Michael Weidinger

Head Sensei

I am Michael, a head sensei ofJiu-Jitsu. I began my training many years ago. I was 10-years-old and was bullied a lot at school. My parents thought it would be a good idea if I learnt to defend myself, so I was signed up for a Jiu-Jitsu class. I really liked the training, I learnt to defend myself and have practiced Jiu-Jitsu ever since.

I began practicing jiu-jitsu when I was 10-years-old. At first my parents signed me up for self-defense classes to become more confident and because I was bullied.

The training was tough at first, but I made very dear friends and with time the training became easier. Thanks to my senseis I experienced several moments of sudden realizations and was even more motivated to partecipare weekly.

I never ended up needing to defend myself against the bullies. Instead I gained something much more precious to me. Jiu-jitsu has given me a sense of peace and joy every single week and a strong community. In that way Jiu-jitsu changed my life.

Technique and history consultant

I started my training in 1976, and since then it has only brought me great joy.

During my first lesson, I received a piece of advice, which saved my life in more than one sense.

“No problem is too big to solve and no opponent too strong to be defeated.”


My sensei(teacher) gave me something I could use for the rest of my life. And through patience, hard work and determination I knew, I would find my way. One thing which showed to make a strong difference by learning martial arts was the fact that I learned to read and write, which in so many ways made my life better.


I graduated as a student, got a job and finished a three-and-a-half-year long education in only 24 weeks. Later I became a psychotherapist. My life with Japanese martial arts has for sure improved my personal development. Today I myself am a sensei. A title which could be translated as “the one who has been here before” or “reborn”.


It’s my foremost wish to pass on the same joys, I have experienced in my life, to others.

Also, I would like to thank the senseis I have met during my lifetime. If not for them, I would not have been.
