Beyonce debuted her music video "Move Your Body" to fight childhood obesity in support of Michelle Obama's "Let's Move" campaign.
In the video, Beyonce is shown starting a flash mob dance in a junior high cafeteria, leading students through various choreographed dance moves.
"It's all about promoting the benefits of healthy eating and exercise," Beyonce said in her promotional video. "But what we want to do is make it fun by doing something that we all love to do and that's dance."
Since its Tuesday premiere, the video has racked up nearly 1.5 million YouTube hits.
The singer revamped her 2007 hit "Get Me Bodied" for the video, which will be shown at schools as part of an initiative sponsored by the National Association Of Broadcasters, the American Association Of School Administrators, the National Middle School Association, and the National School Boards Association.
The video is in partnership with Mrs. Obama's "Let's Move" campaign, which launched a year ago and along with the video, middle schools are encouraged to upload videos of them doing the workout on the Let's Move! Facebook page. One school from each television market will be chosen for television and radio coverage.
