Jaehun Park is South Korea’s most successful Classic Physique bodybuilder — a five-time Mr. Olympia competitor whose legs have earned him the nickname “Jaehoon Platz” back home. 🇰🇷
He is the first Asian athlete ever to win the Classic Physique title at the Texas Pro, the first Korean to break into the Olympia Classic top 10, and the winner of four IFBB Pro League shows.
And he is still going. In 2026 he placed 3rd at the New York Pro, 4th at the Pittsburgh Pro and 14th at his fifth straight Mr. Olympia. This is his updated biography.

🎓 From ROTC Officer to the Youngest Korean Pro
Park was born in Seoul on 24 February 1995. He studied social physical education at Dongguk University’s Gyeongju campus and completed South Korea’s mandatory military service as an Army officer, discharged as a lieutenant.
He started competing as a student — he was already winning college and provincial bodybuilding shows in 2014–2015 — and swept first places and overall titles in his first season after leaving the military.
In 2019, at just 24 years old, he earned his IFBB Pro card. Korean coverage notes he was, at that moment, the youngest Korean ever to turn professional. 💪
His Pro League debut came at the 2021 Asia Grand Prix Pro, where he placed 4th — a quiet start for a man about to make a lot of noise.
🥇 2022: The Monsterzym Breakthrough
Almost nobody outside Korea knew Park’s name before June 24, 2022. That day, at the Monsterzym Pro in South Korea, he won the Classic Physique title outright — beating fellow Korean Seonghun Park into second place.
The win took him straight to the 2022 Mr. Olympia in Las Vegas, where he placed 15th in a record field of around 70 Classic Physique athletes — beating several established pro-show winners on his Olympia debut.
🏆 2023: A Unanimous Texas Win and an Olympia Top 10
On August 18, 2023, Park did something no Asian athlete had ever done: he won the Classic Physique title at the Texas Pro, one of the strongest shows in North America.
He beat former champion Robert Timms and crowd favourite Logan Franklin — and the published scorecards later showed every judge had him in first place. A unanimous win, on American soil, for a Korean athlete in his first Texas appearance. 🔥
That November he reached his career peak at the Mr. Olympia in Orlando, placing 10th — the first Korean ever to finish in the Classic Physique Olympia top 10. By his own account, he had been in the mix for an even higher placing at prejudging before nerves and shaky posing cost him spots.
He finished the year on December 3 by winning the Taiwan Pro, closing a season-long diet that had run from April to December without his conditioning ever slipping.
🎯 2024–2025: Holding His Place Among the Elite
Park placed 12th at the 2024 Mr. Olympia — a deeper field than ever — then went home and won the World of Monsterzym Open Pro on November 3, 2024, edging Juseong Seo in a close battle for his fourth pro title.
In 2025 he made only one stage appearance — but it was the one that matters. At the 2025 Mr. Olympia he placed 15th in a 59-man field, in the show won by Ramon Rocha Queiroz, where Spain’s Josema Muñoz finished 4th.
Korean analysts noted his arms and shoulders — long his weak point next to his famous legs — had clearly improved, even as the division around him kept getting stronger.
🔥 2026: Podiums in America and a Fifth Straight Olympia
Park opened his 2026 season in the United States, and he came for points. On May 9 he placed 3rd at the New York Pro, behind only Niall Darwen and Diego Galindo.
A week later he added 4th at the Pittsburgh Pro. The two results banked 20 Olympia qualification points — enough to secure his place at the 2026 Mr. Olympia through the points standings.
In Las Vegas on September 26, 2026, he placed 14th — his fifth straight Mr. Olympia appearance, in a top 15 that included the likes of Wesley Vissers. Five Olympias in five years: no other Korean Classic Physique athlete has a streak like it. ✅
Off stage, 2026 was a landmark year too. In January he opened All Right Gym in Suwon — a facility of more than 800 pyeong (roughly 28,000 square feet) that has become a pilgrimage site for Korean lifters — and he has announced his wedding to his longtime girlfriend for November 29, 2026.
🦵 The Legs: “Jaehoon Platz” and the All Right Spirit
Park’s calling card is his lower body. His quads and glutes are so developed that Korean fans nicknamed him “Jaehoon Platz”, after leg legend Tom Platz, and Korean coverage rates his leg development among the best in the entire division.
His training, documented on his popular YouTube channel, is built on heavy weights and high repetitions — in one widely shared session he squats 220 kg (485 lb) for 23 reps. His motto, and his brand, is “All Right”: everything is going to be all right if the work gets done.
Honesty note: detailed day-by-day training splits, exact calorie counts and meal plans for Park circulate on biography websites, but he has not published an official diet plan in English-language media — so this page does not present one as fact. What is verifiable is the training footage and the results it produced.
🔀 Not To Be Confused: The Three Korean Parks
Korean Classic Physique has produced three elite pros with similar names, and databases mix them up constantly.
Jaehun Park (박재훈) is this article’s subject: five Olympias, four pro wins, the Texas Pro champion.
Seonghun Park (박성훈) won the 2024 China DMS Pro and debuted at the 2025 Olympia — read his story in our Seonghun Park biography. He finished second to Jaehun at the 2022 Monsterzym Pro and fourth behind him at the 2023 Taiwan Pro.
And Jaewan Park is a third, separate Korean Classic pro — he actually placed one spot ahead of Jaehun (3rd to 4th) at the 2021 Asia Grand Prix. Three Parks, three different careers.

The Texas Pro trophy, the first Korean top 10, the legs they call “Platz” — none of it was given to him. All right? All right. 🇰🇷
