The short answer
Track progressive overload by comparing the same exercise over time. Look at weight, reps, sets, and total volume. If one of them improves while form stays solid, you have a useful signal.
Compare the same lift
Bench Press and Incline Dumbbell Press both train pressing strength, but they are not the same thing. Compare Bench Press to Bench Press. Compare rows to the same row variation.
Look for small wins
Progressive overload can mean 2.5 kg more, one extra rep, one extra set, better control, or the same work with less effort. The log should make those small wins easy to notice.
Do not force records every workout
Some days are maintenance. Some days are practice. Some days are heavy. A useful log keeps all of them, so you can see the bigger pattern instead of judging one session in isolation.
Use volume when weight stalls
If your top weight is stuck, volume can show progress. A lifter who moves the same weight for more quality reps is still building capacity.
