If there’s one thing BTS leader RM has proven, it’s that where there’s a will, there’s most definitely a way. Just weeks before the group’s highly anticipated ARIRANG album drops on March 20, 2026, RM has stunned the entire ARMY — and even his own bandmate Jin — by revealing he has shed a whopping 15 kilograms since his military discharge. The weighing scale moment that broke Weverse? Pure gold.

The Weverse Post That Sent ARMY Into a Frenzy

On February 21, RM hopped onto Weverse with the kind of update that no fan was prepared for. He posted a photo of his weighing scale reading 68.8 kg and captioned it with a Korean phrase that loosely translates to: “It happens when you do it” — essentially, when there’s a will, there’s a way. Simple. Motivating. Quintessentially RM.

Fellow member Jin immediately dropped into the comments with his reaction, writing “Wow, amazing” — and honestly, same. RM then clarified in his replies that he had been 83.8 kg during his time as a sergeant in the military. That’s a 15 kg transformation in roughly eight months post-discharge. Not bad for someone who also somehow announced a San Francisco Museum of Modern Art exhibit in the same month.

The Whole Group Is Getting Back in Shape

RM isn’t the only one putting in the work. V has openly shared how he’s been losing the muscle mass he gained in the army, while Jungkook recently posted a late-night treadmill selfie — making it very clear that BTS means business ahead of their return. The group’s first comeback in over three years and nine months is shaping up to be an all-out event, and every member seems determined to show up at their absolute best.

With South Korea’s mandatory military service system meaning the entire group had to enlist and discharge at different times, getting everyone back on the same physical and creative page has been a genuine journey — and the ARIRANG era is the beautiful result of that.

What’s Next for BTS?

The ARIRANG world tour kicks off April 9, 2026 at Goyang Stadium, spanning 81 stops in 34 cities globally. ARMY, prepare yourselves — this reunion is going to be on another level entirely.
