On October 11 at precisely 3 pm, First Lady Michelle Obama kicked off the National Geographic Kids challenge to break the world record for the most people doing jumping jacks in a 24 hour period. Accompanied by local school children, the First Lady took to the South Lawn and led the children in an exercise that does everything the experts say we need to do to keep our kids healthy and fit. And best of all - the kids didn't need equipment, just enthusiasm!

Something exciting is happening today on the South Lawn of the White House. In partnership with National Geographic Kids Magazine, First Lady Michelle Obama will launch a challenge to help break the Guinness World Records® title for the most people doing jumping jacks in a 24-hour period.

Today, First Lady Michelle Obama was joined by a big group of helpers for the third annual White House kitchen garden fall harvest. Students from Bancroft and Tubman Elementary Schools got their hands dirty picking produce from the garden and then had a chance to try some of the vegetables that they picked on grilled garden pizza. 

Since First Lady Michelle Obama’s announcement of Let’s Move! Child Care (LMCC) on June 8, 2011, nearly 1,300 participants have registered online and joined the fight against childhood obesity. Among the participants are child care providers who have committed to achieving best practice recommendations for the five LMCC goals—physical activity, screen time, food, beverage, and infant feeding—and trainers dedicated to providing technical assistance to child care providers participating in LMCC.
