First Lady Michelle Obama is embarking on one of her biggest challenges yet. Mrs. Obama, along with hundreds of local children, will attempt to break the Guinness World Record for the most people doing jumping jacks in a 24-hour period.
Between 3 p.m. ET October 11, 2011 and 3 p.m. ET October 12, 2011, jumping around will be going on and all you have to do is one minute of jumping jacks!
More than 20,000 people need to participate in order for the record to be broken, so get your friends, sports teams and after school groups to participate!
We actually think this will be an easy task for the First Lady, she is always running and jumping for a good cause. Take a look at some of her most athletic moments in our accompanying gallery!
