Beyonce Lends Some Fancy Footwork to 'Move Your Body' CampaignLast month, Beyonce joined forces with First Lady Michelle Obama to promote the national Let's Move! campaign, which aims to target childhood obesity. The singer offered up a re-worked version of her hit song, 'Single Ladies,' in support of the effort.

The result is 'Move Your Body,' a remixed Swizz Beatz track with lyrics tailored to suit the 'Let's Move! Flash Workout,' video which will be distributed to junior high school students across the country. "It's all about promoting the benefits of healthy eating and exercise," Beyonce explains in the official campaign video. "But what we want to do is make it fun by doing something that we all love to do, and that's dance."
