Beyoncé has teamed up with first lady Michelle Obama and her effort to fight childhood obesity across the country. To help get the word out, Bey recorded a new version of her song "Get Me Bodied," changing the lyrics to "Move Your Body," for the campaign.

The song is a step-by-step flash dance-style workout that combines hip hop, Latin and dancehall moves with traditional exercise. The new video is shot in a school cafeteria where Beyoncé is joined by an army of dancing students taking a lunch break. It's impossible to watch without wanting to, well, move your body. Watch the video at That Grape Juice.

On May 3 the video will be released in middle schools nationwide as part of a “dance-in” organized by Obama's campaign.
