Martial arts.
From Kreuzberg.
With Love.

Come by and train with us in the heart of Berlin. A fantastic community with experienced coaches awaits you. Together, we bring out the best in you.

Our Classes

On over 1500 m², we offer you a broad spectrum of martial arts, fitness, and recovery. You decide for yourself whether it's Mixed Martial Arts, Muay Thai, Brazilian Jiu-Jitsu, boxing, or wrestling – at Fenriz Gym, you'll find everything a martial artist could wish for. Whether it's for a first trial training or as an ambitious competitor, we have the right course for you. For your active recovery, you can also attend our yoga classes or book a relaxing massage.

Trial Training

You want to try out a free training session with us? No problem! Just come by during our regular opening hours and talk to our team at the desk.

There, we'll advise you, find a suitable date together, and give you a tour of the gym.

Please note that due to high demand, we can rarely offer same-day appointments. For additional useful information about your trial training, please visit our Helpcenter.


We founded the gym in 2010 and have been based at Moritzplatz ever since. Originally starting as a pure MMA gym, over time, we have evolved into a hub for various martial arts with a focus on MMA, BJJ, and Muay Thai.

Seven days a week, our team and community ensure a vast array of activities through over 140 classes. Our fitness area and spacious mat areas provide opportunities for independent strength and technique training or sparring sessions with friends.
