The short answer
Two to three days a week, with at least one rest day between sessions for the same muscles, works well for most adults over 40.
A sample week
Monday: full-body strength. Wednesday: full-body strength. Friday or Saturday: optional third session.
Walk or stretch on the other days.
Listen to your recovery
If you're very sore or tired, take an extra rest day. Consistency over months matters more than any single session.
Frequently asked questions
Is one day a week worth it?
Yes — one session is far better than none and a great starting point.
Can I train every day?
You can move every day, but alternate hard strength days with lighter days so muscles can recover.
General education, not medical advice. Check with your doctor before starting a new exercise program.
