The competition heats up as host Alison Sweeney tells the remaining seven players that they will be competing in a pentathlon -- and they can only rely on themselves because this week, the game goes to singles. Contestants will earn points in each of the five events, which will test everything from speed to strength to nutrition knowledge. The pentathlon winner gets the coveted prize of immunity, while the loser gets a weigh-in disadvantage. The players get a very special surprise when eight-time Olympic medalist Apolo Ohno arrives to lead the contestants through their final event, motivating them each step of the way. Also, one of the trainers reveals details about their difficult childhood to a contestant who is struggling with trust issues. And later, the weigh-in is followed by the most emotional elimination of the season so far.

It's a NFL week at the ranch, and the competition to be the Biggest Loser of the week is fiercer than ever with the weigh-in winner getting an amazing prize -- a VIP trip for two to the Super Bowl! Host Alison Sweeney reminds the contestants that if they want to be the best, they have to beat the best at a football throwing challenge in which they compete alongside Green Bay Packers linebacker Clay Matthews, New Orleans Saints quarterback Drew Brees and Atlanta Falcons tight end Tony Gonzalez. One player really struggles emotionally this week, while another remains determined despite being partially sidelined with an injury. There's a grueling, calorie-burning competition among the three teams led by trainers Bob Harper, Anna Kournikova and Dolvett Quince. And later, Denver Broncos quarterback Tim Tebow, Buffalo Bills linebacker Shawne Merriman and Hall of Famer Eric Dickerson help put the contestants through last chance workouts they'll never forget before a tense weigh-in reveals which player gets the coveted Super Bowl tickets.

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. Alison Sweeney hosts the series.

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. Alison Sweeney hosts the series.

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. Host Alison Sweeney stars along with trainers Bob Harper, Anna Kournikova and Dolvett Quince.

The competition shakes up this week when contestants change teams and trainers in a high-stakes, calorie-counting challenge that will determine who each player's trainer will be for the rest of the season. After the teams are re-aligned, dramatic confrontations follow between some players and trainers as they all try to adjust to their new reality. Later, the new teams face their first challenge together -- racing down a water slide on a hill to unscramble block letters that reveal the winning team's prize. Trainers Bob Harper, Anna Kournikova and Dolvett Quince each take their teams off the ranch to spice up their last chance workouts, and later, an especially emotional elimination follows a weigh-in revealing noteworthy results from the trainer/team switch.
