Master these fundamental concepts to build a solid foundation in Brazilian Jiu-Jitsu. Every roll, every drill, every class—these principles guide your game.
In any defensive position, your hands should be "home" (near your neck). If an opponent controls your collar or neck, they control your posture and have a direct path to a submission.
In almost every position—standing, half guard, or passing—the person with the underhook (placing your arm under theirs to control the shoulder/torso) usually has the offensive advantage. It prevents the opponent from taking your back and gives you a powerful lever for sweeps.
Never leave your arms extended or "floating" away from your ribs. Keeping your elbows glued to your sides makes it much harder for your opponent to isolate an arm for an armbar or Kimura and prevents them from getting underhooks.
Essentially, you want your limbs inside your opponent's limbs. Controlling the "inside channel" allows you to frame, create distance, and prevent your opponent from flattening you out.
When you are inside someone's guard, you must maintain a strong, upright posture. Once your head is pulled down and your spine is bent, you become vulnerable to sweeps and submissions. Conversely, if you are on the bottom, your goal is to "break" the opponent's posture.
Success in BJJ is rarely about pushing with your arms; it's about moving your hips. Whether it's a "shrimp" to create space or a "bridge" to off-balance an opponent, your power comes from the bridge and the escape of the hips.
Unless you are using it for a specific high-level transition, turning your back usually gives your opponent the most dominant position in the sport: back control. Always try to face your opponent's center line.
If you are being crushed, don't use your muscles to push the opponent away—you will tire out quickly. Instead, use your bones to create a "frame" (locking your arms or legs in a braced position). Frames hold weight with minimal effort.
When you are on top, avoid leaving "air" between you and your opponent. Any gap is an opportunity for them to insert a knee or a hand to escape. On the bottom, your goal is to create that air to escape.
The body follows the head. If you can control the direction of your opponent's chin, you can prevent them from turning into you or away from you. This is vital for finishing passes and maintaining side control.
When passing or playing guard, try to maintain at least three points of contact (hands, feet, hooks) on your opponent. This makes your movement reactive and keeps them stuck in your web.
Being flat on your back makes you immobile and heavy. Whether you are in guard or being mounted, you should almost always be on a hip or actively "shrimping." A flat back is a pinned back.
This is a more modern fundamental, especially with the prevalence of leg locks. Leaving your feet dangling or your heels "exposed" is the same as leaving your neck unprotected. Keep your feet active and tucked.
Generally, you shouldn't try to pass a guard with one arm in and one arm out. This is the classic setup for a triangle choke. Either have both arms inside their legs or both arms outside.
This is the golden rule. Never sacrifice a dominant position (like Mount or Side Control) to chase a submission unless you are 100% sure you will finish it. If you lose the submission, you should at least end up in a better or equal position.
Remember the golden rule: master these fundamentals, and the submissions will follow. Every training session is a chance to refine these principles.
