Ladies' Home Journal netted itself a big fish for the ever-important September issue: First Lady Michelle Obama, who graces the cover in her own silky blue sleeveless Calvin Klein dress, gently swept-back hair, hoop earrings, and pink lipstick and eye shadow.

Inside the magazine, Obama discusses her new Let's Move initiative, which she spoke to AOL Health about during her first live chat ever last month, aimed at getting kids to eat better and exercise, and opens up about her own routine to stay slim and boost her energy.

Although we don't get any direct tips on how Obama gets those killer biceps, she does admit to waking up at 4:30 every morning to work out and gets through those sessions with a little mental trick.

"I always think, 'Don't think about how you're feeling during the workout. Think about an hour and a half from now, how good you're gonna feel the rest of the day,'" she tells the magazine's editor-in-chief, Sally Lee.

As for encouraging Malia, 12, and Sasha, 9, Obama approaches the exercise issue gently.

Reiterating what she told AOL Health, Michelle explained, "I never talk about weight with my girls. I try not to even talk about my weight. Because you're right, it is a sensitive issue. My girls are preteens and they're seeing their bodies in a whole different way," she says.

"We have conversations around health, food, and activity. I tell them sports are something I want them to engage in because it's good for them. It's good to practice teamwork, to understand what it means to suffer a loss, to win with grace. It has nothing to do with weight, it has everything to do with being a well-rounded person."

When it comes to eating healthy, Obama says she'll indulge in pie and french fries (her favorites) from time to time but otherwise tries to keep a balanced diet and has even employed an all-vegetable cleanse.

"The cleanses are good for a short period of time," she says. "I can't live my life on a cleanse. But they help me clean out my palate. Because when you start adding things like sugars into your diet, you start craving them. And the more you eat, the more you crave... So maybe I'll do a cleanse for two days. It isn't a way of life, because I like food too much. But it is good to break your mind-set."
