Mixed martial artist Choo Sung-hoon, appearing on SBS Plus’s ‘A Man’s Guide to Traveling in Kyushu,’ revealed a grueling training regimen that suggested a return to active competition.

On the afternoon of the 28th, during an episode of the SBS Plus variety show, Choo visited a gym in Kyushu, Japan, with singer Kim Jong-kook and Big Bang member Daesung and immersed himself in a circuit workout. After finishing the nonstop, high-intensity session, he was breathing hard and drew everyone’s attention.

From the sidelines, Daesung clicked his tongue and said, “There’s another beast here — a wild animal.” He joked, “With guys like this around, others can’t work out — they’re too scared,” prompting laughter across the set. Kim Jong-kook, widely regarded as one of the entertainment industry’s most committed fitness enthusiasts, repeatedly expressed amazement at Choo’s intense movements.

Kim asked Choo, “You’re not retired yet, are you?” Choo replied, “No, I haven’t. That’s why I’m doing this,” signaling he still has the drive of an active competitor.

Kim praised him, noting, “What’s impressive is that no one has to tell him to push — he keeps going until his breathing picks up. He does it on his own, even at this age.”

Choo remained modest despite the praise. “All athletes train like this,” he said. “There’s nothing special about me.” His strict self-discipline — pushing himself to his limits as if unconcerned with age — left a strong impression on viewers.
