Ronin Do Fight Gym

Ronin Do Fight Gym is a martial arts club in Sundbyberg offering training in JuJutsu, Karate and Kickboxning for all ages and levels. The club was founded in 2005 and runs 22 classes per week, with the option to combine one or more of the disciplines. Competitive branches include Kyokushin Karate (Knockdown), Kickboxning, Kempo and Allstyle – though the majority of training focuses on technique and personal development rather than competition.

The atmosphere is described as friendly yet serious, and the club is led by 17 instructors. Founder Mats Tverin, titled Hanshi, has over 40 years of experience and has been inducted into several international Martial Arts Hall of Fame organisations. Instructors at the club have represented Sweden at national, European and world championships, including a national gold medal in Kyokushin Karate in 2021.

Well suited to those who want to learn self-defence or martial arts from scratch, as well as those seeking high-level competitive training. Children's training is also available, with separate classes tailored to age and level.
