Car dealer Jo Jin-hyeong is one of the 100 contestants taking part in a brand new Netflix series which has been dubbed a real-life Squid Games.
Competitors on the series have to take part in all kinds of challenges, testing their physical and mental strength. Jo Jin-hyeong went head-to-head with ex firefighter Hong Beom Seok during episode 3.
The Physical 100 star had heads turning when he entered the room during episode 1 due to his strength and size.
Who is Jo Jin-hyeong?
Jo Jin-hyeong had some of the other Physical 100 competitors intimidated when he was first introduced on the show. One contestant, Lee Guk-Young could be heard saying that Jin-hyeong’s forearms were “three times the size” of his.
The Netflix star is 41 years old and explained during episode 3 that he is the winner of The Strongest Man.
Speaking on the show, he said: “Well, overall, I think I’m big. My neck’s 20 inches, my forearms are around 20 inches, too. And my thighs are about 31 inches.”
Jo Jin-hyeong was chosen to fight in episode 3
After Physical 100’s first challenge, the contestants had to take part in one-on-one fights in an arena.
During epiosde 3, Jo Jin-hyeong was chosen by ex firefighter Hong Beom Seok for a match.
He wasn’t expecting to be chosen by Hong Beom Seok but defeated him and remained in the competition.
Jo Jin-hyeong was selected as one of the 10 team leaders in Quest 2 during Physical 100 episode 4.

He writes in his bio that he’s an ambassador for Indian Motorcycle and often shares snaps of himself working out and training in the gym.
In September 2022, Jo Jin-hyeong posted a photo of himself smiling with his fellow Physical 100 co-star Choo Sung-Hoon.
He captioned the post: “Brother Sung Hoon Choo thank you for making today such a pleasant place. To know you are strong and cool brother, it’s so good. And such wonderful little brothers. Celebrity manager lol. It was fun, trainer.”
Jin-hyeong also has Kikwan Seol from Physical 100 commenting on his photos, so it seems that the cast of the show crossed paths before filming.
