If first lady Michelle Obama has her way, she’ll be etched in Guinness World Record book history by 3 p.m. this afternoon, thanks to her “Let’s Move” campaign.
At the time of this writing, Mrs. Obama was currently entrenched in an attempt to shatter the Guinness World Record for the most number of people doing jumping jacks in a 24-hour timeframe.
In order to succeed, Mrs. Obama will need more than 20,425 people around the world to do one minute of jumping jacks, starting at 3 p.m. EDT yesterday and ending at 3 p.m. EDT today.
To help her, she recruited around 400 local students from D.C., Maryland, and Virginia for an event at the White House Tuesday afternoon. As you can see, Mrs. Obama led the students in their one-minute jumping jack obligation.
“I’m the first lady and I get to do a lot of things, but this is really exciting,” Mrs. Obama said before the jumping began. “I never thought I would break a world record.”
National Geographic Kids magazine helped set up events around the U.S. for students who couldn’t make it to the White House but still wanted to participate.
Take Roosevelt Middle School in San Francisco. More than 750 students will be jumping today with teachers and even the school’s principal, according to the Bay City News Service.
Highland Park Elementary (Minn.) students got their jumping jacks in at 2 p.m. yesterday, according to the Associated Press.
The folks at Guinness will be reviewing all the nationwide events to determine if Mrs. Obama exceeded the 20,425-person threshold. Once Guinness releases the official word, you’ll hear about it here.
