was "a pretty genius move" on Michelle Obama’s part to get Beyoncé in on her 'Let's Move!' campaign to fight childhood obesity. On April 9, 2011, an instructional video featuring a group of teenagers dancing to "Move Your Body" was released online. After a few days, Beyoncé has said that she "would record her own version of the exercise routine" to show kids how it is done by shooting a new music video featuring a series of fun workouts to accompany the track. On April 26, 2011, Beyoncé released a video directed by Melina Matsoukas for "Move Your Body". In the video, students join Beyoncé to perform choreography by Frank Gatson. In the choreography, Beyoncé and the students mix salsa, dancehall, The Running Man, Dougie, stomp. The music video for "Move Your Body" takes place as a four-minute long flash mob. The video begins during lunch hour at what looks like a junior high cafeteria. Everything is normal until Beyoncé, wearing short shorts and green knee-high socks, enters the cafeteria doors to begin the song. After Beyoncé's entry, all the kids jump to their feet, following along as Beyoncé leads the group through all kinds of dances. The instructional video was distributed to participating schools across the country on May 3, 2011, during a 'dance-in'. Beyoncé was at P.S. 161 middle school in Harlem on that particular date. She taught students the moves from her "Move Your Body" video. Beyoncé appeared in the gym much to the delight of her young fans, who danced alongside her and took photos. Lauretta Charlton of Black Entertainment Television (BET) gave the video a positive review stating that "It's impossible to watch without wanting to, well, move your body." Nicole James of MTV Buzzworthy showed great interest in the video and its message, stating that Beyoncé gets kids heart pumping, "in more ways than one". Genevieve Koski of The A.V. Club added that "if anything can help curb the nation's childhood obesity problem, it is the galvanizing power of Beyoncé Knowles dancing", and further praised how "[the] bunch of cute kids [were] doing the Running Man and The Dougie in the cafeteria with Beyoncé." A writer of Rap-Up described Beyoncé's dance moves in the video as "hot". Mike Barthel of The Village Voice described the video as "adorable" and classified it as an "important moment in the relationship between politics and culture". Barthel also
