On Sunday, as part of her national “Let’s Move” project, Michelle Obama is organizing an event in wich she will try to break the world record of Jumping Jacks in a 24-hour period.

Thanks to National Geographic Kids and the Guiness Book of World Records, this event is supposed to gather more than 300,000 participants. The current record 20,000.

Even though, Mrs Obama acknowledges that the main purpose is to make physical fitness a real priority for parents and kids, she said in a press release:

“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.”
