Season 10 kicks off with a new theme of paying it forward and 21 contestant hopefuls vying for a spot at the ranch. 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. 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. Those who don't make it will get a chance to vie for a spot on the show in a later episode.

The fourteen contestants learn that they will be joined on the ranch by two of the seven eliminated contestants, those two being saved, one each by Bob and Jillian. They also learn that despite wearing a same colored t-shirt as the other contestant that made it through from their city, each of the sixteen contestants is competing as an individual. The sixteen go through their first workout with Bob and Jillian, and have their first assessment by Dr. Huizenga. Both processes are eye opening experiences, and not in good ways for most. Bob and Jillian also take the contestants into the kitchen to discuss their diet, past and future. Aaron, Brendan and Mark receive presents from home based on the discussions in the kitchen. Alison drops two bombshells on the contestants regarding their first weigh-in on the ranch: it will done earlier than they expected, and the yellow line will not be above the bottom two contestants but rather the bottom half of all the contestants. Although most ... Written by Huggo

With Allie being voted off the ranch at the last weigh-in, there are fifteen contestants remaining at the ranch. At that last weigh-in, seven of the eight women were below the yellow line, and as such Jillian feels the women have to get out of what she calls their kum-ba-yah mentality. That overwhelming atmosphere of bonding and friendship amongst all sixteen contestants has now disappeared with the first elimination, which makes them all truly realize that they are in a competition, however a competition in which two of the remaining fifteen express not wanting to participate, which raises the ire in the remaining thirteen and in Bob. Because of the twists demonstrated in the past week, the trainers are now treating every workout as a last chance workout as no one is aware when the weigh-in will happen. One of those workouts is provided by tennis player Anna Kournikova. The contestants participate in an immunity reward challenge inspired by Anna's visit. That challenge piques the ...

With Tina voted off the ranch after the last weigh-in, there are fourteen remaining contestants, who learn that there will be two lines this week, a half group yellow line, and a one person red line, that person being the contestant with the lowest percentage of weight loss and who will immediately be leaving the ranch. These two lines mean that two people will be going home this week. This news makes the reward temptation challenge all the more important for those that either feel the need for the reward based on low percentage of weight loss in previous weeks, or want the perceived power. The reward is a one pound advantage coupon that grows by one pound each week that it is not used. As the temptation was cupcakes, chef Curtis Stone teaches the contestants how to make low calorie cupcakes. The contestants are once again surprised by a mid-week weigh-in. After the weigh-in, Jillian takes aside one contestant who hasn't yet felt an emotional breakthrough despite having consistently ... Written by Huggo

With Sophie being below the red line and Burgandy the person voted off of those below the yellow line after the last weigh-in, there are twelve contestants left on campus... or so those twelve believe. However, the five contestants who never made it onto the ranch arrive, with the one of those five with the highest percentage of weight loss coming onto campus to compete with the twelve. That person learns that he/she will wield much power as that person will also determine the newly formed teams: six on the black team who will train with Jillian, and six on the blue team who will train with Bob, with the final person, who will have immunity for the week, being allocated to the team who loses a contestant this week. That person makes a surprise decision which may be their downfall if the plotting on the ranch works the way those contestants determine. The game playing irks Bob and Jillian, who get wind of the plot. Beyond their first workout, their first team task is a reward challenge... Written by Huggo

Immediately following the latest weigh-in when Rick was voted off campus, Alison tells the remaining twelve contestants that at the next weigh-in, only one person's weight will count from each team, that person to be chosen by the opposing team at the weigh-in. This scenario places extra pressure on every single person as the potential one from their team whose weight will count. As such, both Bob and Jillian work their respective team harder than usual, with neither tolerating fits of drama as some contestants are apt to do when they don't want to work hard. Their pop challenge involves cooking with chefs Curtis Stone and Lorena Garcia, where three from each team will, with the assistance of one of the chefs, prepare a dish apiece for the remaining six to judge, with the team with the highest overall judged dishes winning a mysterious advantage at the upcoming team challenge. The catches are that the others won't know who cooked what, and neither Chef Curtis or Chef Lorena are ... Written by Huggo

Immediately following the latest weigh-in when Adam was voted off the ranch, the remaining eleven contestants learn that they will immediately leave for their new training site to work with their new trainers for the week: Camp Pendleton with the US Marine Corps. Upon arrival at camp, some are buoyed by the discipline they feel they require to achieve their weight loss goal, while others feel they can't handle the boot camp style of training. They learn that everything they do, part of the marine code, is to work as a team and never to leave one of their team behind. Their first task is to hike with full gear to their barracks. Their team challenge for the week is to complete an obstacle course as a team, each member having a thirty pound pack on their back, which they can redistribute amongst their team members as the team sees fit. The winning and losing team are only as strong as their weakest team member. The winning team's reward is telephone calls from home. Bob and Jillian ... Written by Huggo

After Anna is voted off the ranch at the latest weigh-in, the trainers are dismayed that it was collectively the worst weigh-in in the show's history with three of the contestants gaining weight. The remaining ten contestants learn that for the next week they will no longer be in two teams, but rather five teams of two, each pair who will weigh-in together. Two teams will fall below the yellow line, with one team being voted off the ranch. One of those ten will make the decision as to the pairings based on a temptation challenge where on a set menu, each contestant will secretly order an appetizer, a main course and a dessert apiece, with the person consuming the most calories winning the challenge. For the food to count toward the calorie count, the entire plate of food must be consumed. When the appetizers arrive, it becomes obvious who is playing the game. What may be more troubling is the one person not playing the game that decides to eat a decadent dessert just for the want of ... Written by Huggo

Bob vents his frustration out on those who voted Aaron and Jesse off campus after the latest weigh-in. The eight remaining contestants, now competing as individuals, are provided support in the form of video messages from home. One contestant, however, receives no such traditional support, but does receive one from a non-traditional source. Both Bob and Jillian focus much of their attention on Elizabeth, who they feel has not yet been able to stand on her own two feet at the ranch. Jillian gets her to complete a yet as of unfinished task. But they want all the contestants to step their training up a notch as their on-ranch journey gets closer to ending. The reward challenge for the week is a one foot balancing one while perched precariously over a pool of water, the winner to receive a one pound advantage at the weigh-in. The one pound becomes all the more important when the contestants learn what will be happening the following week if they remain on the ranch. Written by Huggo

Their most exciting moment may be revealing their new selves to their family and friends. Ada continues to deal with the issue of lack of support from her family. Back to the game, the contestants' reward challenge for the week is to ascend the 300 foot long Angel's Flight funicular either by the train, which is worth one point, or by foot, which is worth five points. The first contestant to 100 points wins the challenge and a new car. The challenge has a surprise ending, and one contestant feels let down by not completing the race. Bob offers that ...
