Carrie Underwood Sticks To These Foods — And Red Wine! — To Maintain Her Killer Legs & Strong Arms

Country crooner Carrie Underwood is as well known for her hit tunes as she is her killer legs and arms — and she hasn't taken any shortcuts to get there.

With two kids and a booming career, it can be hard for the star to find time for herself, but she's learned to make that a priority, explaining, "My self-care is my gym time, and that's a stress reliever for me."

"If I can work out seven days a week — which doesn't happen, but if I can — I'm going to," she explained. "Because the next week, I might get two days."

Of course, the star also sticks to a healthy diet, but she's admitted in the past that she went overboard when it came to staying in shape, which is what spurred her to start using MyFitnessPal, which helps her track her diet that's 45 percent carbs, 30 percent fat and 25 percent protein.

Nowadays, the singer eats a tofu or egg-white scramble along with Ezekiel toast and some berries (accompanied by a cup of coffee), for breakfast. She'll munch on a sandwich made with "vegetarian meat and avocado" for lunch, and for dinner, will whip up a veggie-packed dish like a stir-fry.

"I'm always roasting vegetables, making sweet potatoes, veggie burgers or spaghetti squash," she revealed. A protein bar or a green smoothie are her go-to snacks.

Underwood, who released her athleisure line Calia in 2015, also indulges in a small piece of dark chocolate or a glass of red wine, the latter of which she names as her "vice."

Once she learned what worked for her own body, she decided to help others find their a suitable routine by releasing her book, Find Your Path: Honor Your Body, Fuel Your Soul, And Get Strong With Fit52 Life.

"I want to be healthy and fit 52 weeks of the year, but that doesn't mean I have to be perfect every day," she shared. "This philosophy is a year-round, common-sense approach to health and fitness that involves doing your best most of the time."

When it comes to staying on track, readers can get some extra help by downloading the Food52 app, which offers workouts of various levels. Underwood also admires the app since it gives her structure.

"I love rules," she confessed to Women's Health. "This is how I feel good about myself, and this is how I operate."
