Country Star Kane Brown Shows Off Dramatic Fitness Transformation as Taylor Lautner and Other Celebs React

Kane Brown is going “all torque, full speed” into his fitness journey.

The “Miles On It” singer, 31, updated his fans on his ongoing efforts to “come back stronger” in an Instagram post shared on Friday, Aug. 15.

The post featured a side-by-side photo comparison of when he started his transformation and how his body looks now, alongside the brief caption, “From April [to] August and we just getting started! 🔥.”

Brown’s fans and famous friends quickly reacted to the shirtless snaps.

Actor Taylor Lautner, a close friend whom Brown will be starring alongside in the upcoming rom-com The Token Groomsman, jumped into the comments section and wrote, “Dude what are we talkinggg about.”

Brown previously brought Lautner, 33, onstage during his Blessed & Free Tour stop at Staples Center in Los Angeles on Oct. 2, 2021.

Meanwhile, fellow country star Chris Lane replied to Brown’s transformation post with, “That’s insane — teach me your ways buddy 😁.”

Country crooner Bailey Zimmerman also responded, “Inspiring dawg🔥.”

Brown, a father of three and husband to wife Katelyn Jae Brown, has updated fans two other times since he began trying to “get better.”

Most recently, on July 5, Brown explained the fitness journey in a detailed caption, alongside another set of before-and-after photos.

“I’ve never been more motivated,” he wrote. “The real fight is with yourself — every time I want to quit, I keep going. And the next day, I push even harder. If I slip, I hold myself accountable and come back stronger 💪🏽.”

“Let’s get better 🔥,” he continued. “Once you start seeing results, there’s no turning back. You feel better, look younger, sleep deeper, and your mood shifts. Discipline builds everything. Let’s keep going 👊.”

Previously on May 19, in his first fitness update, Brown had encouraged his fans and friends to follow along in the coming months. 

“I’ve been super dedicated to fitness and health,” he wrote at the time. “I would love others to come on this journey with me 💪🏽💯.”

Around that time, Brown gave an update to PEOPLE about his family.

“It’s been cool. I love my two daughters, and so it’s [an] amazing feeling having daughters, but there’s also a different feeling of having a son, and I’m just very grateful that I get to experience both of those,” Brown said, referring to daughters Kingsley and Kodi as well as son Krewe Allen, whom he and his wife welcomed in June 2024. 

The singer added of his son: “And he’s just been so awesome and just so smiley, the happiest baby ever because he’s my boy.”
