2.1.3 Adults 18–64 Years
These recommendations apply to all healthy adults aged 18–64, irrespective of gender, race, ethnicity or socio-economic status. Adults and youth with disabilities may follow them with adjustments to suit their capacity or limitations, and any adult with a medical condition should follow the advice of a medical official. As with younger age groups, activity should be built up progressively — beginning with simple exercises and moving to complex ones, gradually increasing frequency, duration and intensity.
| Aspect | Recommendation |
|---|---|
| Intensity | Moderate to vigorous. |
| Types of Activities | Muscular strengthening (strength) and aerobic physical activities. |
| Aerobic activities | 150 to 300 minutes per week at moderate intensity, or 75 to 150 minutes per week at vigorous intensity; one aerobic activity bout should be at least 10 minutes. |
| Muscle strengthening activities | Activities involving the major muscles, on two or more days in a week. |
| Benefits | Regular physical activity helps lower the risk of all causes of mortality (for example heart disease, high blood pressure, stroke, Type 2 diabetes, metabolic syndrome, colon and breast cancers, and depression) and of hip or vertebral fractures. It develops a higher level of cardiorespiratory and muscular fitness and helps maintain a healthy weight with healthy body composition and bone health. It also lowers the risk of Non-Communicable Diseases and depression. |
| Activities | Physical activities (walking, jogging, swimming, weight training, dancing, etc.), occupational work, household work (car washing, gardening, etc.), games, sports, recreation, transportation (walking, cycling), and planned exercises done with or within the family and community. |
Why This Age Band Needs Its Own Guideline
Adulthood (18–64) is the longest single stretch covered by the WHO recommendations, and it is also the window in which lifestyle-disease risk accumulates fastest. Unlike school-age children, most adults no longer get incidental activity from compulsory physical education or play — work becomes desk-bound, commuting replaces walking, and screens fill leisure time. The guideline exists precisely to counter this: it is written as a minimum floor, not an ideal ceiling, so that an adult with a sedentary job can still protect the heart, lungs, bones and metabolism from the slow damage of inactivity. This is also the stage at which early habits either consolidate into a lifelong pattern or are lost for good, which is why the benefits column names so many specific, serious conditions rather than a vague "stay healthy" claim.
Turning the Target Into a Weekly Routine
The 150–300 minute moderate-intensity target is designed to be flexible. WHO treats roughly one minute of vigorous activity as equivalent to about two minutes of moderate activity, so an adult who prefers intensity over duration can mix the two — for example, three 30-minute brisk walks (moderate) plus two 20-minute runs or sport sessions (vigorous) in a week comfortably clears the floor, and adding a short bodyweight-exercise circuit on two of those days also satisfies the muscle-strengthening requirement. Breaking the weekly total into sessions of at least 10 minutes each, rather than one long weekend burst, spreads the cardiovascular and metabolic benefit across the week instead of concentrating strain on one or two days.
