where it all began!
Defiant Martial Arts, which was previously recognised as RMNU (Robson Moura Nations United), was established in 2013 and has grown from strength to strength with each year that passes. Our students have grown to love the ethos of the Brazilian Jiu-Jitsu mentality and lifestyle that Defiant Martial Arts provides.
We believe that Brazilian Jiu-Jitsu can change lives and can have a positive impact on anyone!
The wide spread of Brazilian Jiu-Jitsu and Mixed Martial Arts was bound to have a direct impact in Northern Ireland and we welcome you to join the ever-growing art.
