BTS’ Jungkook has taken over the internet with a gym photo that has sparked a frenzy across social media. On June 11, 2025, following his military discharge alongside fellow member Jimin, an unexpected post from one of his military colleagues became the talk of the fandom. The post featured the BTS maknae shirtless in a gym mirror selfie, showing his muscular build and tattoos.
The accompanying message from the fellow soldier was warm and heartfelt. He thanked the BTS star for making military life enjoyable and supported him moving forward. The gesture instantly went viral. As translated by an X anything, @JungkooksData, the fellow soldiers wrote,
"What's a week? It's been a whole year...Thanks to you, my military life was enjoyable. I'll be applauding you from afar."
The Seven singer had largely stayed private during his military service, so this glimpse into his gym progress surprised many. Fans who remembered his Calvin Klein campaigns joked that he looked even more sculpted now. An X user, @weare_bts7, wrote,
"JUNGKOOK IS CALVIN KLEIN READY!! So cool!!."
Fans shared the images and marvelled at the singer’s transformation.
"BOY WHAT THE HELL IT AINT 24 HOURS YET," an X user wrote.
"I KNOW WHAT’S HIDDEN BEHIND THOSE UNIFORM!!! AAACCKKKK," another person said.
"i can't believe he's that big," a fan commented.
"JUST WHEN WE WERE SAYING HES SO CUTE," a netizen added.
While a few voiced concerns about privacy, most celebrated the warm bond between the idol and his military colleagues and how the tribute reflected respect and friendship.
"he was truly adored by his fellow soldiers," a user remarked.
"Definitely ready to be wowed!," a fan commented.
"You should remove this, JK didn’t share it or as far as we know approve for it to be shared," another one said.
Jimin and Jungkook address the media as BTS' comeback nears
Earlier that morning, Jimin and Jungkook were officially discharged after completing their 18-month service in the Army’s 5th Infantry Division Artillery Brigade. They met the press at Yeoncheon Public Stadium, appearing in uniform and smiling brightly as they saluted the gathered fans and media.
In their remarks, Jungkook thanked everyone who supported them and admitted that it felt strange to be back in front of cameras after so long. He also expressed gratitude to his fellow soldiers and seniors who helped him throughout his service.
Jimin echoed these sentiments, telling fans how grateful he was for their patience during the group’s hiatus and promising that BTS would soon be ready to share new moments with ARMY. He also reflected on the hardships of military life and how strong friendships helped them get through the experience.
The discharge of Jimin and Jungkook comes just a day after RM and V completed their military duties. Now, with only SUGA’s discharge on June 21 remaining, BTS is just days away from reuniting as a full group.
The upcoming BTS FESTA 2025 celebration on June 13–14 at KINTEX is expected to be an emotional moment for both the members and their fans.
