These two actors have a lot of savagery in their punches.

Amateur boxing was a way for these two performers to get their start in acting.

Ahn Bo Hyun

At the national level, Ahn Bo Hyun represented Busan and earned a gold medal in the boxing tournament. When Ahn Bo Hyun was in middle school, he began boxing. He worked hard as a boxer for six years, despite the opposition of his parents.

Although Ahn Bo Hyun had a promising amateur boxing career, his parents' criticism and worry about his future led him to abandon his ambitions to pursue a professional boxing career.

In the end, Ahn Bo Hyun made his debut as a model with a model-worthy height of 188cm. Acting began for him formally in 2014, and he has been in several films, including "Golden Cross", "The Dearest Lady", "Descendants of the Sun", and "Her Private Life".

In "Itaewon Class", Ahn Bo Hyun took a giant step forward in his acting career. Since then, the popularity of "My Name" and "Military Prosecutor Doberman" has made him a household name among actors in their 30s.

Ahn Bo Hyun, a former boxer, has proven time and time again that he excels in action movies. Ahn Bo Hyun's boxing career, on the other hand, has left him with a scar.

When he appeared as a guest on "Amazing Saturday," he revealed, "I got hit a lot while training. That explains why I'm having hearing problems right now."

Lee Si Young 

As a boxer, not an actress, Lee Si Young gained her fame by competing in the national women's rookie amateur boxing competition and Seoul's amateur boxing competition, both of which she had previously competed in.

Despite being cast in a drama, the actress decided not to participate since she was focusing on her boxing career, as she stated in an interview.

Incheon City Hall, an amateur boxing business team, recruited Lee Si Young in 2013 and he went on to win the national championship that year.

Even though Lee Si Young is no longer competing in boxing, her strong resume in the sport led to a big break in the acting world.

When she first started acting, Lee Si Young was mostly seen in romantic comedies, but she's already carved out a niche for herself in non-stunt action roles.

Lee Kyung Gyu's star-making influence goes beyond Kang Ho Dong, as Hong Jin Kyung shares how he helped her kickstart her career.

On the April 24 episode of KBS 2TV’s Problem Child in House, legendary comedian Lee Kyung Gyu appeared as a guest—and a touching story from the past was revealed.

Hong Jin Kyung surprised everyone when she said, “He’s the teacher for all of us. Personally, he’s the one who helped me debut.” She even pinned a carnation flower on his chest to show her gratitude.

Lee Kyung Gyu smiled and said, “I still remember when Hong Jin Kyung walked up the stairs onto the stage for the first time.”

Hong Jin Kyung then shared her journey to becoming a star. “I joined a supermodel contest, but only the top 3 winners were noticed in broadcasting. I got a special prize, so I had no chance to be on TV."

She continued, "At first, I was just a backup for a show. But somehow, I became a regular the next week. I never knew why."

She added, "I thought the PD gave me a shot. But then one day, I randomly met Kyung Gyu sunbae, and he told me it was actually him who recommended me.”

Kim Sook asked with a smile, “So Kyung Gyu sunbae said nice things about you to the PD?”

Lee Kyung Gyu playfully replied, “Don’t say it in such a childish way,” making everyone laugh.

He then explained more seriously, “The show was Scoop TV Entertainment, and I was pretty much the main MC. When Jin Kyung showed up, I saw her determination and passion."

He added, "While others didn’t seem serious, she really stood out. I told the PD, ‘She seems unique. Why not keep her on the show?’”

Kim Jong Kook chimed in, “So if the main MC said that, doesn’t that mean you basically got her in?”

That made Lee Kyung Gyu happy. He grinned and replied, “Exactly! You speak well. Be like him!”

He added, “After that, Jin Kyung’s career took off. She started doing shows with Lee Young Ja and just kept going.”

Fans are now calling Lee Kyung Gyu not only a top MC, but also a quiet star-maker behind the scenes!
