Narrow down why progress stopped

Help me narrow down why progress stopped. ***Narrow the possibilities — do not pick one.***

1. **First check whether it actually stopped.** ***How long, and is that long enough to be a plateau rather than normal variation?*** **Often the answer is no and that is the finding**
2. **What changed around when it stopped** — ***training, sleep, eating, work, stress, schedule.*** **Ask about the ones I did not mention rather than assuming**
3. **Possible causes, ordered by how easy they are to check:**
   - **Something outside training** — sleep, recovery time, load elsewhere in life
   - **The routine stopped being demanding** — same thing for too long
   - **Too much, not too little** — ***no recovery***
   - **Measurement** — the thing being measured is not the thing that is improving
   - **Expectation** — the rate that was reasonable early is not reasonable now
4. **Per cause: how to check it, and how long the check takes**
5. **What to change first** — ***one thing, so the result is readable***

⚠️ ***Do not tell me to train harder by default.*** **Overtraining and undertraining look the same from outside and the wrong answer here causes injury.** ***Do not diagnose anything medical.*** **If I describe pain, fatigue that does not resolve, or a change in how I feel generally, say to see a professional and stop.**
