What’s BJJ and its different weight classes?

brazilian jiu jitsu

Here is a thing about Brazilian Jiu-Jitsu (BJJ). It is a contact sport where you can bring down the opponents twice your size with ease if you have enough skills and technique. BJJ teaches you a lot about discipline and dedication to learning the art. It’s not just about self-defense, but it also tells you how to take down your opponent.

However, the first thing that you will have to deal with will be weight classes and age divisions. The weight classes here are very different if you compare them with other contact sports. For the newcomers, there is GI and No GI. And then there are master and adult categories for men. Separate categories are in place for women as well as juveniles.

Things can get pretty tricky here. You are so confused about choosing your category that you even forget in which category you are allowed to compete in. So weight class eligibility is a must, and this post is going to help you with that.

GI or No GI

Before you start weighing yourself, you need to understand that there are two different types of BJJ competitions in which you can participate. One is GI, and the other is No GI. In a BJJ GI competition, you will be fighting in the uniform.

You will wear this uniform when you weigh-in, and you will only get a single shot at it. If you don’t make it to your weight class that you are straight away disqualified, and there are no second chances or refunds. And of course, you cannot change your division either.

The other category is No GI, which doesn’t require you to wear any uniform for the weigh-in. But besides that, every other rule is applicable here.

Choosing the Weight Class – Frequently Asked Questions

How much does a Brazilian Jiu-Jitsu uniform weigh?

Of course, the weight classes are separated by including GI (uniform) or not. Therefore the question that comes to mind is what the weight of this BJJ GI is. The answer is something that you must know if you are serious about competing in IBJJF competitions.

Most of these BJJ uniforms weigh around 4 to 5 pounds. The best uniforms in terms of quality and everything else will weigh around 4 pounds. It is because they are built for training as well as competition.

Which competition should I prefer: GI or No GI?

If you are a fresher than you need to train in both the competitions, you shouldn’t limit yourself to one type of competition. It is important that you gain as much experience in this sport as possible. But if you are looking to go for the top IBJJF competitions, then it is better for you to train with your GI. And the reason is that the top guys in this sport only prefer to compete in their uniform.

Should I reduce weight to get into a lower category?

Most of the beginners and some top professionals come across this question. Will reducing weight allow you to beat your opponents and prevail in that category! Well, the simple answer to this question is yes, it will. Lighter weight categories are less challenging, and there is nothing ambiguous about it.

But you must think about the fact that when reducing weight, would you be able to maintain your stamina and strength? Losing weight might weaken you, and you might end up not being able to compete. The matter is to cut enough weight to dominate the lower weight class. But don’t cut too much weight, or you will be sidelined due to your physical condition.

What food or drink should I go for before my bout?

Make sure that you go for clean food and you can use water as well as other sports drinks in this regard. Don’t drink anything caffeinated or too sugary. Focus on complex carbs because they are slow to digest, and they can provide you with long-lasting energy.

So you can nibble on these throughout the day but don’t over-eat them. Simple carbs can break down quickly, and they are good for quick energy bursts. Fats and proteins are great for long-lasting energy.

When taking supplements, only focus on the ones that your body likes. Don’t over an experiment on the day of your bout and time you supplement consumption. If you think that you’re going to be on the mat in the next 20 minutes and consume your supplement. But in reality, your turn comes in after an hour, then that support it’ll consume that energy in you.


If you are serious about competing in Brazilian Jiu-Jitsu tournaments, then there are some precursors you have to deal with. One is GI, and the other is No GI. GI BJJ competitions have uniforms while No GI BJJ bouts don’t involve any uniforms.

But if you are looking to reach new heights in this combat sport, then you need to choose GI and train in these competitions.

Some people come across an idea to reduce their weight and dominate the lighter weight category, and you can do so the one you’re skilled enough in your art.

Heavier weight categories are more challenging, and cutting your weight for domination is a smart move. But don’t overdo it, or you will be disqualified from competing in your category.
