Carrie Underwood In Gym Shorts Shows Off Stunning Birthday Body

Carrie Underwood put on her best smile as she posed for a sporty photo shared to her Fit52 workout app's Instagram earlier this year. In March, the country singer's 2020-founded brand uploaded a snap of her to mark her 40th birthday, but the promo game was still there as Carrie encouraged users to sign up. Posing in a hot pink workout look as she showed off a healthy glow, Carrie stunned as she flaunted her toned figure in shorts and a tank top, and she even commented on the post. Carrie, who also runs her CALIA athleisurewear line, is now well-established in the celebrity fitness space and even fronts sports drink BODYARMOR.

Scroll for the photo. Leaning against an indoor staircase as she held a water bottle, Carrie sent out major workout vibes as she flashed her world-famous legs in a thigh-skimming pair of gym shorts. Keeping coordinated in her bright pink tank top, the Grammy winner highlighted her rippling biceps and sculpted shoulders, also showing off her flattering smile.

Posing with her hair in a ponytail and plenty of pink cheek blush matching her outfit, Carrie kept glam with glowing highlighter, but her vibe was more post-training glow than heavy stage makeup.

In a celebratory caption, Fit52 shouted out its famous founder, writing: "Sending big love to the one and only @carrieunderwood on her birthday! In honor of the gal with the greatest legs of all time, we invite you to give her famous Leg Workout a try today."

As fans flocked to the comments to wish Carrie a happy birthday, the star herself noted the response. "Thank you @fit52 fam!" she wrote. Carrie Underwood's sports-centric business ventures are packing a punch. CALIA is followed by over 500,000 on Instagram, while Fit52 has now topped 100,000 followers.

Carrie Underwood is reported to have a net worth of $140 million, although the bulk of it is probably from her best-selling music and tours since she won American Idol in 2005. That said, with celebrities these days earning more from their brands, chances are the blonde is enjoying healthy profits from both of her brands.

"Fitness is a true passion for me," Carrie stated as her app launched. She added that it "incorporates what I've been doing myself for years, and we've made it easy and totally accessible for anyone that wants help to work in working out. We worked really hard to create a high-quality, user-friendly app that is designed for busy people and their busy lives."

Fans don't see Carrie Underwood in swimwear too often, but this 2020 photo is still live on her Instagram. Rocking a patterned bikini in black and white, Carrie welcomed summer, adding a "Choose You" hashtag as she shouted out her CALIA brand.
