The notebook nobody keeps
Every serious strength athlete logs their lifts. Runners track their miles. Swimmers know their splits to the hundredth. But walk into any BJJ gym and ask who tracks their training, and you'll get blank stares.
The excuse is always the same: "BJJ is too complex to track." And yeah, a roll isn't a deadlift. There's no single number that captures what happened. But that's exactly why tracking matters more, not less.
What changes when you start logging
The first thing that happens is you notice patterns you were blind to. You realize you haven't worked from top position in two weeks. You see that your submission rate from mount is 3x higher than from guard. You discover that your worst sessions all fall on days after poor sleep.
None of this is revolutionary. It's just data you already had but never collected.
What to log
Keep it simple. After every session:
- Type: gi, no-gi, open mat, drilling, competition
- Duration: how long you were on the mat
- Rounds: how many rolls or positional rounds
- Key positions: where you spent time, what worked, what didn't
- One sentence: the single most important thing from the session
That takes under a minute. If you can't do a minute, you can voice log on the drive home — talk for 30 seconds and let transcription handle the rest.
