On Tuesday, May 3, 2011 at 1:42 p.m. Eastern Time and across time zones, middle schools across the country will participate in the "Let's Move! Flash Workout." This historic event is being produced in support of First Lady Michelle Obama's Let's Move! initiative and will underscore the importance of physical activity as part of a healthy lifestyle for children. Music superstar Beyonce is the exclusive featured artist for the Flash Workout event. Beyonce has re-written and re-recorded one of her songs with a Let's Move! message and has titled it "Move Your Body." She has also provided choreography in an instructional video to help students practice and prepare for event day. The goal is to have as many US middle schools as possible participating in the Flash Workout routine on May 3. Local television and radio stations will cover the event at some of the schools and a viral video will also be created. It is also possible that some of the schools' events will be covered on the broadcast and cable networks. Upload and share your video of the event at your school with the tag: FLASHWORKOUT
