Michelle Obama helps break world record for jumping jacks

Michelle Obama has earned her family another place in history. This time, Mrs. Obama will share the honor with more than 300,000 other participants on Sunday who set the record for most people doing jumping jacks in a 24-hour period.

The previous world record was just 20,000.

In a video from the White House, seen below, Mrs. Obama thanked National Geographic Kids and the Guinness Book of World Records, who helped organize the event as part of Obama's Let's Move! initiative to promote physical fitness and healthy eating for children. She also said she hopes that physical fitness will be a priority for the kids who participated.

"More than anything, I want to say, thanks to every single young person who showed that exercise isn't just good for you, but that it's fun too," Mrs. Obama said.

On Sunday, Mrs. Obama led about 400 kids from elementary and middle schools in the Washington area on the South Lawn of the White House. Other jumping jack events were held around the world to reach the world-record mark.
