Marcin Reszka is one of the most sought after self-defence experts in the country. He has been a leading Krav Maga instructor in the UK for the past 14 years


Marcin Reszka – Self-defence expert

His self-defence journey started in Poland as a boy when he came across some martial arts books and decided to begin training in “tae-kwon-do” before switching to kickboxing and boxing through his teenage years. He had one aim, to take as much experience from each discipline as possible in regards to their application for self-defence.

He then joined the infantry mountain division in the Polish Army for three years including a one year operational tour as a member of the NATO peacekeeping force in Kosovo.

Marcin moved to the UK in his early twenties and studied Krav Maga full time eventually becoming an instructor and achieved expert level distinction while attending training camps in Israel.

He continues to study other disciplines for his self-defence knowledge and among others he is currently a brown belt under the legendary Roger Gracie in Brazilian jujitsu.

He also qualified as a knife fighting instructor and specialises in defending against knife threats and attacks.

Marcin gained valuable real life experience from years of working on the doors of London bars and nightclubs. He studied the psychology of violence and aggression and how to diffuse tense situations before they spiral out of control.

This long journey has greatly influenced Marcin’s view on self- defence, combat, fitness and life in general.

During the last few years while training students at his club, working with select private clients and running seminars for security personnel on the close protection circuit he has developed his own unique approach to self-defence.

His passion is to pass on his knowledge and empower people to be able to carry themselves with confidence, avoid threatening situations and to defend themselves if needed.

He has created the Urban Self Defence programme to deliver this vision combining effective self-defence instruction alongside functional fitness workouts
