Carrie Underwood just dropped jaws, proving her rock-hard legs might take over her powerhouse voice. The 37-year-old country superstar and 2005 "American Idol" winner has been busy promoting everything from her "My Gift" Christmas album to her 2015-founded clothing line, with yesterday bringing the latter in a fresh Instagram update. Carrie, who founded her CALIA by Carrie athleisurewear line in 2015, doesn't always appear in the brand's promos. When she does, fans go wild. Check out the killer workout look below.

Scroll for the photo. Carrie, whose killer pins are now legendary, had posted in skintight spandex leggings with a paint-on effect highlighting the toned and gym-honed legs.

The photo showed the "Southbound" singer in the doorway of her home garage and striking a confident pose in her gray and paint-splash leggings – pops of yellow and white matched a t-shirt, with Carrie seen unzipping a black quilted sports jacket.

A caption from the brand mentioned its "Stay The Path" hashtag, reminding fans that the stylish apparel can "take you from workouts to wherever."

Carrie's brand, which retails at Dick's Sporting Goods and online – in fact, it ranked third after Nike and Under Armour at DSG in 2016 – now sees fans telling the singer to just open a physical store.

"It sure would be nice if Dick’s sporting goods would display & sell your items nicely," one fan replied, adding: "It’s like a messed up hodgepodge of your brand at our DSG here in Columbus OH. BETTER YET... open your own Calia store!!!! ❤️"

Carrie is definitely building an empire. In March, the mom of two dropped her diet and exercise book, "Find Your Path," also releasing the Fit52 app, which early users admitted finding addictive. The "Cry Pretty" singer has also been opening up on her own exercise philosophies, including her past mindset, this year shocking fans over a reveal she only ate 800 calories a day after winning "American Idol."

Nowadays, Carrie calls her workouts her "self-care." "This is how I feel good about myself, and this is how I operate," she told Women's Health. More below.

Carrie, whose Fit52 app is based around a deck of cards representing 52 weeks in a year, has admitted she can't always squeeze in the workouts, particularly with 5-year-old son Isaiah and 1-year-old Jacob.

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

Carrie's brand, now boasting a cult following, has, however made negative headlines this year, with fans complaining that prices were too high.
