Brazilian Jiu-Jitsu (BJJ) is a grappling martial art focused on ground fighting, control, and submissions. It emphasises technique and leverage so a smaller person can control a larger one without relying on size or strength.
Brazilian Jiu-Jitsu is a grappling martial art built around ground fighting, positional control, and submissions. Rather than striking, you use leverage, body position, and timing to take a person to the floor, control them there, and finish with a joint lock or a choke. The central idea is that a smaller, weaker person can defend against and even dominate a larger opponent by applying technique correctly.
If you have only ever asked "what is jiu jitsu?" in passing, the short answer is that it is the art of controlling another human being on the ground. You aim to climb a ladder of dominant positions, neutralise your opponent's ability to escape or counter, and then apply a submission that forces them to tap. Because there is no striking, BJJ can be trained at near full intensity with a partner safely, which is one of the reasons it has spread worldwide and become the grappling foundation of modern mixed martial arts.
BJJ is practised both as a self-defence system and as a competitive sport. At the elite level it is governed internationally by the International Brazilian Jiu-Jitsu Federation (IBJJF), which standardises the rules, the weight classes, and the belt requirements that most academies around the world follow.

The story of Brazilian Jiu-Jitsu begins in Japan. Traditional Japanese jiu-jitsu was a battlefield grappling art, and in the late nineteenth century Jigoro Kano refined and systematised many of its principles to create judo. Judo placed a strong emphasis on throws and on the ground techniques known as ne-waza, and Kano's students became some of the most skilled grapplers of their era.
One of those students was Mitsuyo Maeda, an accomplished judoka who travelled the world demonstrating and competing in the early 1900s. Maeda eventually settled in Brazil, where he taught the art to members of the Gracie family. Carlos Gracie learned from Maeda, and Carlos and his brother Hélio Gracie went on to adapt the techniques over the following decades. Hélio in particular is often credited with refining the emphasis on leverage and positioning so that a physically smaller person could prevail, partly out of necessity given his own slighter build.
From the Gracie family the art spread across Brazil and then internationally, gaining global attention in the 1990s when Royce Gracie used it to defeat much larger opponents in the early Ultimate Fighting Championship events. That period proved the effectiveness of ground fighting to a worldwide audience and turned what we now call Brazilian Jiu-Jitsu into one of the fastest growing martial arts on the planet. The Gracie lineage remains one of the most respected in the sport, and many academies trace their teaching back to it.
BJJ is best understood as a system of positions. A match or a roll (the term for live sparring) is a constant exchange in which each person tries to improve their position while preventing their partner from doing the same. Once you reach a controlling position, you can hold it, advance to a more dominant one, or attack a submission.
The most distinctive position in BJJ is the guard, where the person on the bottom uses their legs to control and attack the person on top. The guard turns being underneath, which would be a losing position in many martial arts, into an offensive base from which you can sweep, submit, or stand back up. The opponent who tries to get past your legs to a dominant top position is the guard passer, known in Portuguese as the passador, and guard passing is one of the central skills of the art.
From there, dominant positions such as mount, back control, and side control let you immobilise your opponent and hunt for the finish. A submission ends the exchange: it is usually a joint lock, which threatens a joint such as the elbow or shoulder, or a choke, which restricts blood flow or air. When a submission is locked in, the person on the receiving end taps to concede, and it is released immediately. Tapping early and often is simply how everyone trains, and it is what makes hard sparring safe.
BJJ is trained in two formats. In gi BJJ you wear the traditional uniform, a reinforced jacket and trousers with a coloured belt, and you are allowed to grip the fabric. Those grips on the collar, sleeves, and lapels open up a whole layer of control and submissions that slow the pace and reward precision. In no-gi BJJ you train in a rash guard and shorts, there are no clothing grips, and the game tends to be faster and more reliant on body control and underhooks.
Most academies teach both, and the underlying positions are identical, so progress in one carries over to the other. For a full breakdown of the differences, what to wear, and which to start with, see our guide to gi vs no-gi BJJ.
Adult ranks in BJJ run white, blue, purple, brown, and black, with each colour marking a major stage of development. Progress is famously slow compared with other martial arts: reaching black belt typically takes around a decade of consistent training, and promotions reflect genuine skill, mat time, and understanding rather than a fixed timetable. This patient progression is a big part of why a BJJ belt carries so much credibility.

BJJ suits almost everyone, regardless of age, fitness, or background. Because the art rewards leverage and technique over raw athleticism, you do not need to be young, strong, or flexible to benefit. People start in their teens and people start in their fifties, and both can train productively by choosing the right partners and tapping early.
As a self-defence system, BJJ is among the most practical martial arts available, since it teaches you to stay calm under pressure and to control a larger person without throwing a punch. As fitness, a single session is a full-body workout that builds strength, mobility, and cardiovascular conditioning while you are too absorbed in the problem-solving to notice you are exercising. Many people also describe the mental side, the focus and stress relief, as the reason they keep coming back.
Getting started is simpler than most people expect. The first step is to find a reputable gym with qualified instructors and a welcoming beginner programme. Look for a clean mat, structured fundamentals classes, and a culture that lets you train at your own pace. Almost every academy offers a free trial, and they will usually lend you a gi, so you can attend your first session in athletic clothing without buying anything.
Your first class will normally cover a warm-up, some basic movements, a technique or two, and possibly light positional drilling. You are not expected to know anything, and you will not be thrown into hard sparring on day one. Arrive with short, clean nails, stay hydrated, and remember that tapping is part of learning, not a failure.
