uMove x Aikiken Self-Defense Course

Welcome to learn self-defense – in a safe and practical way!

This course, organized by Aikiken ry, is based on a self-defense system called P.D.F.S. (Practical Defensive Fighting System), developed by Kai Koskinen and practiced since 2006.

P.D.F.S. was created to offer high-quality self-defense training for anyone who needs it. The main idea? To help you handle threatening situations – either by getting away safely or taking control – without causing serious harm to yourself or the other person. In real life, these techniques are meant to protect you, which is why we teach both strong (and potentially dangerous) as well as more gentle ways to deal with threats and attacks.

Each course also includes a short lecture on Finnish self-defense laws, so you’ll know what your rights and limits are when it comes to protecting yourself and your property.

By completing the course and the optional level test, you’ll reach the first student level of the system. After that, you’re free to continue training and explore more advanced techniques and practical scenarios. But don’t worry – the level test is completely optional, and you're welcome to join even if you don’t plan on taking it.

No experience? No worries!
You don’t need any background in martial arts to join – just a basic level of fitness to enjoy and recover from the training.

You’re welcome to try the self-defense course during the first week. After that, participation is confirmed by paying the course fee.

On this course the more affordable price is for uMove members.
