Check the standard first

Compare range, tempo, setup, and rest timing with the sessions that established the baseline. Apparent progress can disappear when the standard drifts.

If the standard is stable, check whether all exercises stalled or only one.

Change one variable

Restore a little rest, remove a set, or choose a more stable exercise. Do not change load, volume, frequency, and technique at once.

A small reset can create another long runway of density progress.
