How much should children move each day? The World Health Organization recommends that 5- to 17-year-olds get at least 60 minutes a day of moderate-to-vigorous physical activity, with activities that strengthen muscle and bone at least 3 times a week. Under-5s have their own guideline built around 180 minutes a day, which also covers screen time and sleep. We set out the WHO material as published.
1. Ages 5–17: 60 minutes every day. At least 60 minutes of moderate-to-vigorous activity daily, and muscle- and bone-strengthening activity at least 3 times a week.
2. Ages 1–4: 180 minutes a day. For 3–4-year-olds, at least 60 of those minutes should be moderate to vigorous. Do not keep them restrained for more than an hour at a time; screen time for 2–4-year-olds is no more than 1 hour.
3. Most adolescents fall short. WHO reports 81% of 11–17-year-olds are insufficiently active (girls 85%, boys 78%).
Ages 5–17 — WHO recommendations
- At least 60 minutes of moderate-to-vigorous physical activity daily.
- Muscle- and bone-strengthening activities at least 3 times a week.
Sixty minutes a day is 420 minutes a week, about 2.8 times the adult recommendation of 150 minutes of moderate activity (our arithmetic). That is why “150 minutes a week is enough” does not carry over to children. To judge intensity, see our talk test on exercise intensity.
Under 5 — the 24-hour guideline (2019)
| Age | Activity · restraint · screens | Sleep |
|---|---|---|
| Under 1 | Active several times a day in varied ways, at least 30 minutes in prone position · not restrained for more than 1 hour at a time · screen time not recommended | 0–3 months 14–17 hours, 4–11 months 12–16 hours |
| 1–2 | At least 180 minutes of varied activity · not restrained for more than 1 hour · no screens at 1, no more than 1 hour at 2 | 11–14 hours |
| 3–4 | At least 180 minutes, of which at least 60 moderate to vigorous · screens no more than 1 hour (less is better) | 10–13 hours |
Taken from WHO’s under-5 guidelines announced on 24 April 2019.
How far short — WHO statistics
The WHO physical activity fact sheet (26 June 2024) says 80% of adolescents do not meet the recommended levels; for 11–17-year-olds, 81% are insufficiently active, with girls (85%) less active than boys (78%). These are global figures, not Korea-specific.
Splitting 60 minutes — our example
| When | Example | Minutes |
|---|---|---|
| Getting to and from school | Brisk walking · cycling | 20 |
| Breaks · PE | Running games · ball games | 20 |
| After school | Skipping · playground · sports club | 20 |
| Total | 60 | |
The layout is our example. WHO sets the amount, 60 minutes a day, not how to split it. Adding play that loads muscle and bone, such as hanging, jumping or skipping, three times a week meets the second recommendation too.
Checklist
- ☐ Ages 5–17 — 60 minutes of getting out of breath today?
- ☐ Muscle and bone strengthening 3 times a week (jumping, hanging)
- ☐ Ages 1–4 — 180 minutes a day; no more than an hour at a time in a buggy or seat
- ☐ Screens no more than 1 hour at 2–4, none under 1
- ☐ Age-appropriate sleep
Questions that remain
After-school classes leave no time for 60 minutes.
The WHO material we quote sets the amount, 60 minutes daily, without saying whether it may be split. Counting short bouts such as a brisk walk to school, if at least moderate, is our interpretation.
What about Korean children?
This article covers WHO’s global data only. We did not check Korean adolescent activity statistics this time.
