Plan a simple strength add-on for runners

Plan a simple strength add-on for running.

Weekly running: [rough]
Niggles: [optional]
Kit: [bodyweight / gym]
Minutes available: [number]

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

Then:
1. A twice-weekly short session outline.
2. How to fit it around runs.
3. Stop rules; see physio/GP for persistent pain — don't invent rehab.
4. NHS activity pointer.

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. This is help with preparation, planning and wording, not medical, diet or treatment advice; check the NHS website, speak to a pharmacist, or contact NHS 111; call 999 if it feels like an emergency.
