Everyone who decides to get into Brazilian Jiu Jitsu must follow the rules and have the proper equipment. This is for the safety of the fighter and of those he or she will be competing against during practice and competition.
But what do you need for Brazilian Jiu Jitsu? For starters, you will need to get yourself a Gi which is the official uniform that is worn by everyone.
The correct uniform has sleeves that are not more than a fist distance up the arm from the waist so that your opponent will be able to grab you which is one way for the opponent to score a point.
Since it is prone to wear and tear, you have to buy a new one every so often. This should also be kept clean at all times and among the different colors around, try getting blue or something darker which for obvious reasons is better than white.
The only way to improve in Brazilian Jiu Jitsu is to spar against your opponent. So you dont inflict any major damage, you should wear gloves and feet protectors.
You can find these online and in your neighborhood sporting goods store. These are available in both open and closed palm designs. This has to be checked by the instructor...
