How to Take BJJ Notes You Will Actually Use

A BJJ journal fails when it becomes a transcript of classes. Two short lists, the positions beating you and your current answer to each, do the job in a fraction of the writing and get re-read.

Almost everyone tries a jiu-jitsu notebook. Almost everyone abandons it around week five. The reason is consistent: the notes get written and never read, so writing them stops feeling worth the fifteen minutes.

The fix is not more discipline. It is writing something different.

Why class transcripts fail

A transcript looks like this: "Knee cut pass. Step 1, establish cross grip. Step 2, break the leg down. Step 3..."

Three problems. It takes a long time to write, it is unreadable a month later without the memory that produced it, and it is organised by what the coach taught rather than by what you need. You end up with a chronological record of a gym's curriculum, which is not your curriculum.

There is also a retrieval problem. Writing a technique down does not make it available under pressure. It only feels like it does, which is why forgetting between classes needs a system rather than a record.

The two lists

Replace the notebook with two lists, both short enough to fit on one page.

List one: the problems. Three to five positions that are currently beating you. Positions, not techniques. "Someone knee cuts me and I flatten out." "I get stuck under side control with a heavy crossface." "I give up my back escaping mount."

List two: the answers. For each problem, one line: the response you are committed to using right now, and the tell that triggers it. "Knee cut: shin across and underhook, when their weight comes forward." Not three options. One, until it works or clearly does not.

That is the whole system. It fits on a phone note, it takes two minutes to update after class, and unlike a transcript, you will actually open it, because it is short and it is about you.

Writing the line after class

The most valuable thirty seconds in your week is the one right after training, before you shower.

Write one sentence: which position beat you and what you tried. Nothing else. No techniques of the day, no philosophy.

Do that for a month and the problem list writes itself, in your own words, with frequencies attached. The position that appears eight times is your curriculum for the next block, and you did not have to guess.

Turning notes into practice

Notes only help if they feed something. Two uses, both cheap.

Before class, read the answer list. Thirty seconds. It sets what you are looking for in the rolls, which turns a random session into a session with a question in it.

Between classes, run the problems as decisions. Position, commit to your answer, check it. A few seconds each, most days. That converts a written note into retrieval practice, which is the part that shows up under pressure, and it is exactly what studying off the mat is for.

Where to keep them

Paper or phone, it barely matters. What matters is that it is with you after class and openable before class.

A few things that reliably help regardless of medium: date the problem list each time you rewrite it, so you can see what moved. Keep old versions rather than editing over them; the deleted problems are the only progress report jiu-jitsu gives you. And keep the whole thing on one screen, because a note that requires scrolling is a note you stop reading.

When to write more

There are two moments where longer notes pay off.

Seminars. You will not remember six hours of material and you know it. Write the concepts and the details that surprised you, not every step, and pick two things to actually use.

Private lessons. The value is the personalised correction, and it fades fast. Write what your coach said was wrong with what you were doing, verbatim if you can, because that is the part you cannot reconstruct from a video.

Even then, the goal is the same: translate it, within a day, into your two lists. A seminar you enjoyed and never turned into a problem-and-answer line is entertainment.

BJJ notes questions

Should I take notes after every BJJ class?

One line after each session is enough: which position beat you and what you tried. That single sentence does more than a full write-up, because it builds a list of your actual problems rather than a record of the gym's syllabus.

What is the best way to organise BJJ notes?

By position rather than by date or by technique name. Rolls happen in positions, so notes organised by position are retrievable when you need them. A chronological log of classes is almost never opened again.

Should I write down every technique I learn?

No. Most techniques taught in class are not the ones you need next, and writing all of them costs enough time that people stop. Write the ones that answer a position on your problem list.

Do BJJ notes actually improve your jiu-jitsu?

They help when they are used as inputs to practice rather than as an archive. Reading your answer list before class and rehearsing your problem positions between sessions is what produces the improvement; the writing itself is only the setup.

How often should I review my BJJ notes?

The answer list, briefly, before class. The problem list, once a month, rewritten from scratch so you can see which positions dropped off. Anything more frequent turns into busywork.

A list you actually re-read.
