I have had the privilege and pleasure of training with Helmut for some time. He is a very experienced martial arts and martial arts instructor. Helmut has been actively practicing martial arts since his youth and has a very wide range of expertise. He conveys it very well and responds to the students individually. His self-defense course is effective and deliberately simple in structure, so it can also be implemented realistically. I can recommend his course to everyone because of his human and personable nature, every unit is fun, I can always take something important with me. My mindset has improved tremendously through the training.
