In part two of the series' biggest makeover episode yet, the six remaining contestants get to meet First Lady Michelle Obama, whose Let's Move! initiative focuses on solving the problem of childhood obesity. The First Lady talks to the contestants about how adult behavior impacts kid behavior, congratulates the contestants on being good examples of health and fitness, and visits with each player and their family members. Then it's time for a workout they'll never forget as trainers Bob Harper and Dolvett Quince lead the First Lady, the contestants and their families through "The Biggest Loser's" first ever White House workout. Mrs. Obama also challenges the contestants with a competition to get more Americans healthy and active. Later, Bob tries to help a player who turns to food for comfort to deal with the stress of worrying about a loved one at home, and Dolvett puts contestants through a scenic last chance workout in front of the U.S. Capitol at the Ulysses S. Grant Memorial. Then their amazing trip to D.C. is over and they return to the ranch to weigh-in before another player is sent home.
