How have you started doing fitness?
I grew up with sports. But more important is my will to live a long and healthy life by being in my best physical and mental state possible. My search of that led me into the sector.

When was your last further training?
Human Foundations Level 2 of Functional Patterns.

What´s your fitness goal?
Living the most healthy life as long as possible and sharing my knowledge with as many people as possible.

What´s best of being a trainer?
I like helping people to reach their goals. Especially in cases where people suffer from pain needlessly.

Describe yourself in three words.
Dedicated, inquisitive, helpful.

You can come to all regular Krav Maga training sessions at our locations in Hanover, Sarstedt or Brunswick as a Member of Julian Kramar Krav Maga. Our offer contains Beginners, Advanced or Level Training as well as Women and Children Courses.


This is where you train certain topics intensively in four hours. Like that there is enough time to get into the topic and to inherent it afterwards. No matter if you are a beginner or on an advanced level – there is something for everybody. A membership is not necessary.


Wether you are looking for a staff outing, a hen or a bachelor party or a children´s birthday party – Julian Kramar Krav Maga offers the option to bring any event in an unusual setting. Ask us and we develop an individual Krav Maga package for you and your needs.

Personal Training

You do have a tight schedule and you wish for an individual support, where you can train result based and goalorientated after your visions? Personal Training is the right thing for you then – only you and Julian Kramar Krav Maga. Whenever and wherever.

Why Krav Maga?

If you are threatened or attacked, you will have to defend yourself – no matter the situation: Going for a run in the park, after doing shopping in the underground garage, as a passenger in the subway or directly in front of your door. With Krav Maga you can defend yourself effectively. Arrange your trial session NOW and get to know the techniques!
