Regular activity supports your heart, blood sugar and ability to keep doing everyday things.

**The number:** Insufficiently active adults have a 20% to 30% higher risk of death ([WHO, 2024](https://www.who.int/news-room/fact-sheets/detail/physical-activity))

## The evidence

- Evidence grade: A. Grade A: meta-analyses of randomised trials, or a major guideline consensus.
- Basis: WHO 2020 guideline consensus, with WHO's pooled estimate of risk in insufficiently active adults
- Impact: 94/100. The impact score is an editorial prioritization heuristic for the general list, not a validated estimate of your personal risk.

## Why it matters

Activity that raises your breathing rate improves heart and lung function and helps prevent cardiovascular disease and diabetes. WHO reports that people who are insufficiently active have a 20% to 30% higher risk of death than people who are sufficiently active. The guideline is 150 to 300 minutes of moderate activity each week, or an equivalent amount of vigorous activity, and some activity is useful even before you reach that range.

## How to do it

1. Choose an activity you can repeat, such as brisk walking, cycling or swimming.
2. Start with a manageable session and gradually add time across the week.
3. At a moderate pace you can talk, but singing is difficult.
4. Put sessions in your calendar and count active travel toward your total.
5. Plan sessions on the days you can reliably protect and work toward the weekly total rather than a perfect daily streak.

## Talk to a clinician first

If a health condition limits activity, ask a clinician which type and amount suits you.

## Putting it into practice

### Start now

- 1 minute: Pick a time tomorrow for a short brisk walk and write it in your calendar.
- 5 minutes: Take an easy five minute movement break using an activity you already tolerate, such as walking or seated movement; stop for pain or feeling unwell.
- 15 minutes: Spend five minutes choosing an enjoyable activity and ten minutes finding three realistic places for it in your week; ask about adaptations if a condition limits you.
- 30 minutes: Take a brisk walk of up to 30 minutes at a pace where you can talk but not sing; shorten it or split it if you need to.

### What it looks like

- Add a short walk to your lunch break, at a pace that suits your current ability.
- If you prefer swimming or cycling, use that as your regular activity instead.

### Common mistakes

- Starting too hard can make the next session daunting, so begin with a manageable amount and build gradually.
- Waiting for a free half hour can mean doing nothing, so use shorter sessions when they fit.

### A structured start

**Build an activity week you can repeat**

1. Stage 1: Choose an activity you enjoy and can do comfortably; get advice on adaptations if needed.
2. Stage 2: Repeat a short, manageable session on days that fit your routine.
3. Stage 3: Add time gradually; at moderate effort you can talk but would struggle to sing.
4. Stage 4: Work toward 150 minutes of moderate activity a week, in chunks that suit you, without treating the target as a pass or fail test.
