This is Critical Response

Hey, i'm Martin

Since 2020, I have worked intensively with thousands of people from all walks of life, supporting professional groups such as first responders, teachers, caregivers, hospital staff, and security personnel in enhancing their workplace safety. As an independent trainer, I prepare people for violence using my method, Critical Response. Critical Response ist meine Methode.

Years of martial arts training, combined with studies in history and psychology, have given me a comprehensive perspective on violence—not only as a physical phenomenon but also as a psychological, behavioral, and societal issue. The core focus areas for managing dangers—awareness, communication, positioning, combat, and the theoretical background—make the training both effective and realistic.

Critical Response is designed to turn you into a first responder for any dangerous situation. By proactively addressing critical problems, anyone can learn to navigate life with greater strength. Want to learn more about me? Here’s a video.

Hundreds of people have worked with me. Here’s what they say.

Nadine Rybe

“Dealing with violent situations and experiencing them as realistically as possible in training is an important and positive aspect of Martin's training for me. It taught me how to make the most of my opportunities under stress. Thank you! ☺️”

Leon Rosenberg

“I have been training with Martin for 2 years in groups and alone. What I find particularly valuable is the psychological component. Action instead of reaction, switching quickly, consciously deciding to 'act' and seeing it through. These are all skills that you can also use in 'normal' life. And of course, training always pushes you to the limit and beyond, but it's also great fun.”

Thomas Titze

“Very good lecturer with a clear structure!”

Silvi Semmel

“I was able to take part in Martin's self-defense course through the VHS - Krav Maga. It's a good course to get to know yourself and your own abilities and to reassess yourself. This is good for your own self-confidence and self-esteem. In addition to the theoretical introduction, in which it is made clear that the use of violence is only and exclusively for self-protection and danger prevention, there were practical exercises and realistic training. Thank you very much for that!”

Johannes Schild

“I have been training Krav Maga with Martin for many years and his unique selling point is his holistic view of the constitution of self-protection. He combines various perspectives in a profound, theoretically sound and heartfelt way, creating an almost perfect synergy that he implements clearly and didactically in a fun way. The best thing is that he also learns from me and others and has the ambition not to stop learning.”

Christiane Glaser

“I booked the course through the VHS. It was very good! I can only recommend it. I'm already looking forward to more courses. Thank you Martin!”
