First lady Michelle Obama says her "Let's Move" physical fitness campaign isn't about telling the American people what to do.
Obama tells ABC's "Good Morning America" that improving diet and exercise habits is "a national security issue."
The "Let's Move" campaign will be a year old next month, and President Barack Obama's wife has recently been taking it to military installations. She says in the interview broadcast Friday that too many young military men and women are "unable to train" because of weight, fitness and nutrition programs.
Mrs. Obama says her physical fitness campaign "has never been about the government telling people what do to." Instead, she said the emphasis is on giving people information about nutrition and fitness so they can make better choices for themselves and their children.
