Marek teaches BJJ and No-Gi/Submission Grappling. "Before I started BJJ, I practiced Krav Maga for eight years. I realized I was good on the ground, which is why I focused more on BJJ."

Marek prefers submission grappling. "The beauty of submission grappling is its speed. Besides tactics, explosiveness, conditioning, and improvisation are more important here. That suits my style well."

When Marek teaches, he likes to delve deeply into a technique. "I first teach the basics of a technique and then work through the different options one by one. That way, the technique stays in your system better."

Paul thought it was a good idea to introduce his young daughter to judo. He always watched her lessons, and what he saw was so interesting that he decided to start practicing judo himself. 

​

He eventually found his way to Renzo Gracie Holland for his fitness training. There weren’t many older people practicing judo, but on the mats at RGH he saw more and more people, including many his own age. That made the transition to BJJ very appealing. Since 2014, Paul has been training regularly twice a week. This led to his promotion to blue belt in 2017, and from that moment on he also started teaching children. In 2020, Paul was promoted to purple belt in BJJ, and since then he has been teaching the fundamentals of Brazilian Jiu-Jitsu.

He is currently a brown belt in Brazilian Jiu-Jitsu.
