Our training sessions

Training in the Underground Style with old-school iron and a dash of creativity!

Training offerings

An hour of pushing and sweating during a great workout while it feels like only fifteen minutes have passed. That’s the natural high we aim for during our training sessions.

We work together on your strength, endurance, explosiveness, fitness, and determination. You’ll quickly notice that you feel better and more balanced. Of course, with a bit of muscle soreness here and there.


Group classes

Together, yet alone. During our GROUP CLASSES, you have the advantage of motivated people around you who, just like you, want to give their all. However, even in our group classes, you always train at your own level.

After all, it’s about your body and achieving your own goals.

Can be combined with Kickboxing.

Starting from 49.50


Small Group

In our SMALL GROUP sessions, you train with a small group of up to 5 people. This allows us to tailor the training even more to your unique body and personal situation.

We always have your back for the best results.

Starting from 115


personal training

Unwavering attention and endless expertise. During our PERSONAL TRAINING, we work one on one to ensure that you train in a healthy way that suits you.

It’s a great way to stay motivated and finally achieve your New Year’s resolutions. We do everything in our power to make sure you push your limits.

Every single time.



Are you ready to fight? Great! With us, you can learn KICKBOXING from real professionals. The perfect way to improve your fitness, clear your mind, and better handle yourself in everyday life.
