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.
