Progressive overload
Progressive overload is the gradual increase in training demand over time — more weight, more reps, more sets or better control — and it is the requirement that makes a training programme produce adaptation.
Muscle and strength adapt to demands that exceed what the body is currently comfortable with. Repeat the same session indefinitely and the body has no reason to change. Progressive overload is the name for making sure something goes up.
The levers, roughly in order of usefulness
Load. More weight for the same reps. The clearest signal and the easiest to record.
Reps. Same weight, more repetitions. Usually how you bridge the gap before a load increase is possible.
Sets. More total work per muscle per week, useful up to a point and then increasingly expensive in recovery.
Quality. Better range of motion, more control, less assistance from momentum. Real progress that a log records badly, which is why it is worth a note.
Density. The same work in less rest.
Why a log is not optional
Overload is a comparison with last time, and nobody remembers last time accurately. Without a written record, "a bit more than before" drifts into "about the same" over a couple of months, which is the most common reason a person trains consistently for a year and looks unchanged.
What it does not mean
It does not mean adding weight every session. Progress in a trained lifter is measured in months, and a week where nothing goes up is data, not failure.
