Do Teens Need 60 Minutes of Exercise Every Day? What WHO’s 14% Means
Short answer: WHO estimated that 14% of adolescents aged 11–17 were active for at least 60 minutes on all seven days of the previous week in 2025. That does not mean the other 86% did no exercise. A teenager who reached 60 minutes on six days—or moved for shorter periods every day—would still fall outside the seven-day group.
- Released and published online: November 4, 2026
- Scope: Global, regional, and country estimates for ages 11–17 across 140 countries and territories
- Evidence base: 389 population-based surveys involving more than 3.2 million adolescents
- Measure: Self-reported number of days in the past week with at least 60 total minutes of moderate-to-vigorous physical activity
What does WHO’s 14% figure measure?
An “active day” meant accumulating at least 60 minutes of moderate-to-vigorous activity, including movement through play, sport, physical education, walking, cycling, or other settings. The 2025 global estimate found that 14% reported seven active days, while the average was 2.7 active days per week.
The indicator places someone with six 60-minute days and someone with shorter daily activity outside the seven-day category. It therefore cannot be translated into “86% did no physical activity.”
Does “one in four had zero active days” mean no movement at all?
About 25%—roughly 240 million adolescents—reported zero days meeting the 60-minute threshold during the previous week. That does not establish that they did no walking, play, or activity lasting less than an hour. The survey counted threshold days, not every minute of movement.
Likewise, reporting seven active days does not by itself show that muscle- and bone-strengthening activity, sedentary time, sleep, or intensity patterns were all optimal.
How large was the sex gap?
Zero active days were estimated for 28% of girls and 22% of boys. Seven active days were reported by 11% of girls and 17% of boys. The study found that girls were less active in almost every country and WHO region.
WHO does not frame this only as an individual motivation problem. Safe walking and cycling routes, school opportunities, cost, access to public space, social norms, and care responsibilities can shape whether activity is practical and safe.
Has adolescent activity improved since 2010?
Global adolescent activity changed little between 2010 and 2025. WHO concluded that no country is currently on track to achieve the global target of a 15% relative reduction in physical inactivity by 2030 from the 2010 baseline.
This is a population surveillance result, not a test that calculates an individual teenager’s future health risk. Its main purpose is to compare patterns and monitor policy progress.
Can the global average be applied to one country or one teenager?
No. Although the analysis covered 140 countries and territories, a global estimate of 14% or 25% is not an individual probability and should not be substituted for a current national survey. Survey years, sampling, school attendance, transport, culture, and local environments vary. Country estimates also combine observed survey data with statistical modelling.
WHO guidance counts activity accumulated across the day and emphasizes that some activity is better than none. The report is not an instruction for every teenager to begin a sudden intensive program. Adolescents with pain, disability, or heart or breathing conditions may need an individualized plan.
Important limitations
- Most activity was self-reported, making recall and social-desirability bias possible.
- Many source surveys were school based and may underrepresent adolescents who are not in school.
- Bayesian hierarchical models estimated missing country-year patterns and borrowed information across regional structures.
- Counting 60-minute days does not capture all shorter activity, exact intensity, strengthening exercise, or sedentary time.
- These surveillance data cannot establish the individual causes of inactivity or prove that a specific policy produced a change.
