How do I keep a BJJ training journal effectively?

A training journal is one of the simplest yet most powerful tools for BJJ improvement. After each class, spend five minutes writing down the techniques covered and the key details you want to remember. Note what happened during rolling, including submissions you caught or got caught in, positions where you felt strong or weak, and any observations about your game. Over time, this creates a searchable database of your BJJ knowledge. Review your journal before class to remind yourself of techniques you want to practice. Weekly reviews reveal patterns, such as consistently getting passed from a certain guard or always failing to finish a particular submission. These patterns become your training priorities. Many practitioners use apps specifically designed for BJJ training logs that let you tag techniques, track training partners, and measure progress. The act of writing itself reinforces learning because it forces you to articulate what you learned, which deepens understanding.
