Reframe A Fitness Plateau As Normal Not Failure

The numbers were climbing steadily for two months and now they have flatlined and it feels like all that progress has quietly reversed itself. This explains why plateaus are a normal, expected part of training rather than a warning sign, and gives you one specific suggestion for actually moving past this particular one.

Help me reframe a fitness plateau I have hit after a period of good progress. I will describe what my progress looked like before and what has stalled. Explain, based on general training principles, why plateaus are a normal and expected part of progress rather than a sign that something has gone wrong. Then give one specific, evidence-informed suggestion for breaking through this particular type of plateau based on what I have described. Situation: {PLATEAU_DETAILS}
