She has trained a number of promising weightlifters, including Ryo Un Hui and Rim Jong Sim who won gold medals at the Asian Weightlifting Championship and the London Olympic Games.

Born in Pyongyang, Kim got interested in weightlifting when she was studying at Korea University of Physical Education. After leaving the university, she became a weightlifting instructor of the then juvenile sports school at the Weightlifting Gymnasium.

Since then, she had studied a lot of weightlifting-related references and data as well as scientific training methods and techniques suited for lifters of different ages.

Thanks to Kim's devoted efforts and ability, her trainee Rim in her teens took the women's 48kg weightlifting title at the Mangyongdae Prize Sports Games held in 2008, startling the domestic weightlifting coaches and players.

Being active as a coach of the Kigwancha Sports Team from 2009, she has worked hard to train competent lifters with unique techniques.
