Heiko Hahn is studying martial arts and self defense from different styles and systems since about 30 years. He started at the age of 5 with traditional styles, but as he was getting older, his interests transferred to the more "reality based" systems. On his journey through the different arts, he became an instructor for Jeet Kune Do Concepts and Filipino Martial Arts under Paul Vunak. After that experience, he continued his research in the field of the RBSD and met a lot of interesting people and teachers out there, and had the chance to learn a lot from them. The one who had the most influence on his actual training is Richard Grannon. Heiko Hahn is an instructor in Grannon's Beta-8 Combative Syllabus. A lot of the Beta-8 Syllabus is integrated in Heiko Hahn's own training methods. Heiko's focus lies in the question "What will work in a real fight?". He is constantly looking for techniques, concepts and tactics under the aspects of effectiveness, functionality, applicability and learnability. He is also constantly looking for the synergy effects between the different arts and training methods.
