Marek teaches BJJ and No-Gi / Submission Grappling. “Before I started with BJJ, I practiced Krav Maga for 8 years. I noticed I was strong on the ground, which led me to focus more on BJJ.”

​

Marek prefers Submission Grappling. “The beauty of Submission Grappling is its speed. In addition to tactics, explosiveness, conditioning, and improvisation are more important. That suits my style well.”

​

When teaching, Marek enjoys diving deep into a technique. “I first teach the basics of a technique and then go through the various options one by one. That way, a technique stays better in your system.”

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.

Theo is the team leader of our youth programs and teaches the Brazilian Jiu-Jitsu Juniors classes with great passion and enthusiasm. He started training in BJJ himself because his son was practicing judo. Now, they’re often seen together on the mat working to improve their BJJ skills.
