michelle obama & juming jacks kids*First lady Michelle Obama is a mover and a shaker.

If she ran for president next year, she might just get elected.

At any rate, Mrs. Obama set a new world record by getting the most people to participate in a day of jumping jacks. She announced Monday that she and 300,265 people participated in becoming the most people doing jumping jacks in a 24-hour period.

The old record is at a mere 20,000 people.

Her goal was to lead some 400 elementary and middle-school students from the capitol in a jumping jacks jump off on the South Lawn of the White House.

The event, which took place on Oct. 11 and 12, was organized by National Geographic Kids magazine, this being the publication’s fifth Guinness World Record.
