singles. Wearing their new individual color shirts, the players meet host Alison Sweeney for a night-time 'ring of fire' endurance challenge that involves holding a percentage of their individual weights. Alison also shares exciting news about an upcoming event that will be a 'Biggest Loser' first for contestants, and sobering news that this week's weigh-in will end with a double elimination. Now that the teams have been disbanded, trainers Bob, Jillian and Dolvett are eager to switch it up and work out with new contestants this week. One player struggles with self-sabotaging negative thoughts, and two contestants make it to the coveted 'One-derland' at weigh-in and say goodbye to weighing over 200 pounds. Then it's time for the dreaded red line, which will determine which two players will be going home.

Host Alison Sweeney kicks off this week's episode with a shocker - one of the contestants is going home and taking their trainer with them, and their weight will be the only weight that counts for their team when they return in time for the weigh-in. A simple spin of the wheel determine who will be chosen among the players, who would love to reunite with loved ones but are understandably anxious about the intense pressure they'll face trying to lose enough weight to keep their whole team safe another week. Meanwhile, one trainer brings their contestant back to a sport they once loved, and two players celebrate milestones at the weigh-in before another contestant is sent home.

It's a busy week at 'The Biggest Loser' ranch, which kicks off with a fun bouncing ball challenge that will award members of the winning team a welcome cash prize. All of the contestant take an emotional walk down memory lane watching their casting audition videos, reminding them why they are at the ranch -- and how far they've come in just six weeks. Ruben and Dolvett visit music icon and 16-time Grammy Award winner David Foster at his home, where Ruben isn't the only one stepping up to the microphone. And the show's most recent 'Biggest Loser' winner, Danni Allen, stops by for lunch and a pep talk with the contestants. Then it's time for another tense weigh-in, where one more contestant will face elimination.

It's Halloween at the ranch, and that means a pumpkin challenge and the contestants' first temptation of the season. Off the players go into a field of 100 pumpkins filled with candy treats, cash prizes and a winning ticket giving one lucky player one of the biggest prizes ever awarded in a challenge - immunity for their whole team. Later, one trainer brings a special group of people to work out with his team, while another trainer has a heart-to-heart talk with a contestant about their challenging childhood. 'The Biggest Loser' catches up with last season's child ambassador, Biingo, to see how his life - and the lives of his family members - have changed since he was on the show. And later, the players get a motivational boost with coveted letters from home before heading to the weigh-in, where another player is eliminated.

The dreaded 'week 2 curse' is on all the players' minds, especially when they learn that only one person's weight on each of the three teams will count at this week's weigh-in. And they won't know who it is beforehand, only when a roll of the die at the scale determines who will represent the red, white and blue teams. One lucky group will get a weigh-in advantage if they win the first challenge of the season, a water-bucket race that ties each team's fate together in more ways than one. Also this week, one player gets sobering health news from Dr. H, another contestant connects with a very special family member and the show catches up with one of last season's popular child ambassadors to see how they are doing now.

It's down to the final five and the stakes have never been higher. This week, a red line will determine which contestant is going home, and a yellow line will determine which two players America will vote for to determine who the third finalist will be for season 14. But first, the contestants compete for a weigh-in advantage during a 'put their weight back on' challenge, pulling all the weight they have lost up a mountain by sled, and then dropping weights incrementally representing how many pounds they lost each week. Kid participants Biingo, Lindsay and Sunny return to the ranch and see just how far they've come watching videos of their journeys alongside the trainers, and later get an update from child obesity expert and pediatrician Dr. Joanna Dolgoff on their great progress. The adult contestants also watch emotional highlights of their weight loss journeys and get impressive health updates from Dr. H. Then it's time for the last weigh-in on the ranch, determining who is sent home and who the final four players are for season 14.

It's 'Face Your Fears' week, and the fear of leaving the ranch is the first one addressed when a 'save your neighbor' challenge determines which contestant has to leave the ranch and go out on their own for the week - along with another player of their choice. One by one, with the help of trainers Bob, Jillian and Dolvett, each contestant is forced to face their fear - ranging from a fear of sharks to claustrophobia to a fear of singing in public. And they all face fear in a harrowing challenge off the top of a seven-story building that will reward the winner with the most coveted prize of all. Back at home, the kid participants are also facing their fears head on. Sunny's very real fear of losing her Mom due to her mother's weight prompts her to have a very difficult and emotional conversation, while Dolvett arranges for pre-diabetic Lindsay to face her fear of developing the disease by meeting someone with diabetes and learning about their daily challenges. On the lighter side, Biingo faces his fear of eating vegetables! Later, the weigh-in will reveal how the two players out on their own did this week, and will also determine who is leaving the ranch for good, leaving the final five contestants of the season.

It's halfway through the competition, and the remaining eight players go to singles this week. The contestants face their first temptation in honor of Valentine's Day, featuring favorite Valentine's Day treats and the promise of the winner getting a weigh-in-advantage for themselves and a friend. Meanwhile, the trainers continue to motivate the kid participants to stay active and work toward their goals at home. Jillian arranges for Sunny to take a Bollywood dance class, Dolvett motivates Lindsay to attend a cheerleading practice, and Biingo anxiously waits for news from the doctor about whether he'll be able to start practicing for the youth baseball league tryouts that Bob set up for him. Back at the ranch, one player displays an amazing act of kindness, and another has an emotional, heart to heart talk with a trainer about the circumstances leading to his weight gain. Later, a racing challenge leads to two players winning heartwarming reunions with loved ones, and in this week's Challenge America segment, Season 11 winner Olivia Ward and her husband share a healthy way that couples can celebrate Valentine's Day. And finally, the elimination following the weigh-in forces one contestant to make their most difficult choice yet at the ranch.

This week kicks off with the players returning from a workout, only to find that the kitchen and refrigerators are empty. Tasked with trying to affordably stock the kitchen with a week's worth of healthy food, the contestants race against time to make healthy purchases within their budget at a grocery. Later, one contestant struggles to keep trying her best despite weight loss setbacks, while Dr. H and one of the trainers help a contestant realize the importance of addressing the emotional issues that contribute to weight gain. Trainers Bob, Jillian and Dolvett skype with kid participants Biingo, Lindsay and Sunny, and then a swimming challenge puts the players to the test as they compete for one of the most coveted prizes of all. Finally, a tearful elimination sends another player home.

'Cutting the junk' is this week's theme, and the players begin with a trivia challenge testing their knowledge about childhood obesity. The losing team will have to spend 4 hours each day - the amount of time the average kid spends watching TV - in a room surrounded by junk food, soda and video games. Meanwhile, Dr. Joanna Dolgoff, 'The Biggest Loser' childhood obesity expert and pediatrician, travels to the homes of kid participants Sunny, Lindsay and Biingo, to help the kids and their families cut the junk food and get on track with healthy eating. Then it's one of the show's craziest challenges ever when contestants have to race through a gooey bubble gum pit carrying 10 pound balls to win an amazing prize that everyone wants. Later, after a tense weigh-in, the players enter the show's new voting booth to decide which contestant will be going home.

In a season unlike any other, NBC's 'The Biggest Loser' takes on child obesity by featuring kid participants for the first time ever on the show, joining 15 fiercely determined adults eager to lose weight and change their lives forever. The focus for the three kids - 13-year-old baseball enthusiast Biingo, 16-year-old honors student Sunny, and 13-year-old former cheerleader Lindsay -- will be on getting healthy rather than numbers on a scale, so they will not be eligible for elimination and will not weigh in on camera. They will work at both the ranch and at home, and their progress will be featured in every episode. New mother Jillian Michaels is also back, ready to whip contestants into shape with her tough-as-nails, no nonsense approach, alongside returning trainers and top fitness experts Bob Harper and Dolvett Quince. Contestants include a high school special education assistant and mother of four, a former college football player and the show's first openly gay contestant, who was bullied for both his weight and his sexuality when he came out at age 14.

The stakes are higher than ever when all the eliminated contestants return to the ranch to compete in a fateful, four-part challenge. The challenge winner will secure a coveted spot as a finalist, and the chance to compete for the $250,000 grand prize, along with the other two finalists revealed in last week's episode. It's a fight to the finish with each player fiercely determined to get back in the game in a competition that will put their speed, knowledge and endurance to the ultimate test. In the end, the third finalist of season 13 will be revealed.

In part two of the series' biggest makeover episode yet, the six remaining contestants get to meet First Lady Michelle Obama, whose Let's Move! initiative focuses on solving the problem of childhood obesity. The First Lady talks to the contestants about how adult behavior impacts kid behavior, congratulates the contestants on being good examples of health and fitness, and visits with each player and their family members. Then it's time for a workout they'll never forget as trainers Bob Harper and Dolvett Quince lead the First Lady, the contestants and their families through 'The Biggest Loser's' first ever White House workout. Mrs. Obama also challenges the contestants with a competition to get more Americans healthy and active. Later, Bob tries to help a player who turns to food for comfort to deal with the stress of worrying about a loved one at home, and Dolvett puts contestants through a scenic last chance workout in front of the U.S. Capitol at the Ulysses S. Grant Memorial. Then their amazing trip to D.C. is over and they return to the ranch to weigh-in before another player is sent home.

The stakes are higher than ever when all the contestants return to the same spot where they had their first challenge to compete in a marathon. For the first time in the show's history, the contestant who wins the race automatically becomes a finalist, eligible to compete for the $250,000 grand prize. But there's extra incentive because the first five players who finish the race will also get to split $50,000. The only way to guarantee a spot in the finals is to either win the marathon - or be one of the contestants who stay above the red line at the weigh-in. In the end, the three finalists of season 12 will be revealed.

The contestants start their week with a holiday food temptation involving Thanksgiving favorites and amazing prizes, including a coveted 3 lb. advantage. Later, trainers Bob Harper, Anna Kournikova and Dolvett Quince prepare a healthy Thanksgiving dinner for the players, and everyone shares what they are most thankful for, with one trainer sharing a surprising revelation. Then it's the toughest challenge of the season so far with an outdoor, one-mile high climb on Jacob's Ladder treadmill climbers. The top finishers win special prizes with a 'Pay it forward' twist. Later, one contestant does something considered uncharitable by the others, leading to friction at the elimination table before another player is sent home.

This week, only one contestant's weight will count for each team, and trainers Bob Harper, Anna Kournikova and Dolvett Quince get to choose which player will represent their teams. The competition heats up with a cooking challenge in which players and their trainers have to race against the clock to prepare a healthy and delicious low-calorie dish for two special judges - season 11 'Biggest Loser' winner Olivia Ward and 'Biggest Loser' cookbook author Devin Alexander. Prizes for the winning team include something very special from home. Dr. Huizenga drops by with a special medical guest to visit with the players and give one contestant some very welcome news. And later, the weigh-in reveals whether each trainer chose the right person to represent their team before an elimination leaves one player feeling very betrayed.

For Halloween, the contestants face a crazy candy temptation and a very spooky challenge, while host Alison Sweeney and trainers Bob Harper, Anna Kournikova and Dolvett Quince get in the spirit by dressing up in Halloween costumes. First, the contestants learn they'll all be playing as one team this week and if they collectively lose 100 lbs., everyone will be safe for another week. A cauldron of candy hanging on a Biggest Loser scale tempts the players all week in more ways than one - for every pound of candy eaten, a pound will be deducted from the amount they all need to lose, up to 10 lbs. This week's challenge finds players racing through a haunted maze trying to collect as many apples as possible, with another weigh-in advantage - and disadvantage - hanging over them. With the trainers working out all of the players this week, one contestant has separation anxiety, and one trainer is not amused when the contestants play a Halloween trick on him. Plus, a big secret shared by two contestants is revealed. Later, one player ties a Biggest Loser record on the scale before another contestant is sent home.

This week, the contestants are surprised by three special guests - past season contestants Hannah Curlee, Adam Hurtado and Marci Crozier, who each visit and inspire the team that represents his or her respective age group. Then all the players are off to a wild weather challenge in which they have to race while battling the elements - including wind, rain and snow - to win coveted letters from home. The winning team receives an unexpected and very emotional bonus prize. Later, trainer Bob Harper takes his team to the pool for last chance workouts, where one player tries to overcome his fear of the water, while trainer Dolvett Quince pushes his team to new heights in the gym and trainer Anna Kournikova takes her team to a favorite spot - the new 'Biggest Loser' tennis court. In the end, the losing team at this week's weigh-in must decide who will be going home.

This week, the contestants learn that the gym will only be open three times a day, and each team will only have one two-hour time slot daily to work out. A donut temptation will help determine which team gets what slot, and then players have to learn to squeeze in their daily workouts just like in real life. Dr. Huizenga meets with contestants and their trainers for some sobering news about their medical conditions, and one player is shocked to learn what his real inner age is - and that he is the sickest person at the ranch. Then all the teams use their weight to move a ball through a maze over water in a wild challenge that proves to be way harder than it looks. Later, another player is sent home after the weigh-in yields a very surprising number for one contestant.

In this must-see, exciting live finale, the 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 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!.

It's 'Finals week,' and each contestant will be tested by the trainers to see how much they've really learned at 'The Biggest Loser' ranch, with the winner claiming a big cash prize. The players get a chance to add to their overall test scores by competing against each other in four difference exercises while playing 'The Biggest Loser Ultimate Workout' on Kinect for Xbox 360. Later, the contestants are put to another test with a stair-building challenge involving weighted sandbags. The winner gets a weigh-in advantage that could help determine who makes it to the final four - and who is sent home.

It's 'Favorites Week' on the ranch, and the remaining seven players participate in a favorite past season challenge - pulling a car for a half mile. Popular NASCAR driver Clint Bowyer is there to cheer them on at the speedway, and Tara Costa, the season seven winner of this challenge, returns to compete alongside the contestants for some amazing prizes. Later, popular season nine contestant Sam Poueu and season five winner Ali Vincent put the contestants through a workout in the gym, and also motivate the players one-on-one. Then it's a weigh-in full of surprises, leading to one more contestant facing eliminaton.

The nine remaining contestants arrive in New Zealand and embark on the adventure of a lifetime, starting with a visit to Sky Harbor, a popular tourist attraction known for its breathtaking views. Awaiting them are 51 flights of stairs to climb followed by the adrenaline rush of sky-jumping for contestants and trainers. Then it's on to a 5K challenge New Zealand-style, with the winning team getting an unforgettable helicopter ride to gorgeous Waiheke Island. The trainers take contestants to the Auckland Fish Market, where they talk about eating healthy while travelling abroad, and Jillian has a lively lobster encounter. Later, the contestants charter an American Cup racing boat to sail around Auckland Harbor, and one player with a special connection to New Zealand gets a very generous gift.

The remaining four teams square off for a wild pop challenge that involves balancing eggs, and the losing team has to leave the ranch for the week and work with a limited budget to purchase what items they'll need most. Trainer Bob Harper takes his contestants to an inner-city school, where they energize the students with a fun workout and talk about the importance of fitness. Then all the contestants go on a huge Easter egg hunt for 5,000 eggs, including a Golden Egg that comes with a very coveted prize. And later, the players are treated to a sneak preview of the upcoming feature film 'Hop.' Finally, one player reaches a milestone at the weigh-in before another contestant is sent packing.

Host Alison Sweeney tells the remaining 12 contestants that they will all be on one team this week - the blue team - and they will all have immunity if they beat their weight loss from the previous week. But first, there's a pop challenge in which they have to prepare delicious, healthy, low-calorie meals in under 30 minutes. Chefs Curtis Stone and Lorena Garcia will decide who prepares the best dish, with the winner getting a coveted prize. Later the blue team meets at a rock quarry where they'll have to uncover a buried rope attached to signs with trivia questions. If they answer the questions incorrectly, they will be led in the wrong direction, something all the players want to avoid since the winners get a huge advantage at this week's weigh-in. Later, Dr. Huizenga drops by with impressive medical updates, including the news that one contestant has already reached their goal weight. Then it's time for the weigh-in, when players found out if they all get to stay at the ranch another week - or if they'll be sending one contestant home.

The contestants are excited to hear from host Alison Sweeney that they will all be going home for two weeks. Each player returns home to emotional reunions with friends and family, after which they navigate the challenges of being back in their real lives, facing the same temptations that brought them to the ranch and realizing all of the things they are capable of doing now that they couldn't do before. When they come back to the ranch, they'll compete in a 5K challenge on a treadmill just as they did in the first episode of the season, but this time, they're going to run the 5K all by themselves. And just as before, each will pick who they want to train them - Bob Harper and Jillian Michaels or Cara Castronuova and Brett Hoebel - in the order in which they finish the challenge. Then a few contestants reach milestones at the weigh-in, after which another player is sent packing.

The two teams of contestants are all tied up this week - literally - in a rope challenge in which teamwork will determine which group of players will get to use the gym this week, and which team will have to be creative and find other places at the ranch to work out. One trainer moves into the house to try and get a contestant to open up, and later, one team wins the chance to block someone's weight on the scale at a wild physical and mental challenge that finds them pushing a train 800 feet while answering food fact questions along the way. Then one player reaches a milestone at the weigh-in before another contestant is eliminated and sent home.

After four long weeks, the 'unknowns' move to the ranch and are reunited with the other contestants, who get to meet the new trainers for the first time. Host Alison Sweeney explains that the ranch contestants will be safe this week if they collectively lose more than 48 pounds, but for the 'unknowns,' they will be facing their first elimination all season. And both teams only get to see their trainers once this week. The 'unknowns' experience some surprises while settling into their new home, and a secret is revealed about how one contestant has lost so much weight. A challenge involving weights shows which team stacks up to be the best, and later, everyone weighs in and finds out whether one or two players will be going home.

The 'unknown trainers' are finally revealed, and both will share their personal stories that led them to 'The Biggest Loser.' Their contestants, 'the unknowns,' confront one player they feel isn't working hard enough, and later, 'the unknowns' and the ranch contestants square off for a pop challenge. The winning player from each group will get a delicious healthy dinner prepared by Chef Curtis Stone, and compete for a coveted 2 lb. advantage at this week's weigh-in. Later, Dr. Huizenga gives 'the unknowns' startling news about their health, and one player is surprised to learn they have the highest percentage of body fat in the group. Meanwhile, trainers Bob Harper and Jillian Michaels single out a few of their contestants to find out what really led to their weight gain, and then the ranch contestants meet host Alison Sweeney for a water-carrying challenge that will give the winner the sole vote at this week's elimination. Later, a surprising weigh-in -- which results in shocking numbers for one team -- disappoints the trainers in a big way, leading to the elimination of one player they feel isn't ready to go home.

Two new trainers and a compelling new twist deliver a game-changing season like nothing viewers have seen before when season 11 premieres with twenty-two contestants -- eleven family and friend teams of two. After the first challenge, contestants are given the unprecedented opportunity to choose whether to work out with trainers Bob Harper and Jillian Michaels at the ranch - or work out at a secret location with two unknown trainers and get four weeks of immunity. What ensues is a riveting ride of intense emotions, surprising turns and 'can't miss' moments as the two groups fight their weight loss battles separately with two sets of trainers equally committed to giving these players a new lease on a healthier life. The contestants include an Olympic gold medalist, identical twin policemen, a pastor who wants to spare his overweight son from the challenges he faced because of obesity, and a woman who has lost pregnancies because of her weight and wants more than anything to be a mother. Alison Sweeney hosts the series.

The final four contestants leave the ranch and transition back to life at home, showing off their new slimmer selves to family and friends and facing the temptations and challenges of everyday life. Six weeks later, they return to the ranch to run 26.2 miles, cheered on by loved ones. The winner breaks a 'Biggest Loser' marathon record. Then 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.

It's one of the most eagerly anticipated events every season 'The Biggest Loser' makeover episode! First, the remaining seven players head to the salon of celebrity hairstylist Ken Paves, who crafts great new looks for each of them, and then they're off to a People Magazine photo shoot. Later, the contestants show off their stylish and slimmer selves on a fashion runway celebrating Ford Warriors in Pink and all of their efforts to raise breast cancer awareness and fight the disease. Then it's time for emotional reunions when the made-over players show off their incredible new looks to loved ones flown in to help them celebrate their big day. After the makeovers, it's back to reality at the ranch, and then a challenge that will give the lucky winner the biggest prize yet this season -- a 2011 Ford Edge car. The contestants' stamina and endurance are put to the test, but it's their hearts that really come into play when a surprise turn of events at the challenge leads to one of the most heartwarming moments in 'Biggest Loser' history. Finally, one player reaches a milestone at the weigh-in, after which an elimination round sends another contestant home.

Host Alison Sweeney greets players with the news that the black and blue teams are being dissolved, and instead, they'll be competing as pairs this week. A high-calorie dinner temptation will determine who gets to choose the pairs, and the winning contestant's choices for teams creates tension in the house and alienates at least one player who feels betrayed. Trainers Bob Harper and Jillian Michaels work the contestants especially hard this week, and confront a few of the players about issues they can't seem to get past. Later, the pairs compete in a crazy challenge stacking sugar cubes, followed by the most explosive weigh-in yet this season, with heated exchanges taking place among the contestants and the trainers. A surprising elimination follows, sending two more players home.

The contestants start their week hearing surprising news from host Alison Sweeney that at this week's weigh-in, only one person's weight will count for the blue team and the black team. It will be up to the opposing team to decide whose weight will count and the two contestants chosen won't be revealed until the weigh in - leaving the blue and black teams busy strategizing on who they should choose. Then the players get a visit from celebrity chefs Curtis Stone and Lorena Garcia. Each chef is paired with a team to help coach them through a timed cooking competition - but neither chef is allowed to actually touch the food, adding to the tension as they race against the clock to finish in time. The winning team gets an advantage at this week's challenge, a dragon boat race pitting blue team vs. black. It's the ultimate test of teamwork and timing as both teams race to win the challenge and a prize that will give them a valuable advantage at weigh-in.

After hearing from host Alison Sweeney that two people will be going home this week, the contestants face their first temptation in the form of cupcakes, one of which represents a potentially huge prize for the winner that could grow more valuable each week. Later, chef Curtis Stone shows them that desserts can still be part of their lives by teaching them to prepare delicious, low-calorie cupcakes. At an early weigh-in, trainer Jillian Michaels grows frustrated with one contestant who doesn't celebrate her successes, and then trainer Bob Harper invites the players to his house for a vegan meal. Then those who fell below the yellow line face an elimination challenge involving large rolls of carpet, but one player fears elimination when sidelined by an injury. And despite two players being sent home this week, the contestants learn that the competition is about to get bigger.

It's a week of surprises for the contestants, starting with news from host Alison Sweeney that the competition is getting bigger with the addition of two new players who didn't make it to the ranch in the premiere but have been saved by trainers Bob Harper and Jillian Michaels. After all of the contestants get through their first grueling workout, they get eye-opening news from Dr. Huizenga about their health, revelations that are shared with surprise guests. Then the surprise of an early weigh-in - and a twist resulting in more players falling below the yellow line - comes as a shock to all the contestants. Later, they race each other in their first challenge, and then must make a difficult and emotional decision to determine which player will go home first.

This week, the remaining five contestants are surprised by a visit from Dallas Cowboys quarterback Tony Romo, who gives them an inspiring pep talk before taking the players on a hike. They also get a visit from season seven winner Helen Phillips and season three winner Erik Chopin, who talk to them about the challenges and strategies for keeping the weight off once they leave the ranch. A health update with Dr. Huizenga reveals startling visuals of how their bodies look now --inside and out - compared to when they first arrived at the ranch. Then the contestants face what could be their toughest challenge yet - putting all of their weight back on and racing up and down sixteen hills of sand while dropping their weekly weight loss incrementally as it was lost during the season. Later, the final five see just how far they've really come watching emotional videos of each of their weight-loss journeys at the ranch with trainers Bob Harper and Jillian Michaels. Then the five players weigh in, but this time, a red line will determine this season's final four, so whoever has the lowest percentage of weight loss will automatically go home.

It's an exciting week for the remaining seven contestants as they head to Dallas to inspire Texans to get healthy and join them as they run a 5K at the Cotton Bowl. Then it's off to a rodeo for a wild challenge involving wrangling calves that will grant immunity to the lucky winner at this week's weigh-in. And with only seven contestants left, it becomes clearer than ever who is willing to do whatever it takes to be in the final four. Also, season eight fan favorite Abby Rike makes a special appearance this week and invites Jillian to speak at her old high school. Later, back at the ranch, another elimination leaves one player feeling very much alone.

This week's pop challenge finds the contestants piling quarters, each worth $10, on to platters, and then trying to balance the platters as long as they can to win the money they're holding. Aftwards, financial expert Suze Orman talks with the contestants about their financial health, along with season 8 winner Danny Cahill, who she predicted would win last season. It's a wake-up call for many of them struggling with their personal finances, especially when Orman shares her prediction for who will win this season. Then a wild challenge in the pouring rain finds contestants racing to find the right keys that will open this season's biggest prize yet for two lucky contestants - brand new cars! Later, trainer Bob Harper takes the players outside for a workout in the mud, which leads to a wild mud-wrestling fight and a lively chase to bring trainer Jillian Michaels into the fray.

The final nine contestants are delighted to learn from host Alison Sweeney that the game is now going to singles and they'll all compete as individuals for the rest of the competition. Then she reveals a big surprise - the eliminated contestants have returned to try and win a spot back in the game. But for the first time in Biggest Loser history, the player chosen won't be determined by weight loss, but rather by popular vote. After that contestant is voted in, the remaining eliminated players get to battle it out for another spot back in the game - going to whoever wins a 1,000 step-ups challenge. Later, a close friendship starts to unravel, and after a tense weigh-in, another contestant is sent home.

This week, the blue team squares off against the black team in a food trivia pop challenge that will send the winning team via limo to a day of pampering and luxury while the losing team has to stay behind and clean up the kitchen and the gym! Then popular chef Curtis Stone stops by to help host Alison Sweeney judge a food cook-off challenge. Each team has 30 minutes to make an appetizer, entrée and dessert using only 12 ingredients, and the team who wins the taste test gets a big advantage at this week's weigh in. Then an emotional elimination round sends another player home.

After viewers learn who was eliminated after the Olympic challenge cliffhanger from the previous episode, host Alison Sweeney tells all the contestants they are switching to blue vs. black teams. And the winner of this week's temptation will control the fate of all of the contestants, getting to choose which players go on the blue team with trainer Bob Harper and the black team with trainer Jillian Michaels, as well as which player gets immunity. But after proving victorious at the high-calorie temptation that put their memory to the test, the winner quickly finds their game-changing choices alienating several players - and one of the trainers. Later, the newly-formed teams face off on the roof of a very tall building for a pulling challenge that will bring the lucky winners a special prize from home. Then Dr. Huizenga meets with contestants to give them their updated 'Know Your Number' scores revealing how dramatically their health has improved in just seven weeks on othe ranch. Finally, a tense weigh-in pits blue team against black before another player is sent packing.

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.

Host Alison Sweeney surprises the contestants with the news that this will be student/teacher week, with the contestants on each team assuming the role of either teacher or student. The teachers get to continue working out with trainers Bob Harper and Jillian Michaels, but then have to teach what they've learned to their teammates or students, who don't get to work out with the trainers. First, a temptation determines who will decide who the student and teacher are on each team, and later, contestants have to unravel their way through a challenge that grants immunity to the lucky winning team. Also, one player threatens to leave after the trainers try to determine what is causing her negative attitude, and an accusation about game play flies during a tense weigh-in, after which another contestant is sent home.

It is the heaviest cast ever when season nine kicks off with twenty two contestants - eleven family teams of two - coming to The Biggest Loser ranch hoping to transform their bodies, their health and ultimately, their lives. The new season players include Maria and Michael, an Italian mother-son duo who have always put others first while Michael's weight soared to 526 lbs., identical twins James and John, who together weigh close to half a ton, Tongan cousins Sam and Koli, who hope to inspire others in their culture like Sione and Filipe Fa did in season seven, and Cherita, a competitive mother who has already beat cancer and is ready to take on obesity along with her determined daughter, Vicky. Before coming to the ranch, all of the contestants have to weigh in - but for the first time ever, it will be in their hometowns in front of friends, families and neighbors. Then they arrive on campus and are faced with a strenuous bike challenge their first day - and a shocking surprise from host Alison Sweeney.
