“Even I didn’t know I got this big.” Actor Yeo Jin-goo is once again drawing attention for his impressive bulk-up, and fans are shocked by his transformation—especially after he appeared noticeably bigger than the 109kg national athlete-turned-entertainer Kang Ho-dong.
On August 18, 2025, the YouTube channel Workman uploaded a video titled “Yeo Jin-goo, three times bigger than Kang Ho-dong,” which reignited buzz about the actor’s striking physique.
In the video, actor Um Tae-goo casually asked Yeo about his workout routine. Yeo replied, “I mainly do weight training these days. If it takes long, I go for about three hours. Otherwise, it’s usually two hours.”
He added, “Since I was young, I’ve had a body that gains muscle easily. But even I didn’t realize how big I’d gotten. I don’t check the mirror much while working out, but when I stood next to Ho-dong hyung during promotions for The Great Escape, I thought, ‘Wow, I’ve really grown.’ I figured I need to balance out my proportions a bit,”* he laughed.
Back in July, Yeo went viral after appearing next to Kang Ho-dong in a still from the TVING original variety show The Great Escape: The Story. The image quickly spread online, surprising fans with Yeo’s bulked-up frame that rivaled, if not surpassed, that of the famously strong Kang Ho-dong.
More recently, on September 12, Yeo was spotted in Tokyo, Japan, sporting a softer, fuller appearance that continued to stir curiosity among fans. Some netizens remarked he had gone beyond simple bulk-up and entered “fluffy” territory.
Despite the chatter, Yeo remains down-to-earth and humorous about the attention. His transformation is not just about image—but a result of dedicated effort and a natural build that responds well to training. Yeo Jin-goo starred in The Great Escape: The Story, which aired on TVING this July.
