I can see most people here no nothing about the "Belt" In any version of martial arts Belts are ALL
decided by the "Dojo" Some use 6-8 different colors and some use "Degrees" Example Yellow belt 2nd degree
all the way up to Black belt 8th degree or some places the 9th Degree Black Belt. Also heres the important part
you may earn a black belt at a certain dojo BUT if you decide to transfer to another the "Sensei" May not accept
the Belt and start you at a lower belt maybe even "White" which is the first belt you get at ANY dojo.
As for time it varies from dojo to dojo, It may take years. It all depends how dedicated you are to the ART.
My Son is only 6 years old and has been taking martial arts for 2 years and is a 1st Degree ORANGE Belt. He
went from White to Yellow to Yellow 2nd Degree to NOW Orange Belt, He will start competing soon.
You do not get into martial arts to learn how to hurt people but to defend yourself and SELF CONTROL meaning
I Know I can kick his ass but why prove it unless he hits me first
If you really want to learn if you can only spare 1 night a week that is fine just concentrate and take it very seriously
you will enjoy the experiance it gets really fun when you start SPARING.
As for moving up in rank after the session you get tested the session may last 12-20 weeks depending on the dojo
if you know your moves and test well you move up.
Most american dojo's teach Karate or Tae Kwon do or a Form of it.
