Track fitness progress without obsessing

Help me track fitness progress simply.

What I do: [walks, gym, runs]
Metrics I care about: [consistency, distance, how I feel — not medical data unless my clinician asked]
How often I'll log: [daily/weekly]
Tool: [notes / Sheets / app I already have]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Three metrics max.
2. A simple log layout.
3. A fortnightly review ritual.
4. What not to obsess over.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent diagnoses, doses, calorie targets or treatment plans. UK English.
