Exclusive Video: Michelle Obama Sizes Up Biggest Loser's Kim, Calls Her an 'Inspiration'

In Part 2 of The Biggest Loser‘s makeover episode (airing Tuesday at 8/7c, on NBC), the weight-loss competition’s contestants get sized up by no less than First Lady Michelle Obama — and we’ve got an exclusive first look at one of the emotional encounters.

As seen in the clip below, FLOTUS tells Kim Nielsen, a 38-year-old single mom of three (and onetime WWE wrestler) who entered TBL at 252 lbs., that her dramatic transformation is an “inspiration,” one in keeping with the initiatives Obama backs, such as PALA (the Presidential Active Lifestyle Award), a pledge-based program designed to get adults and kids more physically active, and Let’s Move!, which is focused on solving childhood obesity.

Later in the episode, 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.
