Stronger muscles help preserve everyday function as you age.

**The number:** Muscle strengthening on at least 2 days per week ([CDC, 2023](https://www.cdc.gov/physical-activity-basics/guidelines/adults.html))

## The evidence

- Evidence grade: A. Grade A: meta-analyses of randomised trials, or a major guideline consensus.
- Basis: CDC activity guideline and NHS strength guidance reviewed in 2026
- Outcome: recommended minimum frequency of major muscle strengthening
- Comparison: adult weekly activity guidance
- Impact: 86/100. The impact score is an editorial prioritization heuristic for the general list, not a validated estimate of your personal risk.

## Why it matters

Resistance exercise makes muscles work harder than usual, improving strength and endurance. Strength work helps maintain everyday function and slows age related muscle and bone loss. Guidelines recommend training all major muscle groups on at least two days each week.

## How to do it

1. Use weights, resistance bands or your body weight.
2. Include movements for legs, hips, back, abdomen, chest, shoulders and arms.
3. Choose resistance that makes the last repetitions challenging while you keep control.
4. Start gradually and increase resistance when the current level becomes easy.

## Talk to a clinician first

Ask a physiotherapist for adaptations if pain, injury or a health condition limits your movement.

## Putting it into practice

### Start now

- 5 minutes: Read the NHS strength routine and identify a stable chair or wall you could use; if pain or limited mobility makes a move uncertain, note it for a physiotherapist.
- 15 minutes: Try three NHS beginner moves slowly: sit-to-stand from a stable chair, calf raises holding it, wall press-ups. Stop if it hurts.
- 30 minutes: Do the full NHS strength routine slowly with rests between moves, then put your second session of the week in your calendar.

### What it looks like

- Use a wall press-up as a beginner option if you can stand comfortably and it suits your joints.
- A solid chair without wheels can support sit-to-stand practice when that movement is suitable for you.
- You can use light water bottles for seated arm curls once you know the movement suits you.

### Common mistakes

- Doing only arm exercises misses major muscles, so include suitable work for your legs, hips, back, abdomen, chest and shoulders.
- Rushing repetitions makes control harder, so start slowly and increase difficulty gradually.

### A structured start

**Start strength work with control**

1. Stage 1: Choose suitable exercises and stable supports; ask a physiotherapist about pain, injury or movement limitations.
2. Stage 2: Learn the technique with a manageable amount of effort and rest when you need to.
3. Stage 3: Establish two sessions each week covering the major muscle groups.
4. Stage 4: Increase repetitions or resistance gradually when you can keep good control.
