Episode 901 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 Michaels 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.
Episode 902 This week, Dr. Huizenga delivers the sobering news that this season of contestants is the most unhealthy ever on the show, and more at risk for catastrophic diseases than any previous cast. To illustrate his point, he gives each team a medical task that proves to be a real eye-opener as to what their poor health is really costing them, and how important it is to make healthy changes in their lives. Later, a balance challenge over a pool offers the best prize of all for the winning team, but an unexpected event affects the ending of the competition. Later, trainer Jillian Michaels tries to get one contestant to face one of her biggest fears, and then an elimination after weigh-in sends another contestant packing.
Episode 903 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 theyve learned to their teammates or students, who dont 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.

Trainers Bob Harper and Jillian Michaels invite two Olympians to help work out the contestants - gold medalist skier Julia Mancuso and Jeret "Speedy" Peterson, the freestyle skier famous for his "hurricane" jump.

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.

The winning team gets an amazing prize. Then it's work week for the contestants, with each working eight-hour shifts at the food bank while also fitting in workouts in a specific time frame, a real-world task that proves very challenging for some.

Then popular chef Curtis Stone stops by to help host Alison Sweeney judge a food cook-off challenge.

Then an emotional elimination round sends another player home.
Episode 910 The contestants return to their hometowns to visit family and friends. But with those happy reunions comes the challenge of continuing to eat right and exercise despite all of the distractions and temptations away from the ranch. After arriving home, the players also get a surprise - a gift crate with a stationary bicycle and a DVD of host Alison Sweeney explaining the at-home temptation and challenge that awaits them. Each contestant will ride the length of a full marathon (26.2 miles) on their new stationary bike - but they are also provided with a temptation in the form of 48 mini-cupcakes. For every cupcake a contestant may choose to eat, they can apply five minutes to the final ride time of any other player during the bike challenge - a twist that could have a dramatic impact on the outcome of 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.
Episode 912 The competition heats up when the players learn that whoever loses 2% of their body weight first this week gets immunity.

Later, the players head to the pool for a swimming challenge involving weights. After each contestant finishes the race, they are allowed to go back and help others finish, which proves very revealing about who the players want to stay in the game - and who they don't.

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.
Episode 916 The remaining six contestants get $1,000 shopping sprees at their favorite stores before heading to the salon to meet celebrity hair stylist Jonathan Antin and begin their makeovers.

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.
Episode 918 The final four contestants go home to prepare for a marathon, but some of the players have trouble staying on track when surrounded by all of the distractions of home. And one contestant gets a special visit from chef Curtis Stone. Later, they return to the ranch to run the 26.2 miles, cheered on by family members as well as each of their favorite past season contestants - season 5 winner Ali Vincent, Season 2 winner Matt Hoover, and Season 7 contestants Mike Morelli and Sione Fa. The winner finishes in record time, breaking a "Biggest Loser" marathon record. Then 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.
