A video of Jungkook working out at the gym, showing off his toned muscles and muscular body, is going viral on social media, attracting a huge number of views and receiving countless compliments from BTS fans worldwide.

A 10-second video of Jungkook working out with V and RM has gone viral among BTS fans. The youngest member is almost shirtless, showing off his toned muscles while lifting weights, while V and RM cheer him on. The clip has gone viral on X, attracting a large number of views and many compliments on Jungkook's hard work.

Previously, Jung Kook was often associated with a cute, approachable image. However, after his military service, both he and the BTS members have had obvious changes in body shape and demeanor. Jung Kook's recent appearances, especially when showing off his toned body, have made fans "crazy" because of his maturity and drastic change in style.

On June 11, Jung Kook and Jimin were officially discharged from the 5th Infantry Division in Yeoncheon, Gyeonggi Province, South Korea. The two members completed 18 months of service in the Artillery Brigade of this Division, where they underwent many challenges in both physical training and combat missions. The military experience not only helped the members train physically but also brought about mental maturity, which was highly appreciated by fans.

Suga was the last BTS member to complete his military service on June 21. With all 7 members discharged in June 2025, fans are eagerly awaiting the group's reunion. HYBE announced that BTS is expected to return to group activities later this year or early 2026, promising special music projects and events.

The return of Jung Kook and the members of BTS is not only an opportunity for the group to recreate their hit songs, but also an opportunity for fans to witness the remarkable growth of each member. Jung Kook, who is known as the "golden maknae" of BTS, now has a much more mature figure and demeanor. The new workout video shows that he is not only diligent but also extremely serious about maintaining his fitness, an important factor in helping BTS get ready to return to the stage.

Fans also expressed their delight at how Jungkook practiced with the other members. V and RM not only cheered but also created a fun atmosphere, making the video more intimate and lively. These moments not only attracted international fans but also helped BTS maintain their appeal after a period of absence due to military service.

The completion of military service by all 7 members means that BTS has passed a challenging period on an individual level, preparing for strong group activities. Fans expect the group to soon release new music products, hold grand concerts and reaffirm their position in the K-pop market.

Looking back on the past journey, from the first days of enlistment to his return, Jung Kook's change is not only in his appearance but also in his confident and professional demeanor. The images of him training hard and trying to overcome the challenges of military service have increased the admiration of fans for BTS's youngest member.

The growth of Jung Kook and the members is a testament to teamwork, discipline and passion for music – factors that have helped BTS maintain their position as the world's top group.
