I have trained with Marty and Gav since I started bjj about 5-6 years ago. Both men are very passionate, knowledgeable and open minded on and off the mats. Both are clear and concise when it comes to demonstrations, attending up to date seminars and are always open to helping others who come into their gym. I'll be popping in again soon to get beat up 😀. Anyone who is interested in doing bjj within the Ballymena area, call into Kinetic and give it a go.
