First lady Michelle Obama led about 400 children in one minute of continuous jumping jacks outside the White House Tuesday.

Other kids around the country also took part, including students at Westbrook School in Mount Prospect. The goal is to break the record for the most people doing jumping jacks in a 24-hour period.

More than 20,000 people must be recorded doing jumping jacks by Wednesday afternoon.
