The Community of people who love jiu-jitsu
Our story
Jiu-Jitsu Collective is a Brazilian jiu-jitsu academy based in Oslo, built around consistent training, technical depth, and a strong team culture.
The academy was founded with the idea that progress in jiu-jitsu happens best in a supportive, focused setting. We value good training habits, attention to detail, and a culture where people can train with intent.

Classes are structured, the atmosphere is welcoming, and the standard on the mats is kept high. We train jiu-jitsu in both gi and no-gi.
Our community includes people from different backgrounds who share a common interest in jiu-jitsu. Beginners are supported from day one, while more experienced students are challenged to keep refining their game.

Jiu-jitsu is an individual pursuit trained collectively. Progress happens through focused training with others.
