Re: Jiu Jitsu Demo
Well DB, if you are motivated, very fit and have good aptitude then the quickest you can get to a black belt is 3 years. That is except rather than the norm. Otherwise you are probably looking at between 5-10 years. However it does not end at black belt, after the black belt there are the dan grades.
Green is an intermediate belt, at this grade and above you should be fairly proficient in the art. If you took it up tomorrow then I think within 3 years you should be fairly good in it and have a good grasp of the art.
Initially when people start they tend to rely more on brute force and when they become experienced they start using techniques more and start using their brains more. It is a good cardio and also does develop your body and muscles as you practice grappling and throwing opponents.
