Physical activity includes walking, active travel, play and exercise. The recommendations combine aerobic movement, muscle strengthening and less sedentary time, with different targets by age. This is a reference guide based on WHO documents, not a new medical announcement issued in October.

Beyond the gym
WHO defines physical activity as bodily movement that requires energy expenditure. Movement during travel, daily tasks and leisure also counts. Its guidelines inform public health; they do not prescribe a single activity for everyone.
A weekly reference for adults
For adults aged 18 to 64, the recommendation is to accumulate 150 to 300 minutes of moderate-intensity aerobic activity per week, or 75 to 150 minutes of vigorous-intensity activity, or an equivalent combination. Muscle-strengthening activities involving the major muscle groups should be performed on at least two days per week.
As a simple calculation, five 30-minute periods add up to 150 minutes. That distribution illustrates a volume, not a personalized routine. It also does not mean that every walk automatically reaches moderate intensity: duration, intensity and type of activity are separate considerations.
Some movement is better than none; sedentary time also matters
The guidelines emphasize that some physical activity is better than none and that all age groups should limit sedentary time. Moving more and spending less time sitting are related, but they are not identical measures.
Editorial analysis: a useful record should distinguish physical activity from sedentary hours. Adding up minutes without considering intensity, or assuming one session automatically offsets the rest of the week, can lead to a misleading interpretation of the recommendations.
Targets change with age
For adults aged 65 and over, the guidance also includes varied activity that emphasizes functional balance and strength on at least three days per week. For children and adolescents aged five to 17, the reference is an average of 60 minutes per day of moderate- to vigorous-intensity activity across the week.
How an activity should be adapted depends on individual abilities and circumstances. This article explains general criteria; it does not prescribe exercise for illness, pregnancy or disability, and it does not guarantee particular results.
