First lady Michelle Obama participates in the Let's Move! tennis clinic during Day Twelve of the 2011 U.S. Open
First Lady Michelle Obama is not, sadly, attempting a jumping jack world record by herself. But she’s doing the next best thing.
She helping to win the Guinness World Record title for “most people doing jumping jacks in a 24-hour period.” Hundreds of Washington, D.C., schoolchildren will gather with her and do jumping jacks for a minute Tuesday on the South Lawn. (NewsFeed recommends that they blare House of Pain’s “Jump Around” as a soundtrack. And we’ll be there to make the suggestion in person.)
Mrs. Obama is supporting National Geographic Kids, the organization leading the effort to get at least 20,000 doing jumping jacks. But it fits perfectly into her First Lady cause of fighting childhood obesity, notably through her “Let’s Move!” campaign. Other awesome things she has done to this end include getting Beyoncé to produce a workout video and doing the Dougie in public.
