Every BJJ gym has a culture, and most of the rules aren’t posted on the wall. Some of these are universal across gyms. Others vary by school. All of them will help you avoid being “that person” everyone dreads rolling with.
Hygiene (The Most Important Section)
This comes first because it matters more than everything else combined. Poor hygiene isn’t just unpleasant; it’s a health hazard.
- Wash your gi after every session. A gi worn twice without washing is a breeding ground for staph, ringworm, and other skin infections. No exceptions.
- Trim your nails. Fingernails and toenails, before every class. Long nails scratch and cut your training partners. This is the number one hygiene complaint in every gym.
- Shower before class if possible. At minimum, put on fresh training clothes.
- No shoes on the mat. And no bare feet off the mat. Wear flip-flops or slides to and from the training area, especially in bathrooms. The mat is a shared surface.
- Cover any open cuts or wounds with tape or bandages before training.
- If you have a skin infection, stay home. Ringworm, staph, impetigo: these spread through skin contact. Training with an active infection puts everyone at risk. No one will be upset that you took a few days off to heal.
On the Mat
Before Class
- Be on time. If your gym lines up to bow in, be there for it. Arriving late and walking onto the mat during instruction is disruptive.
- Remove all jewelry. Rings, necklaces, earrings, watches, bracelets. All of it. Even a smooth wedding band can pinch skin or catch a finger.
- Bow when stepping on the mat if your gym does this. Watch what the other students do on your first day and follow their lead.
During Drilling
- Pay attention when the instructor is demonstrating. Don’t talk to your partner, check your phone, or drill something different from what’s being taught.
- Be a good drilling partner. Give appropriate resistance when asked, but don’t turn drills into live sparring. The point is for both of you to learn the technique.
- Ask questions. If you don’t understand a technique, ask. Instructors would rather answer a question than watch you drill something wrong for ten minutes.
During Rolling (Sparring)
- Tap early, tap often. If something hurts or you’re caught in a submission, tap. Tapping is not losing; it’s how you train safely for decades. Tap with your hand on your partner, on the mat, or verbally say “tap.”
- Respect the tap immediately. When your partner taps, release the submission right away. No extra squeeze, no “finishing the rep.” Instant release.
- Match your intensity to your partner. If you’re rolling with someone smaller or less experienced, dial it back. If you’re rolling with someone bigger and more experienced, you can push harder. Reading the room is a skill.
- Don’t coach during rolls unless someone asks. Rolling is practice time, not teaching time. If you notice something, mention it after the round.
- Stay in your area. Be aware of other pairs rolling around you. If you’re about to crash into another pair, stop, reset to open space, and continue.
- Don’t slam. Even if you can pick someone up, slamming them onto the mat is dangerous and not acceptable in training at virtually any gym.
- It’s okay to say no to a roll. You don’t owe anyone a roll. If you’re tired, injured, or uncomfortable, a simple “I’m going to sit this one out” is enough.
Belt and Rank Etiquette
- Don’t ask for promotions. Your instructor knows where you are. Asking when you’ll get your next belt is considered bad form.
- Line up by rank if your gym does this (usually highest belt on the left). Watch and follow what others do.
- A belt doesn’t define how you roll. A strong white belt can give a blue belt problems. A small purple belt can tap a big white belt. Rank reflects time, knowledge, and overall development, not just who taps who.
- Don’t wash your belt if you don’t want to. There’s a superstition in BJJ about not washing your belt. Some people follow it, some don’t. Either way, nobody will check.
Social Etiquette
- Introduce yourself to new people. Especially if you’ve been at the gym awhile. New students are often nervous, and a simple “hey, I’m [name], welcome” goes a long way.
- Don’t give unsolicited advice to higher belts. If a purple belt gets caught in your submission, they don’t need you to explain what happened.
- Be careful with advice to lower belts too. Unless your instructor asks you to help, wait until someone asks you for feedback. Everyone processes training differently.
- Keep ego off the mat. You will get tapped. By people smaller than you, newer than you, and less athletic than you. This is normal. The faster you accept this, the faster you’ll learn.
- Thank your training partners after rolling. A handshake or fist bump after a round is standard. These people are helping you get better by lending you their body to practice on.
Gym-Specific Rules
Every gym is different. Some things to figure out in your first week:
- Does the gym bow on and off the mat? Follow the room.
- Can you roll before class starts, or only during designated sparring time? Ask.
- Does the gym allow heel hooks or other “advanced” submissions for white belts? Many don’t.
- What’s the protocol for asking a higher belt to roll? In some gyms, higher belts choose their partners. In others, anyone can ask anyone. Watch and learn the culture.
- Is cross-training at other gyms acceptable? Most modern gyms have no issue with this, but some traditional schools prefer loyalty. Better to know upfront.
The One Rule That Covers Everything
Be someone people want to train with. Show up clean, be respectful, roll with control, check your ego, and be kind to everyone regardless of belt color. Do that, and you’ll be welcome at any gym in the world.
