Season 10 kicks off with a new theme of "paying it forward"‘ and 21 contestants vying for a spot at the ranch to get healthy and change their lives forever. With obesity now one of the leading causes of preventable death in the United States, "The Biggest Loser’" wanted to broaden their reach this season, pay it forward and motivate communities -- not just contestants -- to get healthy. So trainers Bob Harper and Jillian Michaels and host Alison Sweeney travel to seven cities in the premiere episode, with each trainer leading community fitness challenges like a one--mile race or a 500 step--up competition. In each of the seven cities -- Detroit, Los Angeles, Portland, Atlanta, Phoenix, Oklahoma City and Boston -- there will also be three contestant hopefuls competing in the challenges. The two candidates who complete their fitness challenge first win a spot at the ranch, while those who don’t make it will get a chance to vie for a spot on the show in a later episode. Guest starring in the premiere will be three popular past season contestants -- season eight winner Danny Cahill, season seven finalist Mike Morelli and season five finalist Mark Kruger.

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.

One contestant expresses a wish to go home this week, creating drama and tension in the house, while another group of players form a secret alliance. Trainer Bob Harper puts the contestants through a grueling workout, zeroing in on one player he thinks has shown him disrespect, and later, trainer Jillian Michaels tries to bring out the athlete in two contestants she thinks need extra attention. Tennis superstar Anna Kournikova gives all the players tennis lessons for a total body workout before a tennis ball pop challenge. Then the players are surprised by another early weigh-in, and those who fall below the yellow line face a wild elimination challenge involving 175 tons of sand before another contestant is sent home. Alison Sweeney and Jillian Michaels also star.

It's the adventure of a lifetime when "The Biggest Loser" contestants are whisked away on military trucks to Camp Pendleton, where they will live and train like Marines for the week. There, they hit the ground running with a fast-paced week of activities led by a select group of Marines. It’s non-stop action, from hiking with oversized backpacks to early morning rifle exercises to an intense obstacle course challenge that pits blue team vs. black, with a prize the players want now more than ever. While some struggle with the physical challenges and the adjustment of being away from the ranch, others thrive, and one even shaves his head to be just like the Marines! Later, the players meet up with trainers Bob Harper and Jillian Michaels at the Camp Pendleton gym for a Marine-style last chance workout, and then a weigh-in full of surprising numbers is followed by another player being eliminated. Host Alison Sweeney also stars.

Five contestants who didn’t make it to the ranch in the premiere episode now return, all vying for a spot back in the competition. Whoever has the highest percentage of weight loss wins their way back in, and also wins one of the most important, game-changing decisions of the season when the competition moves to blue team vs. black team this week. In their first challenge as blue team vs. black, they race through food stations in downtown Los Angeles, answering food trivia questions that come with a physical challenge penalty if they choose the wrong answer. And the stakes are high with the winning team getting "The Biggest Loser" meal plan by Ediets for each member, plus the always-coveted reward of letters from home. When one team proves victorious, members of the losing team get a heartwarming surprise. Later, the drama heats up when a rumor spreads of one team possibly throwing the weigh-in, and after a tense weigh-in, the players send another contestant home. Alison Sweeney hosts the series, and trainers Bob Harper and Jillian Michaels also star.

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.
