Michelle Obama takes to the South Lawn of the White House Tuesday to break a sweat with a group of local school kids as they join in an attempt to break the Guinness World Record for the most people doing jumping jacks over a 24-hour period.
To break the record, more than 20,000 people from around the world need to get on their feet and do jumping jacks for one minute. The White House event will be reviewed by an official from Guinness.
The recording-setting attempt is sponsored by National Geographic Kids. The "Let's Jump" rules say all jumping jacks must be done during a 24-hour period, starting at 3 p.m. ET Tuesday.FULL STORY
