Ju-Jitsu is a fun sport for youngsters from ten years old
and for adults.
In this sports discipline there are a lot of different levels called Kyu or Dan. Oh I've forgotten to say, that everybody has to wear a belt. All levels have another belt with a different belt colour. There are sixteen levels/belts (also in my judo school). At the beginning there are the learner levels. The test for this level happens in the own school.
After the learner levels follow the master levels. These tests are organized by the Swiss Judo & Jiu Jitsu organisation.
I currently have a white-yellow belt so there is a lot to learn for me :o)
