Kim Jong Kook has never exercised muscles from the beginning. It was in 1998 that the transition of dance practice led to lumbar disc herniation. There is no cure, only by exercising muscles to relieve the pain and the interval of onset, from a dancer in the combination period to a lyric singer in the solo period.

Then, to get to the point, singers also have their own private space. There are many people who love bean fitness in Korea, such as the younger singers who have a good relationship with Kim Jong Kook: Myth, SJ and rain are not all muscle singers. For example, in EXO, Park Chang-ye and Shixun, who took photos with him in the gym these two months, are also exercising their muscles. .

According to Kim Jong Kook himself, no matter how late, he will go to the gym to exercise. I will go after work at two or three in the morning. .

There is no rest day. I go to the gym early in the morning and guide others to exercise in the afternoon. . . .
