In July, I had the special privilege of joining the First Lady as a member of the President’s official delegation to the opening ceremonies of the Olympics. Before attending the opening ceremonies, we gathered on the lawn of the residence of the U.S. Ambassador to Great Britain for a Let's Move! event to get kids exercising. Thousands of children were there, including the children of our military members stationed in the area, participating in dozens of sports. Mrs. Obama is definitely hands-on when she joins kids in exercise and games. She is a non-stop advocate for healthy activity and good, clean, competitive fun. And, she is a powerful role model for healthy living and the pursuit of fitness for Americans of all ages.

Ed note: Last week, First Lady Michelle Obama was the guest editor for the iVillage website. She worked with the editors there to create a weeklong series of great articles and videos with advice for families looking to Rev Up their Back to School Routine and introduce healthy new habits for everyone in the household. The editors of iVillage asked readers to share their own strategies for making changes stick in their families. Before you can cook for your family, you need to know how to grocery shop for foods you’ll use. From how to make a list to making healthy choices, consider this your go–to cheat sheet.

To help American families become more active and meet the First Lady’s fitness goals, Let’s Move!, and Partnership for a Healthier America (PHA) have teamed with USA BMX to provide easy access to the healthy sport of BMX.  This collaborative initiative will provide a 30 day membership to BMX for new riders across the country who sign up on PHA’s website. Once registered, the participant will receive a 30-day free trial membership to their local BMX track.

Everyone is talking about the great event First Lady Michelle Obama held at the White House Monday for the winners of the Healthy Lunchtime Challenge. Mrs. Obama  invited the 54 young chefs whose original recipes for healthy, affordable and delicious lunch menus were selected by a panel of judges to join her in the East Room for a luncheon celebration. We invite families to try a few (or all!) of the great recipes that were created for this contest at home yourselves.

Sydney created these Baked Zucchini Fries to accompany her Homerun Meatloaf Burger. “I thought I could show kids how delicious vegetables could be when you think of fun and creative ways to add them to your meal,” she says. She likes to serve this with fresh strawberry lemonade. —Sydney Brown, age 11, North Carolina

First Lady Michelle Obama sent the message below to the White House email list, to let people know about first-ever White House Kids' State Dinner -- you can watch it live online later this morning: Hello -- Tomorrow is going to be a special day at the White House, and I wanted to make sure you got a chance to be a part of it. At lunchtime, 54 kids from all over the United States will join me in the East Room for the first-ever Kids' State Dinner.
