BTS’ RM Before and After Pics to Show His Workout & Diet Plan is Paying Off

“RM shared on WeVerse that he went for a health check and shared his measurements, of weight gained, muscles percentage, and his body fat. Since BTS “Dynamite” single promotions began, RM’s muscles have been the talk of almost every ARMY these past months. ARMYs have been talking about how buffed he has become that it even got RM’s attention who said that he had been told about it by a friend.

He shared that he has been doing a bit of work out. On his birthday VLive, he had shared that for several years he had not been able to work out because he had injured his shoulder a while back during one of their gym sessions. In September 2020, BTS leader Kim Namjoon, better known to fans as RM, gave ARMY an unexpected yet deeply appreciated glimpse into his personal health journey. Known for his introspective thoughts and poetic lyrics, RM isn’t usually one to boast about physical stats or show off gym progress. But during one casual update on Weverse, he surprised fans by revealing his health check results, complete with details about his weight gain, muscle mass percentage, and body fat levels.

This update sent shockwaves through the fandom, not because of dramatic numbers, but because of what it represented: another chapter in Namjoon’s ongoing story of self-care, discipline, and balance. Let’s take a deep dive into what he shared and why it mattered so much to fans around the world. On September 1, 2020, RM logged into Weverse and casually dropped some health stats with the same ease he might use to share a book recommendation. In the post, he revealed the results of a recent body composition check:

“I’ve gained about 4 kg, and my body fat is down to 15.3%. My muscle mass went up as well. I’m proud.”

Just like that, the message was out, and fans were quick to notice how happy and satisfied he sounded. RM’s tone wasn’t competitive or showy; instead, it was full of self-awareness and personal pride. He had clearly set health goals and was steadily reaching them, and the fact that he chose to share these specific metrics was a reminder that transformation isn’t always about visible abs or dramatic before-and-after photos. Sometimes it’s just numbers on a report—and the feeling of knowing you’re getting stronger.

BTS had an incredibly intense schedule in 2020. Despite the global pandemic, the group released Map of the Soul: 7, performed multiple online concerts, attended award shows virtually, and dropped their record-breaking single “Dynamite.” Behind the scenes, each member also had their own personal routines and pressures.

RM’s decision to focus on his health amid such a busy year spoke volumes. In multiple VLive streams and interviews, he mentioned how the downtime during the pandemic allowed him to recalibrate, not just emotionally, but physically. This Weverse post was part of that reflection. It wasn’t just a health report. It was RM letting fans into his process, quietly sharing that he, too, was working on becoming a better version of himself in ways that went beyond music or artistry.

What made this moment so impactful was how unfiltered it felt. RM didn’t post shirtless selfies or gym mirror photos. Instead, he gave a calm, data-driven update that spoke to his personality: observant, introspective, and goal-oriented. RM’s approach reminded people that health doesn’t have to be flashy. Progress can be measured in quiet numbers, small milestones, and how you feel rather than how you look.

ARMY wasted no time celebrating RM’s progress. Social media platforms lit up with support, with hashtags like #RMHealthUpdate, #ProudOfNamjoon, and #MuscleMonie trending shortly after the post.

Many fans shared their own fitness journeys, inspired by RM’s dedication and humility. Some opened up about working on their mental health, connecting with how RM consistently approaches both mind and body as part of a holistic self-care routine. RM has long championed the message of self-love. Since the Love Yourself era, he’s been open about his struggles with identity, self-worth, and growth. This health update was an extension of that journey.

Taking care of his physical health, building muscle, lowering body fat—these were not vanity projects. They were personal steps in honoring his body, managing stress, and achieving balance. This wasn’t about becoming an action star or fitting a mold. This was about finding a sustainable routine that made him feel strong, centered, and confident. That’s the kind of transformation that resonates deeply, and endures.

RM’s 2020 Weverse update wasn’t a headline-grabber in the traditional sense. There was no dramatic photo shoot or bold declaration. But that’s what made it so powerful. It was quiet strength in action. It was discipline without ego. It was a man sharing his journey not for validation, but to celebrate personal growth. In that one short post, RM gave fans something real to hold on to, a reminder that transformation takes time, and that it’s okay to be proud of the quiet wins. Whether it’s gaining muscle, losing body fat, or simply feeling better in your own skin, progress is progress.

And if RM, the thoughtful, humble leader of the world’s biggest band, can cheer himself on, then so can we.

So now he wants to take it slow and start working out even more. RM has always had a well built body and even muscle during his rookie days. Though he was lean and slender, he still had a good looking well built frame. His bulk up was overwhelmingly received that fans on social media couldn’t stop talking about it. Now that he is working out regularly, we cannot wait to see the final results of his routine.
