Absolutely brilliant experience. Knud is a legend. Takes you at whatever pace suits, whether that be complete beginner or very experienced. Everything from start to finish was perfect and the amount you learn in 5 days is phenomenal. If you’re interested in Martial Arts and learning something new, just do it, you won’t regret it.

Knud organised and delivered a fantastic training course for our two sons, in challenging corona-circumstances. We were very impressed.

I liked everything. Knud is a very good teacher who made the classes fit my specific needs. I learned a lot in those 5 days and looking very much forward to keep practising. Thank you!

"Great set of tools"
The training provided me with a very effective set of tools to get out of "problematic" situations. I learned a lot things that I hope to never need to use to their full extent.
The overall experience was great and put me on another level. Thanks Knud!

"Martial arts that works"
I am from Australia and came to the training with a brown belt in defensive combat (Krav Maga). The training very quickly made me realise how much I still had to learn. I left the training with a new focus and more skills. Mr Knud was one of the best instructors I had the privilege to learn from. He is humble, knowledgeable, do not criticise any other forms of martial arts, builds your confidence, explains the risks and benefits of every move he teaches and certainly the real deal when it comes to practical experience. A must training for anybody that wants to excel in defensive combat. I can’t wait to go back every year for a refresher. But most importantly, I believed that I made a martial arts friend in Mr Knud. Thank you for an excellent week.

"Kluge und wirkungsvolle Selbstverteidigung"
Die ruhige und kompetente Art des Unterrichts, die Erfahrungstiefe des Lehrers, die wunderschönen Orte auf Feld und am Elbstrand und nicht zuletzt das feine Essen.

"Dad plus two kids from The Netherlands"
We (56, 21 and 19 year old) wanted a special holyday together and had a wonderful, safe and relaxed stay at Knud's and his great wife Karin's place. Except of my son, my daughter and I had no martial experiences and all the three of us learned Knud's very effective self-defense method very easily. We had fun, had an excellent and patient teacher and (still) felt very "strong" after the training. If you want to experience something special, gain more confidence, or like to feel more secure and safe: don't hesitate any longer and book a week with Knud!

"Middle aged princess ninja? Well, maybe"
I'm a 50+ woman who travels solo lots, whether in Australia or elsewhere. I had zero self defense skills (apart from running away in a hurry) and wanted to remedy this. Knud is brilliant: Easy- going, patient, a skilled trainer and communicator, and did I say patient? Like the techniques Knut uses, his training method is both efficient and effective. (For me, that's the sign of a good trainer.) If Knud can get me doing these moves, he can train anyone. I loved this stuff... and I'm keen to keep at it. Just shows, it's never too late to start MMA!

"Great experience. Highly recommended!"
I arrived from New Zealand the morning that the training started - and really didn't have to worry about anything once I got to the station in Itzehoe. I had a fantastic week - Knud just made everything work. We ended up training at the beach most days. As a complete beginner, I found his explanations clear, the teaching well-structured, and progress really satisfying. I highly recommend to others!

"Perfect place to relax and learn "
Knud is a nice guy. He explained clearly the details of the movements he taught. He is patient and modest in teaching and sharing his views.
The training place is quiet and cosy in the green nature. A nice mind refreshing experience.

"Exceptional Trainer & Amazing Host "
I would like to start my review by thanking BookMartial Arts for this great experience, I have used their services in connecting me with two Camps so far. One in China Rizahoe and this is the second one in Itzahoe Germany. Both experiences were exceptional and very well organized. Knud, my trainer in Germany is an amazing trainer with huge excellent experience in fighting and mainly in teaching. I went there with Zero experience, I left feeling like a LION. If you are a beginner, he's your man, he took his time explaining to me each move and how to use it. If you are professional and looking for a REAL SERIOUS training, he's your man as well. He was generous, caring about little details and funny, which made the class more interesting. the training place was in a quiet area, where you can really cleanse your lungs from the city pollution. Clean and on point. I wish I can upload all the pictures and training videos ...
