Carrie Underwood Stretching In Gym Shorts Shows Off 'The Prettiest Smile'

Carrie Underwood has been mixing her love of fitness with business as she continues to promote her Fit52 workout app. The country singer, 40, made 2020 headlines for jumping into the app space with the launch of her beginner-friendly product, one that's still going strong and often brings Carrie in promo mode on the app's Instagram. In March, Carrie stunned in a hot pink gym look as she stretched her toned body out to plug Fit52, and fans couldn't help but comment on her looks. One user gushed over the "Cry Pretty" hitmaker, noting that she has "the prettiest smile."

Scroll for the video. While a preview snippet showed Carrie stretching from an indoor staircase as she smiled in her Barbiecore tank and shorts, the video quickly switched to a mat setting where the American Idol winner touched her toes while grinning. Flaunting her ultra-toned legs as she went thigh-skimming in her teeny shorts, Carrie showed off her sculpted arms and shoulders, also turning heads with her flexibility as she easily reached her sneaker-clad feet.

Glowing with a lightweight makeup layer and wearing pink cheek blush to match her outfit, Carrie sported her light locks in a ponytail, also flashing her pearly whites. The video, inviting fans to join its Spring Stretch Community Challenge, included trainer and cofounder Eve Overland stretching it out during a yoga session, with a model at the end rolling up her floor mat.

In a caption, Fit52 wrote: "Introducing the fit52 Spring Stretch Challenge! Commit to 52 days of stretching to increase your flexibility, support recovery, and your overall health and fitness. These sessions are designed to fit into your busy schedule and help you build a sustainable habit." Some fans, however, only have eyes for Carrie Underwood. "The prettiest smile on a beautiful woman named Carrie," one adoringly replied.

Carrie's six-pack abs made instant headlines in May 2020, when the star shared this selfie on her Instagram. Smiling from beneath a sunhat as she rocked a leaf-print bikini top and tight bottoms, Carrie dropped jaws with her insanely toned midriff, sending out gym goals galore as she welcomed warmer months.

Grinning from an outdoor terrace, the blonde wrote: "Is it summer yet?" This time, she promoted her CALIA athleisurewear line, founded in 2015.

Carrie Underwood is often touted as having the best legs in the country business, and with photos like these, it isn't rocket science why. On July 15, the superstar singer updated her feed with stage footage while in teeny glitter shorts, marking a show in Chicago and earning over 28,000 likes for the share. Her Fit52 app even offers leg day workouts to get legs just like Carrie's.
