🏆 Who Is Yoon Sung Lee?
Yoon Sung Lee represents South Korea in the IFBB Pro League’s Men’s Physique division, where he is known for wide shoulders, a narrow waist and some of the thickest arms in the class.
Korean sources report that he started training in 2012 and only began competing in 2019 — and that he earned his pro card after just a couple of amateur outings.
The exact show where he won that card is not documented in primary sources, so this page does not name one. What the official record does show is a pro already finishing runner-up in Korean pro shows by the spring of 2022.
🥈 2022: Runner-Up Twice in His First Recorded Pro Season
Lee’s earliest verified pro results came in 2022, when he finished second twice on home soil in South Korea.
At the AGP Pro in Seoul on March 20, 2022, he was runner-up to Bong Seok Choi, ahead of Seungho Chae in third.
He repeated the result on October 20, 2022, at the Korea Men’s Physique Pro, where Junho Lee took the title and Lee placed second in a 13-man field.
Two silver medals in his first recorded season marked him out as the Korean most likely to break through — and the breakthrough arrived the following summer.
🔥 2023: First Pro Win and an Olympia Debut
Lee opened 2023 with third place at the AGP Pro in Gyeonggi on June 17, behind winner Joseph Lee and Gantulga Altankhuyag.
Two weeks later, on July 2, he won the District of Taiwan Pro in Kaohsiung — his first professional victory — beating Wang Hsiang and Minsu Kim, and with it earned his first Olympia qualification. 💪
He made his Olympia debut in Orlando in November 2023, finishing tied for 16th in a field of more than forty athletes won by Ryan Terry.
He closed the year on November 26 with second place at the Japan Pro in Tokyo, behind Jo Uezato and ahead of Juxian He.
⭐ 2024: The AGP Title and a Career-Best Olympia Placing
Lee’s biggest season began on April 28, 2024, when he won the AGP Pro in Gyeonggi with a perfect score in a prejudging-only final, ahead of Jinbo Li.
The win qualified him for the Olympia for the second straight year — and this time he used it in full.
At the 2024 Mr. Olympia in Las Vegas he placed 13th, breaking into the top 15 for the first time. Korean coverage notes it as the best Olympia placing by a South Korean Men’s Physique athlete. 🏅
He stayed busy after Las Vegas: second place at the World of Monsterzym Open Pro on November 3, behind Juxian He — on the same stage where Jaehun Park won the Classic Physique title.
Then, on December 20, he won the Taiwan Pro finale in Kaohsiung, beating Farouq Ishimoto into second place and booking his 2025 Olympia spot early.
🌏 2025: A Third Straight Olympia and a Fourth Pro Title
Lee’s 2025 season centred on the autumn. He competed at his third straight Mr. Olympia in Las Vegas on October 10, finishing tied for 16th in the field led by Ryan Terry and Ali Bilal.
Later that month he placed sixth at the Musclecontest Philippines Pro on October 25.
In November he took third at the Japan Pro, and on December 7 he closed the year with his fourth pro win — the Asian Championships Pro in Kaohsiung, where he beat Anik Ghosh with a perfect score of 3.
That December victory carried an early prize: qualification for the 2026 Mr. Olympia.
