In October, Michelle Obama sought to break a fairly obscure world record: "number of people doing jumping jacks in a 24-hour period." With the help of 300,264 friends, she achieved her goal, she announced in a video posted today at Let's Move, handily breaking the old record of some 20,000. More than 400 students jumped alongside the first lady on the White House lawn on Oct. 11, the Christian Science Monitor reports.
Mission accomplished—for now. "We know that this isn't only about one day in October," noted Obama. "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." (Read more Michelle Obama stories.)
