Keep the target stable
Track the same exercise, load, reps, and effort consistently enough to compare sessions. If technique or range changes, the number alone is not a clean progression signal.
Use a rep range
Choose a range such as 6–8 reps. Add reps while form stays stable; once all working sets reach the top, make the smallest sensible load increase and build again.
Compare the whole performance
A single personal record is useful, but total reps, set quality, effort, and recovery explain whether the session truly improved.
Let the log make the next step obvious
Previous sets should be visible during the workout. The goal is not to remember every number—it is to know what a small, realistic win looks like today.
