Full attention for your child? We do not understand the question.

Our instructors see every child. The hand that needs adjusting. The kid who suddenly pulls back. And they take care of it – in that same class.

For parents

Does this sound familiar?

  • My child is shy and holds back in groups.

  • My child gets rattled or teased easily.

  • My child has a hard time focusing.

  • My child is often wild, restless or quick to get frustrated.

  • I want my child to learn to say a clear "no".

  • My child needs more movement, structure and good role models.

That is exactly why KAMPFKUNST HERZ® (Martial Arts Heart) exists – for kids learning to trust themselves.

Our approach

Some kids only watch during their first class. A few weeks later they proudly show off everything they have learned at home. On their own. In the living room. Over and over!

At KAMPFKUNST HERZ® it is about more than techniques, kicks and tornado spins.

Kids in a martial arts class
01

Courage. In kid size.

A kid who demonstrates a technique in front of twenty others raises their hand differently in class on Monday.

02

Focus that carries into the classroom.

Kids who learn to finish a sequence calmly in class take that to the desk at school. Teachers are often the first to notice.

03

Learn to fall. Learn to get back up.

Your child lands on the mat, gets up, dusts off the uniform and lines up again. By the third time, without checking whether anyone was watching.

Starting school

The world gets bigger. So does your child.

New school. New rules. New faces. Here your child lines up with kids they have never met before the first day of school – and knows three of them by name by the end of class.

Trying a new technique, even when it does not work right awaySpeaking up to ask for something to be shown againListening to the end of an instruction, even a long oneStanding tall, even when nobody is watching.Burning off the energy that would otherwise land at the dinner tableShoes off, bow, begin – the same every class
Programs

One class. Exactly the right age.

A three-year-old needs a different tone than an eleven-year-old. That is why your child joins a group where they can keep up. Right for their age, right for kids, right for learning.

“She’s just shy.”

Have you been saying that for years too?

Shyness is not part of a personality. It is a state – and states can change. In class at KAMPFKUNST HERZ® it always happens in small steps: first watching, then joining in, then proudly showing what they can already do. No child gets thrown in at the deep end. Every child gets to grow brave at their own pace.

5 out of 5 stars
Our daughter has been going to this martial arts school for a while now and we could not be happier! She feels completely at home there and looks forward to every class. Tomek from the teaching team is incredibly caring, patient and motivating with the kids. After a short time we already see progress in coordination, confidence and how she gets along with others. A clear recommendation for anyone looking for a professional and warm-hearted martial arts school!

Our story

Wait until you see your child like this.

Kim Marc Herzog knows the path from unsure kid to strong personality from his own experience. As a child with ADHD, dyslexia and little confidence, he found structure, stability and courage through martial arts. Today that story has grown into a life school that makes kids stronger – not just physically, but above all on the inside.

There is a reason it is called KAMPFKUNST HERZ® – Martial Arts Heart. Our instructors teach your child the art. The heart is there from the very first class.
YOUR TRIAL CLASS

So easy your child could book it.

Workout clothes are enough. You stay right there. Your child takes off their shoes, lines them up along the wall and gets picked up at the edge of the mat.

Pick a location

Choose the location closest to you.

Grab a time

An open slot. Booked online. No phone call.

Enjoy the trial class

First watching. Then barefoot on the mat. Then the first kick into the pad. And at some point the moment your child forgets you are watching.

Decide in your own time

The two of you experience the class, talk about it on the way home and decide at your own pace.

FAQ

Questions on your mind. Answers without the runaround.

Nothing. You book online, show up in workout clothes and head home afterwards. No invoice, no follow-up call.
After class we tell you what your child did. You talk about the rest in the car. Try it first. Then decide in your own time.
They can sit next to you the whole first class and just watch. Then barefoot to the edge of the mat. Then one exercise. Watching already counts as being part of it here.
No. The mat has marked spots, a clear start and a clear end. After two classes, wild kids know where to stand, when to run and when to wait.
A bow when stepping onto the mat. Not because someone demands it – because everyone does it. That is how tough it gets here.
Some get the first technique quickly, others need several tries. Both get the same nod.
Yes. You sit on the side and watch. In the first few minutes your child usually turns around a lot. Later, not at all.
Every child develops differently, so we do not name a date. The first moment often happens somewhere else entirely: putting on shoes, when your child says they can do it alone now.
