What Is Brazilian Jiu Jitsu? Everything You Need to Know
Share
The Short Version
Brazilian jiu jitsu is a grappling martial art that focuses on ground fighting and submissions. No punching. No kicking. Instead, practitioners use leverage, body mechanics, and technique to control opponents and force them to submit through joint locks (bending a limb past its natural range of motion) or chokes (restricting blood flow to the brain).
The defining principle of BJJ is that a smaller, weaker person can defeat a larger, stronger one through superior technique and positioning. That's not marketing language. It's the foundational concept that the entire art is built around, and it's been proven repeatedly in competition and real-world scenarios since the sport's inception.
If you've heard someone in your life talk about "rolling," "submissions," "guard," or "passing," they train BJJ. And what follows is everything you need to know about what they're doing and why they can't stop talking about it.
How BJJ Works
The Goal
In a BJJ match or sparring session (called "rolling"), the goal is to control your opponent and achieve a submission, a position where you've applied a joint lock or choke that forces them to "tap" (physically tap their hand on the mat, on their opponent, or verbally say "tap") to signal they give up. Tapping is how the sport stays safe. When someone taps, you release immediately. That's the universal rule.
Positions
BJJ has a hierarchy of positions, each representing a different level of control:
Mount — You're sitting on top of your opponent's torso. This is one of the most dominant positions in BJJ. The person on bottom has very limited options.
Back control — You're behind your opponent with your legs wrapped around their waist (called "hooks"). This is arguably the most dominant position because the person being controlled can't see what's coming.
Side control — You're lying across your opponent's torso from the side, pinning them with your chest weight. A strong control position with many submission options.
Guard — You're on your back with your opponent between your legs. Despite being on bottom, this is not a losing position in BJJ. The guard is one of the most developed and sophisticated areas of the sport, with dozens of variations (closed guard, open guard, half guard, butterfly guard, and many more). A skilled guard player is dangerous from their back.
Turtle — A defensive position where you're on all fours, protecting your neck and limbs. It's a transitional position, not a place you want to stay long.
Submissions
Submissions are how you "win" in BJJ. They fall into two broad categories:
Joint locks — Techniques that hyperextend or rotate a joint past its natural range of motion. The most common targets are the elbow (armbar, kimura, americana), shoulder (kimura, omoplata), and knee/ankle (heel hook, kneebar, ankle lock). When applied correctly, a joint lock causes immediate pain and risks injury if the opponent doesn't tap.
Chokes — Techniques that restrict blood flow to the brain by compressing the carotid arteries on both sides of the neck. The most common chokes include the rear naked choke (applied from back control), the triangle choke (applied from guard using the legs), and the guillotine (applied from the front). A blood choke causes unconsciousness in approximately 8-12 seconds if the opponent doesn't tap.
Gi vs. No-Gi
BJJ is practiced in two formats:
Gi ("with the uniform") — Practitioners wear a gi, which is a thick, durable jacket and pants with a belt indicating rank. The gi adds an entirely new dimension to grappling because you can grip the fabric, collars, sleeves, pants, to control your opponent and set up submissions. Gi jiu jitsu tends to be more methodical and technical, with an emphasis on grip fighting and precise positioning. If you're shopping for a gi, our gi sizing guide explains how the unique sizing system works.
No-gi ("without the uniform") — Practitioners wear a rash guard (compression top) and shorts or spats (compression pants). Without the gi fabric to grip, no-gi relies more on body control, underhooks, overhooks, and wrist control. No-gi tends to be faster-paced and more scramble-heavy than gi training.
Most BJJ academies offer both formats, and many practitioners train in both. Some prefer one over the other, but the fundamentals transfer between them.
Who Trains BJJ
One of the most distinctive things about Brazilian jiu jitsu is the diversity of its practitioners. Walk into any BJJ academy and you'll find a cross-section of society that rarely exists in other settings: lawyers rolling with plumbers, teenagers training with retirees, software engineers drilling with nurses.
The mat is genuinely egalitarian. Your job title, income, education, and social status mean nothing when someone has your back. What matters is effort, consistency, and willingness to learn. That democratic quality is one of the main reasons people fall in love with the sport and stay for years.
BJJ is practiced by men, women, and children of all ages. Kids' programs are common at most academies, and the art is increasingly popular as a fitness practice for adults who have no interest in competition or fighting but want a challenging, engaging physical practice.
Why People Start BJJ
People come to BJJ for different reasons, and they often stay for different reasons than the ones that brought them in:
Self-defense. BJJ was designed as a self-defense system, and it remains one of the most practical martial arts for real-world situations. The ability to control someone on the ground without striking is particularly valuable.
Fitness. A single BJJ session burns significant calories, builds functional strength, improves flexibility, and develops cardiovascular endurance. It's a full-body workout disguised as a skill-learning session, which makes it more engaging than traditional exercise for many people.
Mental health. Training BJJ requires total presence. You can't think about work, bills, or stress when someone is trying to choke you. Many practitioners describe the mat as a form of moving meditation, the one hour a day where the outside world disappears completely.
Community. The bonds formed through BJJ are unusually strong. Training partners share a physical and emotional experience that creates deep trust. Many practitioners describe their gym as a second family.
Competition. For the competitively driven, BJJ offers a structured tournament circuit with events at every level, from local novice to international professional.
The Belt System
BJJ uses a belt ranking system with five adult ranks: White, Blue, Purple, Brown, and Black. The typical journey from white to black belt takes 8-15 years of consistent training, significantly longer than most other martial arts. Each belt is earned through sustained effort and coach evaluation, not standardized testing. Belts are never purchased as gifts; they're awarded by coaches based on demonstrated skill and dedication.
What a Typical BJJ Class Looks Like
Classes vary by academy, but most follow a similar structure:
Warm-up (10-15 minutes). Jogging, stretching, and BJJ-specific movement drills: shrimping (a hip escape movement), bridging, technical stand-ups, and basic tumbling.
Technique instruction (20-30 minutes). The coach demonstrates a specific technique or series of techniques, then students pair up and drill them with a cooperative partner. This is the learning portion of class.
Sparring / Rolling (20-30 minutes). Students pair up and grapple live, applying what they've learned against a resisting partner. Rounds typically last 5-6 minutes with brief rest periods between. This is where the real learning happens, under pressure, against someone who's trying to do the same thing to you.

The Culture
BJJ has a culture that's distinct from most other sports and martial arts. It's built on mutual respect, humility, and a shared understanding that everyone on the mat is voluntarily doing something difficult together.
The culture values consistency over talent, technique over strength, and showing up over showing off. Ego is systematically dismantled through the daily experience of being submitted by people who are better than you, and that process of ego dissolution is considered a feature, not a bug.
The BJJ community also has a strong sense of humor about itself. The inside jokes, the memes, the shared suffering, it all creates a culture that bonds practitioners together in a way that extends well beyond the mat. Brands like Holiday BJJ exist specifically because that culture is strong enough to sustain its own identity, its own humor, and its own traditions.
Final Thoughts
Brazilian jiu jitsu is a martial art, a fitness practice, a mental health tool, a competitive sport, and a community, often all at the same time for the same person. It's hard, humbling, endlessly deep, and the reason someone in your life keeps coming home sore, covered in bruises, and somehow happier than when they left.
If you're thinking about starting, every academy offers a free trial class. Walk in. Try it. Get confused. Get submitted. Come back the next day. That's how it starts for everyone.
And if someone you love already trains, now you understand a little more about what they're doing and why it matters to them. That understanding is worth more than you'd think. For gift ideas for the grappler in your life, browse our complete jiu jitsu gift guide.
