10 out of 10 (1 reviews)

RKC senior, PCC, FMS2

Haarlem, Alphen ad Rijn, Vlaardingen, Aalsmeer
The Netherlands
My name is Martijn Bos and I’m teaching mostly in The Netherlands were I work at Trainingscentrum Helena. This is the place to be for Kettlebell and Bodyweight training, Trojan Workout and Krav Maga.


Aside from my job as CEO of Trainingscentrum Helena and as host for Dragon Door events in The Netherlands, Im an expert level Krav Maga instructor and part of the Expert instructors team. I'm teaching Krav Maga all over the world.

With Physical training I first try to empower my students, physical and mental.

I’ve developed Trojan Workout. A trainings method safety is paramount, strength is the base and a group- or private lesson Trojan Workout gives a full body workout in no more that 30 minutes. Trojan Workout creates a solid foundation for sports and heath in general and Krav Maga in specific. 

You don’t need to be trained before attending a lesson. There is always a skilled instructor attending, that helps you to train the best way for your results! For physical and mental empowerment and strength.

10/10 A cardiovascular stimulus using the Kettlebell
By Ronald Post / Velserbroek, Netherlands

The Kettlebell is widely used during the Trojan Workout of Martijn Bos. This Trojan Workout which is invented by Martijn Bos himself creates a cardiovascular stimulant in the body, with the result that the cardiovascular system also improves during the strength training.

Martijn is a highly skilled and concerned (Krav Maga, MMA, RKC) instructor, who is always looking for innovation and improvement in training so that the wel-being of the members of Trainingscentrum Helena is guaranteed.
