"Get more exercise" is advice everyone has heard. But how much is enough, what kind counts, and does it matter if you sit at a desk all day? The World Health Organization (WHO) answers these questions in its global guidelines on physical activity and sedentary behaviour, which remain the main international reference for doctors and health agencies.
The guidelines matter more than ever. New data shows that a large share of adults worldwide still don't move enough, and the numbers haven't improved in over a decade. Here's what the WHO recommends, what the latest research says, and how to turn the guidelines into something that fits your week.
Quick answer: The WHO recommends that adults get 150 to 300 minutes of moderate activity (or 75 to 150 minutes of vigorous activity) each week, plus muscle-strengthening exercise on 2 or more days. Adults 65 and older should also do balance and strength activities on 3 or more days a week. The most important message: every move counts, and doing some activity is better than doing none.

What the WHO Guidelines Recommend
Adults aged 18 to 64
- Aerobic activity: at least 150 to 300 minutes of moderate-intensity activity, or 75 to 150 minutes of vigorous-intensity activity, or a mix of both, spread across the week.
- Muscle strengthening: activities that work all major muscle groups on 2 or more days a week.
- Going further: doing more than 300 minutes of moderate activity (or 150 minutes of vigorous activity) a week can bring additional health benefits.
- Less sitting: limit time spent sitting, and replace it with activity of any intensity, even light movement.
Adults aged 65 and older
Older adults are advised to follow the same aerobic and strength targets. On top of that, the WHO recommends varied activities that focus on balance and strength on 3 or more days a week to improve function and help prevent falls. Examples include tai chi, dancing, standing on one leg while holding a chair, and heel-to-toe walking.
Pregnancy, postpartum, and chronic conditions
The guidelines also include advice for pregnant and postpartum women and for people living with chronic conditions or disabilities. In general, they encourage regular activity for these groups too, adjusted to each person's abilities. If you have a health condition or are pregnant, talk to your doctor about what's right for you.
What Counts as Moderate and Vigorous Activity?
A simple way to judge intensity is the "talk test":
- Moderate intensity: you can talk but not sing. Examples: brisk walking, cycling on flat ground, dancing, gardening, doubles tennis.
- Vigorous intensity: you can only say a few words before needing a breath. Examples: running, fast cycling, swimming laps, singles tennis, hiking uphill.
As a rule of thumb, one minute of vigorous activity counts about the same as two minutes of moderate activity.
What's Changed: "Every Move Counts"
Older advice often suggested that activity only counted if it lasted at least 10 minutes at a time. The current WHO guidelines dropped that requirement. Short bursts, like climbing stairs, walking to the shop, or playing with your kids, all add up. The WHO's message is clear: doing some physical activity is better than doing none, and people who are currently inactive should start small and build up gradually.
The guidelines also put new focus on sedentary behaviour. Long hours of sitting are linked to poorer health, so the WHO recommends breaking up sitting time and, for people who sit a lot, aiming for activity above the minimum targets.
Why This Matters: The Latest Numbers
According to the WHO, about 1.8 billion adults, or 31% of adults worldwide, did not meet the recommended activity levels in 2022. That figure has risen from 26% in 2010, and if the trend continues, it could reach 35% by 2030. Inactivity is higher among women (34%) than men (29%), and people over 60 are less active than younger adults.
A study published in Nature Health in March 2026 found a similar picture. Researchers looked at data from 218 countries between 2004 and 2025. While 92% of countries now have at least one physical activity policy, activity levels among adults have not improved since 2012. In other words, knowing the guidelines isn't enough. What counts is building movement into daily life.
The payoff is worth it. The WHO notes that people who are not active enough have a 20% to 30% higher risk of death than those who are sufficiently active. Regular activity helps lower the risk of heart disease, stroke, type 2 diabetes, several cancers, depression, and dementia, and it supports healthy weight, sleep, and brain health.
How to Meet the Guidelines in a Busy Week
150 minutes sounds like a lot, but it's only about 22 minutes a day. Here are some practical ways to get there:
- Walk briskly for 30 minutes, 5 days a week. You can split it into three 10-minute walks after meals.
- Add two short strength sessions. Squats, push-ups against a wall, lunges, and resistance bands all count.
- Make your commute active. Walk or cycle part of the way, or get off public transport one stop early.
- Break up sitting. Stand up and move for a few minutes every 30 to 60 minutes. Take calls while walking.
- Use weekends. A long hike, a bike ride, or active time with family can cover a big part of your weekly goal.
- Choose activities you enjoy. You're far more likely to keep going if you like what you're doing, whether it's dancing, badminton, or gardening.
A sample week
| Day | Activity | Time |
|---|---|---|
| Monday | Brisk walk | 30 min |
| Tuesday | Bodyweight strength routine | 20 min |
| Wednesday | Cycling or brisk walk | 30 min |
| Thursday | Rest or light stretching | - |
| Friday | Brisk walk + strength | 30 + 20 min |
| Saturday | Hike, dance class, or sport | 45 min |
| Sunday | Relaxed family walk | 20 min |
That adds up to more than 150 minutes of moderate activity and two strength sessions. If this feels like too much right now, start with half and build up over a few weeks. For more ideas on building a routine that sticks, read Building a Healthy Routine That Fits Your Daily Life.
Frequently Asked Questions
Does housework or gardening count?
Yes. If it raises your heart rate and makes you breathe harder, such as vigorous cleaning, mowing, or digging, it counts toward your moderate activity minutes.
Is it okay to do all my activity on the weekend?
Spreading activity across the week is ideal, but research suggests that "weekend warriors" who meet the guidelines in one or two days still gain important health benefits. Any activity is better than none.
I haven't exercised in years. Where should I start?
Start small, even 5 to 10 minutes of walking a day, and slowly increase the time and pace. If you have heart disease, diabetes, joint problems, or other health concerns, check with your doctor before starting something more intense.
The Bottom Line
The WHO guidelines boil down to a simple goal: move more, sit less, and add some strength work. Aim for 150 to 300 minutes of moderate activity a week plus two strength sessions, and include balance training if you're over 65. You don't need a gym or long workouts. Every walk, every flight of stairs, and every break from sitting adds up to better health.
