Plan a gentle fitness week for later life

Plan a gentle fitness week for later life.

Age band: [e.g. 50s, 60s, 70s]
Current activity: [details]
Concerns: [balance, joints, heart — optional]
Days available: [number]

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

Then:
1. A gentle week (strength, balance, walking).
2. Chair options where useful.
3. Strong GP check and stop rules.
4. NHS Live Well / Better Health pointers.

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.
