Ewoud van Dulken

Born in Amsterdam and raised in Amstelveen. After swimming, gymnastics, soccer and diving I came into contact with the sport of judo. I started judo at the age of 10 and became a black belt judo in just under 6 years.
Tijdens mijn eigen judolessen ben ik gaan assisteren om zo de mede leerlingen en mijn leraar te kunnen helpen met de lesstof. Het was echt iets voor mij! Dit heeft mij doen besluiten om mij te gaan specialiseren als sportleraar op het CIOS te Haarlem. Tijdens deze zeer brede opleiding ben ik 2e en 3e dan (zwarte band) geworden en daarnaast heb ik ook mijn ‘lesgeefbevoegdheden’ (Judoleraar A en B) gehaald.
Tijdens mijn opleiding ben ik in vele landen geweest waaronder Japan, Zuid-Afrika, Frankrijk, Duitsland, Tsjechië, België, Polen, Denemarken, Noorwegen, Finland en Zweden. Ik ben bevoorrecht dat ik hier kon proeven van de judocultuur en de wedstrijdsport.

Jay van Andel

By now, 15 years of experience as a judoka with teacher Ewoud van Dulken.
I started practising judo at an early age; I was five years old. We did this in the local gymnasium where we also had our PE lessons with school.

Judo was my first experience with sports besides swimming. At the age of eight, I started playing tennis besides judo. In this, I was driven by the wins. It soon turned out that I bit into winning every match I played. In both judo matches and tennis competitions, I often won prizes. To make it to the top, I had to make a choice, judo or tennis. I chose tennis at the high level and not without success.

Meanwhile, the sport of judo kept gnawing at me, I would sometimes just go and watch the class or join in once in a while. I just couldn't let it go.

While studying at CIOS, I had the opportunity to do an internship at the judo school. It totally got my enthusiasme back again which led to weekly training and teaching my own classes.

Quitting judo I can't, it's just my nature.

Jonathan Gal

I am Jonathan Gal, born October 12, 1975 in Amsterdam and raised in Amstelveen. As a little boy of 4 years old I was already on the mat. Judo has always been a red thread for me. During my youth I competed at a high level. I trained with Karel Gietelink, Kenamju and sometimes traveled to France, Italy and Japan for various training camps. Later in life I participated in team competitions in which Ewoud was also part of. We trained a lot together and won many matches together. Currently I practice the game twice a week as a sport, outlet and to stay fit.

Besides my work, I am still regularly on the mat, not only as a judoka but also as a trainer. I like to help driven judokas push their limits. Just training hard is not enough, mastering technique is another branch of sport. By mastering a technique completely you can always use it, at any time. My favorite throw? Tai- Otoshi.

In the upcoming period, I will be providing competition training at the judo school. Here we will go deeper into the favorite competition techniques of each judoka. Together we will go deeper into the technique, dissect it and polish it where necessary. Then we will add combinations and variations to create a wide range of techniques around the favorite throw.

As a father of three boys, I did not have to hesitate for long which sport to choose for them. I knew better than anyone else that judo contributes to a good and healthy foundation. It offers so much more than just the sport!

Motivation of Master Ewoud

Judo is a sport for everyone, even if you don't have that much to spend. Don't have any martial arts experience? Are you afraid of falling Judo is for boys and girls from 3 years old. Also for (starting) adults. Our motivation is to get as many Amstelveners as possible in touch with themselves and the unique sport, judo.
It starts the moment you put on your judo suit, tie your belt and step onto the mat. Learn to fall and rely on yourself. Build self-confidence and resilience. Judo school Amstelveen offers judo as a sport, but it is more than a sport. It is a life lesson. During structural judo lessons at one of the elementary school in Amstelveen, children learn social skills, respect for each other, discipline, cooperation and perseverance at an early age.

Judo, Physiotherapy,
personal training & Fitness

During my studies, I took "fitness" as an additional specialization. Here I specialized in physiology, training theory and writing training schedules. After my internships at major gyms and agencies, I also focused on 'personal training'. Not with an eye on bodybuilding, but on sport-specific training and rehabilitation training. From 2007 to 2021, I worked in physical therapy and began to specialize on NAH (Non Congenital Brain Injury). The results and progression of the clients made the work fun. It made me realize that every improvement offers an improved quality of life. That's what makes the work so valuable. Striving for more, striving for perfection. Achieving perfection is often impossible, yet striving for better or striving for the best achievable is certainly possible. I have experienced it myself through many hours of training and throwing myself wholeheartedly into the things I do. In 2018 I earned the title "personal trainer of the year" and I prolonged this title both in 2019, 2020, 2021 and 2022.

Strong, Persevering, Balanced, Patient and Fanatical!
