Way to go jumpers! With your help, National Geographic Kids has broken the Guinness World Record for the most people doing jumping jacks in a 24-hour period! Between 3 p.m. on October 11 and 3 p.m. on October 12, 300,265 jumpers all over the world took part in the event–far surpassing the existing record of 20,425!

Breaking the record is a huge accomplishment. But the First Lady and her organization, Let’s Move, still have a lot of work to do to meet an even bigger goal: ending childhood obesity within a generation so that all children have a chance to grow up healthy and strong. To reach that goal, Let’s Move is working to make sure all kids get the nutrition they need, have a chance to be active each day, and receive support from their schools, families and communities.
