The most complete fighting system




Fenriz was founded in 2010 as a gym focused on mixed martial arts training. Over the last 10 years it has developed itself into a hub for all things martial arts. MMA and the disciplines that form a part thereof are offered almost every day of the week. The disciplines include BJJ, Muay Thai, Boxing and Wrestling.


Mixed martial arts or MMA for short started in the 80s and 90s when martial artists where trying to prove to each other which martial arts style is the best. The result was the realisation that no single style could beat every other style. Instead, you need the ability to fight standing up, you need to be able to throw an opponent and not be thrown and ultimately you need to know how to fight on the ground. Therefore, martial artists started to train and combine different styles. MMA was born.

MMA Training for beginners

Suitable for people with no prior MMA experience. MMA beginner classes focus on base techniques like simple punches, kicks or throws.


Because MMA covers many different positions and distances our classes are divided into stand-up, takedown and ground classes.

InterMediate MMA Courses

Suitable for people with at least six months of experience in MMA.


The classes include more difficult techniques and chain together basic techniques to effective combinations. The pace is faster and play sparring is sometimes part of this class.

Advanced MMA Courses

Suitable for people with a minimum of one year experience.

The class is 60 or 90 minutes long. Fast paced warm-ups and drills combined with complex techniques and combinations. Paired with sparring sessions our fighters prepare for their fights with these classes.
