As a part of her ongoing campaign against childhood obesity, the first lady Michelle Obama announced Monday that the Guinness world record for most people doing jumping jacks in a 24-hour period was broken Oct. 11-12.
Obama, along with over 300,265 people partnered with National Geographic Kids to do jumping jacks around the world.
The old record was just over 20,000 people
"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," Obama said in a video released by the White House.
"This is a remarkable achievement, but we know that this isn't only about one day in October," she said. "It's not just about jumping jacks or even a world record. We've got an even bigger goal to go after: ending childhood obesity in a generation so that all our kids will grow up healthy and strong."
