We need more than 20,000 people to do jumping jacks to break the record. So get your friends, sports teams, afterschool groups--even your entire school--to participate!
Between 3 p.m. ET October 11, 2011, and 3 p.m. ET October 12, 2011, join NATIONAL GEOGRAPHIC KIDS and First Lady Michelle Obama to break the record for the most people doing jumping jacks. All you have to do is one minute of jumping jacks!
Read the rules and find out how you can participate.
(Bonus! Earn a special certificate if your organization helps break the record with a group of more than 100 people!)
