BTS is officially back—not only in the recording studio but also in the gym. As the world’s biggest K-pop group gears up for their highly anticipated Spring 2026 comeback, the members have been undergoing rigorous physical training while working on new music in Los Angeles. With long hours in the studio by day and grueling workouts by night, BTS is rebuilding itself both musically and physically.
Inside BTS’s Training Routine
Celebrity fitness trainer Ma Sun-ho, known for working with Korea’s top athletes and entertainers, flew to LA to personally oversee BTS’s program. In a behind-the-scenes vlog on his YouTube channel, Ma gave fans a rare glimpse into the group’s transformation, ensuring their return is not just a musical event but also a visual upgrade.
The routine is relentless. Ma begins his day with a 6 a.m. jog, followed by BTS’s morning weight-training sessions before they head to the studio. Some members even return for a second workout in the evening, underscoring their commitment. The vlog showed the members pushing through heavy lifts, staying laser-focused, and grinding through tough sets with impressive stamina.

Experts Weigh In
What sets BTS apart is their use of “training to failure”—an advanced, high-intensity technique where exercises continue until the muscles are completely fatigued, sometimes with assisted reps beyond that point. According to celebrity trainer Kirk Myers of LA’s Dogpound Gym, this method builds muscle quickly and effectively.
Another highlight of BTS’s regimen is precision. Instead of rushing through reps, they focus on slow, controlled movements, maximizing muscle engagement and reducing injury risks. Myers noted that while swinging weights may look impressive, true strength comes from resisting momentum.
Even with their dedication, BTS is not immune to setbacks. Jungkook, famously disciplined with his workouts, was encouraged to rest due to shoulder soreness. Trainer Ma reminded fans that rest and recovery are essential parts of progress—not signs of weakness.
Teamwork in the Gym and Studio
Despite the intensity, BTS keeps their trademark camaraderie alive. Playful moments—like V teasing Jungkook about faking an injury—show that their bond remains strong, whether on stage, in the studio, or at the gym.
The group has been based in LA since July, balancing recording sessions with training, all in preparation for their monumental comeback. With new music and a revitalized image on the horizon, fans can expect a whole new version of BTS in 2026.
