What Is Open Mat?
Open mat is a session with no instructor-led technique or drilling. Mats are open, partners choose each other, and everyone trains at their own pace. Some gyms hold open mat weekly; others offer it as a drop-in option for students from other schools.
Open Mat Etiquette
- Ask, don't demand: Approach someone and say "Would you like to roll?" β accept a "no" gracefully.
- Match your partner's intensity: If a higher belt rolls light with you, don't go 100%.
- Tap early, tap often: Open mat is not the place to ego-protect submissions. Tap and learn.
- No coaching during the roll: Save feedback for after the round, not during.
- Clean gear: Wash your gi/rash guard. Open mat brings people from various schools.
- Respect the clock: When time is called, stop β don't keep going for "just one more second".
Who Should You Roll With at Open Mat?
Higher Belts
Rolling with higher belts reveals your gaps. You'll be submitted β that's the point. Pay attention to how they get to those positions, not just the submissions themselves.
Same Level
Competitive rolls where both people are pushing. Good for competition prep and testing techniques under pressure.
Lower Belts
Rolling with lower belts lets you work specific techniques without full pressure. Try to set up that armbar from mount 10 times rather than just winning.
What to Work on at Open Mat
- Weak areas: If you always get your guard passed from the same side, work that.
- New techniques from recent classes β try them in live rolling.
- A specific submission entry chain you want to build.
- Defensive drilling: give up bad positions and practice escaping.
Visiting Other Gyms' Open Mats
Many gyms welcome visiting students. If you visit another school's open mat:
- Introduce yourself to the instructor first.
- Be humble β you're a guest. Even if you're a higher belt, roll controlled.
- Don't go hard against beginners at a gym you're visiting.
- Leave your ego at the door β getting tapped by a local is normal.

More Questions
What is BJJ open mat and why should I go?
Open mat is a dedicated time at your academy where students of all levels can come to roll (spar) with each other. It's an excellent opportunity to practice techniques learned in class, test your skills against different body types and styles, and get extra mat time without the pressure of a formal class.
What should I bring to open mat?
You'll need your gi (if training gi), a water bottle to stay hydrated, and potentially a small towel. Some people also bring a change of clothes for after training. Most importantly, bring a positive attitude and a willingness to learn and roll.
How should I behave during open mat?
Be respectful of everyone on the mats. Tap early and often if you're caught in a submission. Communicate with your rolling partners, especially if you're trying a new technique or if something feels uncomfortable. Avoid ego-driven rolling; the goal is to improve, not to 'win' every roll.
