SEOUL - South Korean variety shows pushing the human body to its breaking point are dominating screens, and viewers cannot seem to look away.
Netflix’s Physical: Asia
Building on the momentum of the hit franchise Physical
Challenges included some three-hour rope-hangs, endless heavy-pole pushes and hauling massive metal spheres – all of which helped the show become one of Netflix Korea’s standout unscripted entries in 2025.
Riding that wave, tvN is rolling out its own contender with I Am Boxer fronted by Don Lee, the action star behind The Outlaws franchise, and a professional boxing coach.
The series, which is streaming on Disney+, positions itself as a boxing survival competition with a 300 million won (S$265,000) cash prize, champion’s belt and luxury SUV on the line.
Its 90 contestants vary in age and profession, and include actors, athletes, UFC fighters and ex-soldiers.
Producer Lee Won-woong, who previously steered Channel A’s breakout military-survival hit The Iron Squad, said the appeal of I Am Boxer lies in its pure intensity.
“Writer Kang Suk-kyung and I have worked together on many survival programmes since The Iron Squad, but I Am Boxer is, to put it simply, intense. It’s just two people fighting in the ring. We’ve filmed soldiers and done many physically demanding shoots before, but the energy inside the ring was something else. I think that energy will come through the screen,” Mr Lee said during a Nov 19 online press conference.
Mr Kang echoed that view, adding: “The very set-up – the ring, three minutes, two men, going head-to-head – has such a natural rhythm that it gave me confidence we could create a stage that feels almost like watching a live show.”
I Am Boxer, which premiered on Nov 21, debuted at No. 1 across cable and general programming networks in its Friday primetime slot, signalling another potential franchise in the making.
South Korea’s appetite for intense physical competition shows has been building for years.
The Iron Squad has spawned multiple seasons and spin-offs from 2021 to 2024, while Netflix’s Siren: Survive The Island, which pitted teams of female police officers, firefighters and soldiers against one another, became a breakout sensation and won best series at the second Blue Dragon Series Awards.
Pop culture critic Kim Hern-sik says the genre’s staying power taps into something primal.
“Things like strength, speed and endurance are elements humans intuitively understand, so they trigger a kind of instinctive gratification. And the younger the audience, the stronger their focus on that. It’s partly because they feel like it’s something they could try themselves. It feels close to their own lives,” the critic said.
The critic said that fairness is another key factor, adding: “The more we move towards a knowledge-based, artificial intelligence-driven world, the greater the interest in the physical body seems to become. Images and videos can be edited and polished, but the body can’t be faked. I think that’s exactly what excites young people right now – things you can’t achieve overnight.”
According to Mr Lee, physical-driven formats function as streamlined storytelling engines for creators.
“Even these shows that showcase the extremes of physical ability ultimately choose ‘physicality’ as a vehicle to build a story and deliver it effectively to viewers. As storytelling tools, elements like sports, action, strong characters, simple but powerful goals... triumph and exhilaration, and defeat and overcoming are incredibly efficient and compelling,” he told The Korea Herald.
He added that the genre continues to evolve. “Each programme (focusing on testing physical limits) differs slightly in its directing style, structure and expression. I think it would be fun for viewers to notice those differences as they watch.” THE KOREA HERALD/ ASIA NEWS NETWORK
