Resistance training 2–3 times per week regardless of age

Resistance training drives muscle protein synthesis and reverses sarcopenic muscle loss even in people in their 80s and 90s.

Why it works

The anabolic response to resistance training (increased MPS, muscle fiber hypertrophy) is preserved with aging, though it may require higher volumes than in younger adults due to "anabolic resistance" — a blunted per-unit-stimulus response. Studies of resistance training in very old adults (80s, 90s) consistently find meaningful strength and mass improvements, contradicting the assumption that the window closes. The key is consistency and progressive overload, not the modality.

How to do it

1. Train the major muscle groups (legs, back, chest, shoulders) 2–3 times per week, with at least one rest day between sessions.
2. Use a load where the last 2 repetitions of each set are genuinely challenging (roughly 70–80 % of maximum).
3. Prioritize compound movements (squat, press, row, hinge) — they recruit the most muscle per unit time.
4. Adapt the modality if needed (machines over free weights if balance is a concern) but do not reduce the progressive overload principle.

Evidence

Meta-analyses of resistance training in older adults (60+) consistently find significant improvements in muscle mass, strength, and functional capacity, with no age ceiling identified for the response to training. (rct)

Studies are largely short (12–24 weeks). Very old individuals (90+) benefit from training but require careful supervision; some starting conditions (severe dynapenia, fall risk) require physiotherapist-supervised entry.

Common mistake

Reducing to very light weights and high reps as you age to "protect the joints." Light, non-challenging resistance does not drive MPS or reverse sarcopenia; load is the required stimulus.
