Carrie Underwood already has her pre-baby body back -- and she's showing off her hard work in a new shoot for her fitness line!
Looking slim and toned just four months after welcoming son Isaiah, the singer modeled outfits from her CALIA by Carrie Underwood collection, which can be found exclusively at Dick's Sporting Goods and on the line's website.
"Fitness to me—I've been vocal about it over the years—is a lifestyle. I just love how I feel when I feel good about myself. There's definitely a lot of me in the Calia line," the new mom told E!.
With a newborn baby at home and her NHL playing husband, Mike Fisher, busy with hockey, the "American Idol" winner admitted that "workouts may or may not happen."
"It's been interesting getting back into my fitness routine ever since I had Isaiah," she revealed. "It's the most wonderful thing in the entire world but of course there's so much that comes along with having a baby—your schedule completely changes," she said. "I have to kind of be ready to workout whenever I possibly can."
