SEVENTEEN’s Woozi Shows Noticeable Physical Transformation During Military Service
SEVENTEEN’s Woozi has surprised fans with his dramatic physical transformation after spending nearly a year serving in the military.
The idol enlisted as an active-duty soldier on September 15, 2025, and is currently completing his mandatory service in the Republic of Korea Army.
Since beginning his service, the SEVENTEEN member has remained largely out of the public eye, with fans receiving only occasional updates through official channels.
A new photo of the idol with his fellow soldiers recently went viral online, with many fans focusing on how different he looks compared to his pre-enlistment days.

Korean netizens also joined the conversation, commenting on a familiar trend among male idols who appear to gain muscle during their military service.
It’s so funny how idols go to the military and come back as guys in their 30s who love bulking up lol. They must have wanted to do it so badly.
