Chan Sung Jung

When one thinks of MMA fighting and the fighters, we heavily picture a builder person with a muscular body (which is a hulk?).

Anyways, let’s get it real here and not lead to a slightly unreasonable way. And here’s to why is it! Chan Sung Jung is a South Korean professional MMA fighter who is aloof with his small thin, yet strongly packed body.

In fact, he is not the fastest of the guy you see, or strongest or even tallest. Sung Jung is literally not going to put all the eggshells in a basket as he is so well rounded and hard to predict.

Therefore, people have perfectly named him “The Korean Zombie” for his deadly avatar during fights, who would go on like a haunt of the continuous aggressive fight.

The zombie-like fighter has featured in matches as the WEC, Pancrase, World Victory Road, and DEEP. At present, Sung Jung is competing in the Featherweight division for the Ultimate Fighting Championship (UFC).

“I think a lot of people underestimate me as a fighter, so that leads to people wanting to challenge me because maybe they think it will be an easy win. I’m out to prove them wrong. “

Chang Sung Jung | Body Metrics, Workout, and Diet

Sung Jung is a medium-sized man who stands at 5 ft 9.5 in (1.77 m) and weighs 145 lb (66 kg). Similarly, the fighter works out and eats healthily every day. He consumes a lot of protein and nutrient-dense foods.

However, following his devastating loss to Brian Ortega, he gained 20 kgs due to overeating. Furthermore, he believed his career was over, and the loss had a negative impact on his mental health.

Nonetheless, the Korean Zombie got back on his feet and began his healing process by speaking with a psychiatrist. Following that, he resumed his training and appeared to be in good shape in his recent fight against Dan Ige.

He is also a thin, fair-skinned man with short black hair and eyes the same color as his hair. He also has an oval face, chinky eyes, and a wide smile.

Chan Sung Jung | Childhood

Sung Jung was born on March 17, 1987, in Pohang, South Korea, as a Pisces. Not to mention his depressing childhood, which caused him to grow up shy and lonely.

As I take you to his birthday, you should know that his hometown is a port known for steelyards and shipbuilding, and he has no single siblings.

Moving forward, his parents were always working, so he was deprived of their attention. What’s more, he grew up with other people’s families until the age of seven, and because he didn’t get enough quality time with his own, he assumed they (the family he grew up with) were his parents.

His father used to work in the steel industry, mostly lifting stuff out of hot ovens because he wasn’t a particularly strong person. Meanwhile, his mother worked in a clothing store she owns in the city of Daegu, so they were living apart.

While all of this may seem depressing to us, it is quite common in Korea because they prioritize jobs the most. Later, at the age of eight, he returned to live with his family, and he was always that shy, loner kid with no self-confidence, which explains why he never had many friends throughout middle school.

Overall, studying in Nam Yam Ju was difficult. He was from a different region and was introverted, making him an outcast at school, and he was frequently bullied.

Combat Sports (Commencement)

Overall, seeing him in that condition inspired his aunt to enroll him in athletics and martial arts. His aunt forced him into Hapkido classes and gyms when he was fourteen (early adolescence), which he found quite boring at first.

However, as time passed, he grew accustomed to it, honing his social skills and beginning to learn kickboxing, which proved to be a watershed moment in his life, propelling him to where he is now.

Following that, he graduated from Daegu Gyeongbuk Institute of Science and Technology and began training in judo and Brazilian jiu-jitsu.

When he was in his late teens (around the age of 18), he began taekwondo and joined the South Korean Navy. In 2007, he won his first sambo tournament, which was organized by the Korean Sambo Association.

Following that, he won tournaments as the Pancrase Korea Neo-Blood Tournament’s Lightweight division, defeating Yoo In Seok and Lee Hyung Geol.

Following that, in 2008, he made his professional mixed martial arts debut, winning the entire KOREA-8-man FC’s MMA tournament in the 65 kg division. Who would have thought such a shy kid would have to make it through?

Anyway, he continued his streak by appearing in the 2007 Korean television cable show Street Fighter. He won the show in the 70 kg weight category tournament, which was only a stand-up fight and not a ring fight.

Career in Mixed Martial Arts | Chan Sung Jung

As previously stated, Sng Jung made his professional MMA debut in 2007, when he won the Pancrase Korea Lightweight Tournament in December. Following that, he won both of his fights for Japanese promotion DEEP after winning the Korean FC in 2008.

To illustrate, one of his two fights for the DEEP was a unanimous decision victory over Michihiro Omigawa on August 16, 2008. In contrast, his other victory came against Fanjin Son at DEEP: 39 Impact, where he was knocked out in 17 seconds.


Sung Jung made his Sengoku debut in 2009 during the Featherweight Grand-Prix, defeating Shintaro Ishiwatari in the first round at Sengoku 7.

At 4:29 of the first round, he won with a right-hand blow followed by a rear-naked choke submission as Shintaro surrendered.

He advanced to the second round of Sengoku 8 on May 2, 2009, after winning the first round. Unfortunately, he was eliminated in a unanimous decision by eventual winner Masanori Kanehara.

Due to Sengoku’s biased history against Koreans, the game caused much dissatisfaction among fans. Even so, let’s move on to the next game from June 7, 2009, when he faced American Matt Jaggers in a reserve bout for the tournament at Sengoku 9.

At the same time, the winner was supposed to step up as a replacement; however, despite winning the match with a triangle choke submission at 1:25 of the second round, Sung Jung was not given priority.

Extreme Cagefighting Around the World

Sung Jung made his World Extreme Cagefighting debut on April 24, 2010 after signing with them.

At WEC 48, he made his debut against Leonard Garcia (replacing the injured Cub Swanson). However, he was defeated by a split decision, sparking debate about the fight’s judges’ decision.

By the end of the controversy, he had won Fight of the Night and the Wrestling Observer Newsletter had declared it the Fight of the Year.

As a result, he advanced to the next match against George Roop on September 30, 2010, at WEC 51, which also ended in a knockout loss in the second round.

Chan Sung Jung | Fighting Style

Sung Jung is known for his aggressive, violent fighting; hence he was named “The Korean Zombie” for his deadly fights. Unlike other players, who play wild and crazy, Sung Jung is a rare player to keep the fight who expresses themselves with their moves.

All in all, if you search for aggression, deadly matches, he is the one you have been looking for as he knows only to move forward to take the opponent’s soul no matter how his condition is.

Not to leave out, he is a master of Taekwondo, Hapkido, judo, and Brazilian jiu-jitsu. Overall, he has also set the record to win a fight with a twister submission, which is the first-ever in UFC history.

Michael Bisping on the broadcast team had stated, “We call him the Zombie, but don’t get it wrong, he has tremendous technique.

It’s the fact that it’s the technique combined with the desire to finish every fight. Through the years, he’s become very tactical, and he still believes he can be a champion one day.”
