Carrie Underwood is in possibly the best shape of her life just months after giving birth.

The 32-year-old country singer did a new photo shoot on Monday for her fitness line Calia, PEOPLE reported. She's currently promoting the Fall line.

The new mom, who gave birth to her son Isaiah on Feb. 27, looks amazing and extremely fit in the exercise gear.

"Having a baby definitely changes your routine," Underwood said while on set. "And I have to work around his schedule. Whenever he goes to sleep, I do the things I need to do for myself and make workouts happen when they can."

Underwood then went on to explain how she loves being able to focus her attention on her family, but she's still been keeping herself busy.

She will be performing all throughout June, and her and husband Mike Fisher will be celebrating their 5th anniversary next month.

"It's been really nice as well to be creative, working on music, working on Calia," she continued. "Making clothing that every woman can wear and enjoy makes me feel good. Definetly one of the most fun parts is all the great clothes I get to wear!"
