Is it really safe to start strength training in my 60s or 70s?

Yes. Research consistently shows safe and effective strength gains in adults starting in their 60s, 70s, 80s, and beyond. The key is starting at an appropriate level - bodyweight exercises or very light resistance - and progressing gradually. If you have health concerns, a conversation with your GP before starting is sensible, but the vast majority of people are cleared for strength training with appropriate modifications.

Will strength training raise my blood pressure?

Blood pressure temporarily rises during any exertion, including walking up stairs. Regular strength training actually helps lower resting blood pressure over time. The key is breathing properly (do not hold your breath) and avoiding extremely heavy loads. If you take blood pressure medication, inform your GP that you are strength training so they can monitor accordingly.

How long before I notice a difference?

Strength improvements typically appear within 2-3 weeks - exercises feel easier, daily tasks become less effortful. Visible muscle changes usually take 6-8 weeks of consistent training. The functional improvements (carrying shopping, climbing stairs, getting up from chairs) often arrive before any mirror changes, and they are the improvements that matter most.
