I can only speak for Carlsons,but i am happy to describe the neccesary attributes required to gain a Blue Belt at our club.
Firstly-The rules are-There are NO rules,because everyone is different.Everyone has a different fighting style,different bodies and different brains,reflexes and attitudes.We encourage people to use their
attributes to their advantage.
If you are strong,it's natural to use your strength.
If you are clever,it's natural to use your brain.
If you are patient,it's natural to use your patience.
If you are explosive,it's natural to use your explosiveness
The first thing we are looking for when awarding a Blue is whether the White Belt can submit Blue Belt's of a similar size/weight to himself.
The next thing is,does the white belt get regularly submitted by other white belts,or has that stopped happening.
Does the white belt have a general understanding of posture,base and leverage.
Does the white belt have an understanding of how to escape from unfavourable positions using balance and leverage rather than just strength.
If an 'average' Judo black belt turned up at the gym,could the white belt
avoid getting submitted by him.
If an 'average' wrestler turned up at the gym,could the white belt avoid getting submitted by him.
These are just some of the criteria we will be looking at when deciding
whether a fighter is ready,but EVERY FIGHTER IS DIFFERENT and there is no SET criteria,everyone is judged on their own merit.
If a white belt wants to force the issue and make it impossible for his instructors to ignore him,a good way to get an early Blue Belt is by winning a couple of competitions in the white belt division.
I fully expect questions like 'What if all the other blue belts in the gym have been blue for 2 years-how will a white belt tap them' and, 'what if a guy is really skinny compared to the gym blue belts so cant tap them but is very technical' and, 'what if he can't tap the blues but hangs with them' and,
'what if the white belt is just a steroid abusing animal who just guillotines everyone and doesn't use good technique'??
Well these questions are why there are NO SOLID RULES and the decision is down to the instructor-because he has the experience to weigh up all the facts and decide if the fighter is good enough to represent his team as a Blue Belt or not.
Fastest Blue at Carlsons-4 months-candidate- Sambo Black Belt who was 85 kilo's of pure muscle.
Average time to get blue-18 MONTHS
Some guys are still white after 4 years.
How long did it take me? 1 YEAR,training 4 times a week with a background in Judo as a kid,kickboxing as an adult and weight training from 15 years old
Hope this helps.
P.S. There are no gradings,no money changes hands-when a white belt is ready he is handed a Blue Belt.Simple.
