Michelle Obama is going all out to help kids get healthy, and she brought in the heavyweights — figuratively, not literally of course — to help her do just that. Dominque, Gabby, Allyson, Bob, Bo, Colin, Sarah, Paul, Serena, and Ashton are some of America's best athletes and they, along with the First Lady, put their dance shoes on to encourage kids to keep moving.
