How Long Should a Training Journal Entry Be?

Short. A good training journal entry takes 60-90 seconds and fits in a few lines. Two ratings (effort and session quality, both 1-10), one or two sentences about what you noticed, and a brief intention for next time. That's a complete entry.

Why shorter is better

The biggest reason athletes quit journaling is that it takes too long. If your entries require five minutes of writing after a hard session, you'll do it for a week and stop. The journal that works is the one you'll actually use when you're tired, sore, and want to go home.

Shorter entries are also more useful in the long run. When you look back over weeks of training, concise notes are easier to scan and compare than long paragraphs. "Guard retention was sharp today, recovered position twice from half guard" tells you more at a glance than three paragraphs about the same session.

What counts as "enough"

On your best days: two ratings, what worked, what to adjust, and an intention for next time. Maybe four or five lines total.

On your worst days: just the two ratings. Effort and quality. That's still a useful data point, and it keeps the habit alive without demanding anything from you when you have nothing to give.

The range between those two is your whole system. Some days you write more, some days less. Both count.

Make it easy on yourself

The format matters more than the length. Having the same few prompts every time means you never have to decide what to write. You just answer the questions and move on.
