Jens Agger

Ju-jitsu forms the long-standing foundation of his career. Jens began practicing the discipline in 1958. He also trained in several other martial arts, including judo and Shotokan karate. His club biography also mentions Daito-ryu Aiki-jujutsu at the main school in Tokyo, as well as Kon-jutsu and Pentjak Silat.

In 1978, he helped establish his own association. Gentofte Selvforsvars Klub grew out of a group of experienced black belts. Jens is listed as its founder and serves as the club's chairman. The association developed instruction for children, young people, and adults.

The club's history extends beyond regular mat training. As early as 1977, before its formal establishment, the group provided a self-defense course for women. Later, they held training sessions at schools, as well as courses, lectures, and demonstrations for companies and associations. These activities connect the club's work with a broader interest in personal safety.

1958: Starts with ju-jitsu.

1978: Is the foundation of Gentofte Selvforsvars Klub.

The association from 1978 is a tangible part of his contribution. At GSK, technical training and the development of new instructors are linked. Its own training pathway gradually guides students from support tasks to responsibility in teaching.

Integrated self-defence gives the club's work a broader perspective. In addition to physical techniques, the association focuses on preventing and managing confrontations. Jens' role in the founding and day-to-day management connects his personal career with this development of the club.
