General guidance for adults. Research findings and practical examples are distinguished below.
Why It Matters
Standing from a chair, climbing stairs and carrying a bag are useful measures of capability. Strength training aims to preserve those options, not only to change appearance.
What the Evidence Shows
The LIFE randomized trial enrolled 1,635 inactive adults aged 70–89 with physical limitations who could initially walk 400 m. Over an average 2.6 years, a combined walking, resistance and flexibility program reduced major mobility disability compared with health education (30.1% vs 35.5%; hazard ratio (HR; a comparison of event rates over follow-up) 0.82, 95% confidence interval (CI; a range expressing statistical uncertainty) 0.69–0.98). This supports a combined program, not strength training alone. [1]
What You Can Do
- Reserve at least 2 days/week for major muscle groups. A beginner can learn a chair rise, wall push-up and supported pulling exercise with suitable instruction; these examples are a starting selection, not a complete whole-body program. [2] [3]
- For resistance exercises, one set of 8–12 controlled repetitions can be effective. Choose effort that is challenging toward the end without losing technique; start lighter if necessary and progress gradually. [3]
- Older adults: add balance-focused activity on at least 3 days/week as part of a varied program. Use a stable support and instruction if at risk of falling. Record whether everyday tasks become easier over time. [2]
What to Consider
Pain, recent surgery, unstable disease or repeated falls require an adapted plan. In LIFE, serious adverse events were common in both groups (49.4% vs 45.7%; risk ratio (RR) 1.08, 95% CI 0.98–1.20); this was a vulnerable older population. Do not interpret the mobility result as proof that any unsupervised exercise is risk-free. [1]
