VIDEO: Michelle Obama Vs. Jimmy Fallon In Potato Sack Race

First Lady Michelle Obama is making America healthy again, one late night talk show host at a time. Last week, she brought Jay Leno a tray of nutritious samples, and now she's converted Jimmy Fallon to an exercise guru.

Mrs. Obama appeared on Late Night with Jimmy Fallon to promote her "Let's Move" initiative, designed to alleviate the country's obesity problem with a battery of healthy eating and exercise. On the taped segment, Fallon met Mrs. Obama on her own turf (you know, the White House) to go head-to-head with her in a series of fitness challenges, including push-ups, tug-of-war, dodgeball and — the grand finale — the potato sack race.
