We all love the Korean variety show Running Man, and we do adore the members' personalities. But now, South Korean artist Haha revealed that all was not happy, all the time behind-the-scenes.

During an interview, the 37-year-old, whose real is Ha Dong-hoon, detailed about the hardships the crew went through during the shoot. He revealed: "My spinal disc problem became so bad that I needed to undergo a procedure. My 7th disc burst seriously. But I couldn't say that I was not well. I thought everyone went through the same thing. It could be that my doctor was exaggerating, but he told me I was almost paralyzed."

Adding on, he dished about the injuries other Running Man members had. He said: "Yoo Jae Suk-hyung's ankle is twisted, and he has problems with his ankle, back, and neck, as well as his fingers. Gary-hyung has problems with his shoulders. He can't hold up a patbingsoo bowl because he tore one of his ligaments."

"For variety show members such as us who use our bodies, it's like we're athletes. But we don't have time to recover. If we get seriously injured, that gets edited out. There are things we just can't talk about, since making others laugh is our priority," he continued.

Previously, South Korean actor and entertainer Lee Kwang Soo had talked about the variety show. During an interview with High Cut, Song Joong Ki's best friend talked about being on the show. He said: "It takes about a day to film every week, but it has become a part of my life. It's the equivalent of waking up in the morning and drinking water. It just feels natural."

Kwang Soo continued: "The show has brought me to where I am now. Seeing the members once a week feels so good."

The show will conclude in February 2017.
