Belts, exercises, training plan
Write down what the group learns today, and what of it only the green belts do. That is what later tells you who drilled what.

The app in use, recorded.
The club says what its levels are — belts for you, grades elsewhere — and what exercises a session is made of. Neither has to be typed in: a template brings your sport’s belts and techniques in one tap. A member holds a separate level in each of their groups: a yellow belt with the beginners and a white one with the advanced, because the level belongs to the membership, not to the person.
One day, one group, one exercise
The training plan is a calendar: tap a day and put down what the group drills on it. A row is for everyone or for one belt — the kata for the brown belts, the breakfalls for all. A member’s programme for the day is the shared rows plus the rows of their own belt.
Why it is more than a note
What was on the plan, and what the member was there for, they practised. That is what the reports and the On the mat board count, with nothing to tick off during training. The plan can be written after the fact, and the numbers follow at once.
