A useful session note starts before the details fade.

Capture completed exercises and exact numbers first. Then add technique observations, anything to watch, and the next-session plan. Keep private context separate from the short message a client receives.

Use a repeatable order

Performance → observations → watch items → next session. A consistent structure makes each client’s history easier to scan without forcing you to fill in a complex workout tracker.

Do not fill gaps from memory

If a load, unit or result is uncertain, mark it for confirmation. A clean blank is more useful than a confident but incorrect number.
