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

The winner of a challenge will be faced with a potentially game-changing temptation; the contestants participate in a tradition in which they experience putting their weight back on and then losing it again.

The teams compete in a competition where the winner decides who gets to go home for a week from both sides; the teams are broken up and wearing their individual jerseys. After facing their first individual challenge, they get a guys and girl's night out and start to sow some wild oats. Two players are eliminated; one a victim of the red line, and one being voted off after falling below the yellow line.

The teams face a challenge in the form of an obstacle course where the winning team can choose to skype with their families or have the gym to themselves, while the losing team gets what the winning team passes on. Following this challenge, a contestant gets eliminated and then the teams face a big challenge when several players switch teams. Following the switch-up, another contestant gets eliminated at the weigh-in.

Bob Harper, the longtime Biggest Loser trainer who has been with NBC's popular weight-loss series since Season 1, will take on an exciting new role - and have a much bigger presence this season - when he also becomes the host of The Biggest Loser. Harper will continue to offer his training expertise to contestants at various points throughout the season. Dolvett Quince and Jennifer Widerstrom will also be returning for the 17th season, training eight contestant teams of two in an exciting return to team-versus-team competition.

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.
