Nandor Albertus

I was a small, skinny and weak child, and grew up to be a tall, skinny and weak adult. To change that I started to train martial arts as a hobby in 1994, when I was 17. I got hooked straight away. I realised that my body was neglected and I have to improve everything.


I trained grappling, striking, weapon-based styles, weight training and cardio. In 2008 I became an instructor and started to teach part-time. I've been working as a full-time Personal Trainer since 2013. That year I discovered hard style kettlebell training and passed the prestigious StrongFirst SFG1 certification in 2014. Since then StrongFirst principles (Google it!) are the core of my training. 


The main focus of my training sessions is building strength and pain-free mobility - that seems to sort out the body composition goals as well. My client’s results are there to prove it.
