What is Brazilian Jiu-Jitsu? A beginner's guide

The short answer

Brazilian Jiu-Jitsu (BJJ) is a grappling martial art built around ground fighting. Rather than striking, it focuses on taking an opponent down, controlling them on the ground, and finishing with submissions — chokes and joint locks that force the opponent to 'tap out' (surrender) or be rendered unable to continue. Where many martial arts are about hitting, BJJ is about control.

Its defining philosophy is that technique and leverage beat size and strength. A smaller, weaker person, using proper technique, can control and even submit a much larger, stronger opponent — a claim BJJ has backed up publicly and repeatedly, most famously in the early days of the UFC. That promise is a big part of why BJJ appeals to people who assumed martial arts required being big or athletic.

BJJ is practiced both as a sport, with competitions and a ranking system, and as a self-defense system. It's trained in a traditional uniform called a gi, and also without it (no-gi), and it uses a colored belt system to mark progress. The rest of this guide unpacks each of these.

Where BJJ came from

BJJ's roots trace back to Japan. Judo, itself refined from older Japanese jujutsu by Jigoro Kano, contained a ground-fighting component alongside its throws. In the early 1900s, a judo expert named Mitsuyo Maeda traveled the world and eventually settled in Brazil, where he taught members of the Gracie family. The Gracies, especially Helio and Carlos, adapted and emphasized the ground-fighting aspects, developing them into what became Brazilian Jiu-Jitsu.

The Gracies refined BJJ specifically to let a smaller person prevail through technique and leverage — partly out of necessity, as Helio Gracie was famously slight. They tested and proved the art through open challenge matches against practitioners of other styles, building its reputation the hard way, against genuine resistance.

BJJ then exploded onto the global stage in 1993, when Royce Gracie, a relatively small man, won the first Ultimate Fighting Championship by submitting much larger opponents from other martial arts. That single event demonstrated the effectiveness of ground fighting to the world and launched BJJ's global growth into the enormously popular art it is today.

How BJJ works

The core logic of BJJ is a hierarchy of positions. A match typically progresses from standing, to a takedown, to a series of ground positions that range from bad (being controlled underneath) to good (controlling from on top or the back). The goal is to improve your position, control your opponent, and eventually reach a position from which you can apply a submission.

Submissions are the finishing moves: chokes that cut off blood or air, and joint locks that threaten to hyperextend or twist a joint. When one is applied and inescapable, the opponent taps — signaling surrender — and the match ends. Tapping is fundamental and healthy: it lets practitioners train these dangerous techniques safely, resetting and going again rather than getting injured.

Uniquely, BJJ teaches you to be effective even from your back, through a set of positions called the guard. Where most grappling treats being underneath as losing, BJJ turns it into an offensive platform from which you can sweep, control, and submit. This guard game is one of BJJ's signature contributions to martial arts.

Gi and no-gi

BJJ is trained in two main formats. In the gi, practitioners wear a heavy cotton jacket, pants, and a belt, and the fabric itself becomes part of the game — you can grip the collar, sleeves, and pants to control and submit your opponent, including collar chokes that use the gi. Gi BJJ tends to be slower and more control-oriented because grips allow tight control.

In no-gi, practitioners wear a rashguard and shorts or spats, and there's no fabric to grip. Control comes from body positioning, underhooks, and grips on the body rather than clothing. No-gi is generally faster and more scramble-heavy, and some techniques differ because the gi's grips and friction are absent.

Most gyms offer both, and many practitioners train both because they reinforce each other — the gi sharpens detail and control, no-gi sharpens speed and scrambles. Beginners are often advised to start in the gi, where the slower pace makes fundamentals easier to learn, though either is a valid entry point. Our guide on gi vs no-gi covers the choice.

The belt system

BJJ marks progress with a colored belt system. For adults, the belts run white, blue, purple, brown, and black, and progression is famously slow — each belt represents a substantial leap in skill, and reaching black belt takes around a decade of consistent training on average. This slow progression is deliberate: the belt reflects demonstrated skill against resisting opponents, not just attendance.

Between belts, many gyms award stripes as smaller markers of progress, and there are additional degrees on the black belt, plus rare coral (red-and-black) and red belts at the highest levels for decades of contribution to the art. Kids have their own additional belt colors before they can earn adult ranks.

The slow, earned nature of BJJ ranks is part of the culture — a blue belt is already a capable grappler, and a black belt is a serious achievement. We cover the full system in our belt ranks guide, and you can get a realistic sense of timelines with our belt timeline estimator.

Sport BJJ and competition

As a sport, BJJ has a thriving competition scene governed by organizations like the IBJJF, with tournaments for every belt, age, and weight division. Sport matches are scored by improving position — takedowns, sweeps, guard passes, and reaching dominant positions like mount and back control all earn points — and can be won by submission or on points.

There's also a large no-gi and submission-grappling scene, epitomized by events like ADCC, which emphasize finishing. Competition isn't mandatory — plenty of people train purely for fitness, self-defense, or fun — but it's a popular way to test your skills under pressure and accelerate your development.

If competing appeals to you, understanding the rules, weight classes, and scoring is the first step. Our tools and guides cover all of it — from the points system to weight divisions — and our first competition guide walks you through preparing.

Why people love it

BJJ's popularity comes from a rare combination of benefits. It's a genuinely effective martial art and self-defense system, a superb full-body workout, and an endlessly deep intellectual puzzle often called 'physical chess' — there's always another layer to learn, which keeps people engaged for decades. Few activities are simultaneously this practical, this good for fitness, and this mentally absorbing.

It's also uniquely social and humbling. The live sparring — rolling — builds tight-knit communities and a culture of mutual respect, since you can't fake your way through training against resisting partners. That humility and camaraderie keep people coming back, and the mental benefits — stress relief, confidence, resilience — are as valued as the physical ones.

And it's accessible: adults start every day, at every age and fitness level, and the leverage-over-strength premise means you don't need to be big or athletic to begin. That combination — effective, healthy, absorbing, social, and accessible — is why so many people who try BJJ end up hooked for life.

How to get started

Starting is simpler than it looks. Find a reputable gym, take a trial class (most offer one free), and expect to borrow a gi for your first sessions. You'll need very little to begin — a gi or a rashguard and shorts, a mouthguard, and flip-flops — and you don't need to be fit or flexible first; you get in shape by training.

Expect to be a beginner for a while, to get controlled by more experienced people, and to improve slowly but steadily. Tapping early, showing up consistently, and focusing on survival and fundamentals over flashy moves is the path that works. The first few months are the hardest, and getting through them is mostly about persistence.

Everything you need to begin — what to buy, what to expect, and how to survive your first months — is in our getting started hub. BJJ rewards the people who simply keep showing up, so the most important step is the first one: walking through the door.
