It was over quickly.

Sixty seconds after nearly 40 children in the after-school program at the Sanibel Recreation Center started doing jumping jacks, their part of an effort by first lady Michelle Obama’s “Let’s Jump” program aimed at breaking a world record, was over.

The recreation center kids gathered in the gymnasium, and at 2:45 p.m. they started the exercise, after a few warm ups though. At school’s across the nation, children were doing jumping jacks Oct. 12 in the attempt to get more than 20,000 of them in motion for a minute.

At 2 p.m. Oct. 11 on the South Lawn of the White House, Michelle Obama led hundreds of youngsters in their jumping jacks. The national effort spanned 24 hours from Oct. 11-12.

National Geographic for Kids and the White House worked together to put on the event. The Guinness judges will take the final tally and make the determination on whether the world record was broken. According to National Geographic’s web site, this could take several months.

Kids are encouraged to keep jumping on their own because it’s a great way to exercise the whole body. If you do jumping jacks for one minute each day and then add a few minutes each day, you will be able to run faster, jump higher and hike farther.
