Beyonce Knowles officially joined Michelle Obama’s “Let’s Move” campaign on Wednesday with the release of her music/exercise video, “Move Your Body”.

She throws her towel in the ring in the fight against childhood obesity following the likes of Ellen Degeneres and Jamie Oliver – celebrities who have also used their star power and influence to bring light to this important issue. The video takes place in a busy school cafeteria cum dance floor. Beyonce sings flanked by student backup dancers. The “move your body” message and school lunch atmosphere effectively show the dual importance of physical activity and a healthy diet in combating obesity.
