The Pop Shop and Collingwood invites jumping jackers – both young and old – to help them and National Geographic Kids Magazine set the Guinness World Records® title for the most people doing jumping jacks in a 24-hour period. To break the record, more than 20,000 people worldwide need to complete one minute of jumping jacks in events occurring between 3 p.m. ET October 11, 2011 and 3 p.m. ET October 12, 2011.

The jumping will be held in front of The Pop Shop (729 Haddon Ave) on Tuesday, October 11 at 4:30 p.m. and again on Wednesday, October 12 at 11 a.m. when Collingswood’s Mayor Jim Maley and Commissioners Joan Leonard and Mike Hall will lead the jumpers. Everyone is invited to jump – the only requirement is that participants jump for 60 seconds.

“Let’s Jump!” supports First Lady Michelle Obama’s Let’s Move! campaign, which encourages kids and families to get healthy and active. Mrs. Obama is scheduled to kick off the 24-hour period with one minute of jumping jacks at the White House.

National Geographic Kids magazine encourages kids and families to get teams, classmates, organizations and communities to join them in breaking the magazine’s fifth Guinness World Record. People can also take a pledge to jump and help break the record at www.teamupandpledge.com as part of Team Up for a Healthy America, Jamba Juice's national grassroots campaign to help raise awareness about the nation's obesity epidemic.
