Introduction

You’ve probably heard that adults should aim for at least 150 minutes of physical activity each week.

But have you ever wondered where that recommendation comes from?

The answer is the World Health Organization (WHO).

The WHO develops evidence-based health recommendations by reviewing large bodies of scientific research from around the world. Its Physical Activity Guidelines provide practical recommendations to help people improve their health through regular movement.

Rather than encouraging extreme exercise programmes, these guidelines focus on achievable levels of physical activity that most adults can incorporate into their daily lives.

At 1% Movement, we believe that understanding why these recommendations exist is just as important as knowing the numbers themselves. When people understand the reasoning behind the guidelines, they’re often more confident about building sustainable exercise habits.

In this article, we’ll explain the WHO Physical Activity Guidelines in simple terms, what they mean for everyday life and how you can use them to become more active.

If you haven’t already, we recommend reading How Much Exercise Do Adults Need? first.

What Is the World Health Organization (WHO)?

The World Health Organization (WHO) is a specialised agency of the United Nations responsible for promoting global health.

Among its many responsibilities, the WHO reviews scientific evidence and develops health recommendations used by governments, healthcare professionals and public health organisations around the world.

Its Physical Activity Guidelines are based on decades of research examining how regular movement influences health across different populations.

These recommendations are designed to help people live healthier, more active lives.

Why Did the WHO Develop Physical Activity Guidelines?

Modern lifestyles have changed dramatically.

Many adults now spend much of their day:

• Sitting at desks. 
• Working on computers. 
• Driving.
• Watching television. 
• Using smartphones and tablets. 

As daily movement has decreased, physical inactivity has become an important public health concern.

The WHO developed its physical activity recommendations to encourage people to:

• Move more. 
• Sit less. 
• Improve overall health. 
• Reduce the risk of many chronic diseases. 
• Maintain physical function throughout life. 

Rather than focusing on athletic performance, the guidelines are designed to promote lifelong health.

Who Are These Guidelines For?

The WHO provides physical activity recommendations for different population groups, including:

• Children and adolescents. 
• Adults.
• Older adults. 
• Pregnant and postpartum women. 
• People living with chronic conditions. 
• People living with disabilities. 

This article focuses on the recommendations for healthy adults aged 18 to 64 years.

Although the specific recommendations vary slightly between groups, the overall message remains consistent:

Move more and sit less.

The Core Recommendations

For most adults, the WHO recommends aiming for either:

• 150–300 minutes of moderate-intensity physical activity each week, or 
• 75–150 minutes of vigorous-intensity physical activity each week, or 
• An equivalent combination of both.

Adults are also encouraged to perform muscle-strengthening activities involving the major muscle groups on at least two days each week.

These recommendations provide a practical target rather than a strict rule.

Any increase in physical activity is beneficial, particularly for people who are currently inactive.

Why 150 Minutes?

Many people wonder why the recommendation is specifically 150 minutes.

This number wasn’t chosen randomly.

It reflects scientific evidence showing that around this level of moderate-intensity physical activity is associated with meaningful health benefits for most adults.

Importantly, this doesn’t mean benefits only begin at 150 minutes.

Research consistently shows that some physical activity is better than none, and additional health benefits may be gained by becoming more active.

Think of 150 minutes as a practical minimum target—not an all-or-nothing requirement.

It’s About Weekly Activity, Not Daily Exercise

One common misunderstanding is that adults need to exercise every day.

In reality, the WHO recommendations refer to total weekly physical activity.

For example, 150 minutes could be achieved by:

• 30 minutes on five days each week. 
• 50 minutes on three days. 
• Several shorter sessions spread throughout the week. 

There isn’t one perfect schedule.

The best routine is the one that fits your lifestyle and allows you to stay consistent.

Muscle-Strengthening Is Part of the Guidelines

Aerobic activity is only one component of the recommendations.

Adults should also include muscle-strengthening activities involving the major muscle groups on at least two days each week.

Examples include:

• Bodyweight exercises. 
• Resistance bands. 
• Free weights. 
• Weight machines. 
• Pilates (depending on the exercises performed). 

Maintaining muscle strength supports:

• Everyday function. 
• Bone health. 
• Balance.
• Mobility.
• Healthy ageing. 

Strength training complements aerobic activity and contributes to overall physical health.

Reducing Sedentary Behaviour Is Also Part of the Guidelines

The WHO Physical Activity Guidelines don’t only encourage people to be physically active—they also recommend reducing sedentary behaviour.

Sedentary behaviour refers to activities that involve very little movement while sitting, reclining or lying down during waking hours.

Common examples include:

• Working at a computer. 
• Watching television. 
• Driving.
• Studying.
• Using a smartphone or tablet for extended periods. 

Spending long periods sitting has become increasingly common in modern life.

Although many jobs require sitting, regularly breaking up sedentary time with movement is encouraged.

Simple ways to reduce prolonged sitting include:

• Standing up every 30–60 minutes. 
• Walking while talking on the phone. 
• Stretching during work breaks. 
• Taking a short walk during lunch. 
• Choosing the stairs instead of the lift. 

These small movement breaks can complement your regular exercise routine and help you accumulate more physical activity throughout the day.

Applying the WHO Guidelines in Everyday Life

The WHO recommendations are designed to be flexible.

You don’t have to complete all your physical activity in a gym or follow a complicated exercise programme.

Instead, think about how movement can naturally fit into your lifestyle.

For example:

At Home

• Do household chores. 
• Garden.
• Follow a home workout. 
• Play actively with your children. 

At Work

• Walk during breaks. 
• Stand during phone calls. 
• Stretch every hour. 
• Walk to a colleague instead of sending a message. 

During Leisure Time

• Go for a brisk walk. 
• Ride a bicycle. 
• Swim. 
• Dance.
• Join a recreational sports club. 

The goal isn’t to find the perfect exercise programme—it’s to build a routine that you enjoy and can maintain consistently.

The Guidelines Are a Target, Not a Test

Some people become discouraged if they don’t immediately achieve 150 minutes of physical activity each week.

However, the WHO recommendations should be viewed as a goal to work towards, not a pass-or-fail test.

If you’re currently inactive, increasing your activity from zero to even a small amount is a positive step.

For example:

• A 10-minute walk is better than no walk. 
• One strength training session is better than none. 
• Taking the stairs occasionally is better than always using the lift. 

As your confidence and fitness improve, you can gradually increase your activity level.

Progress matters far more than perfection.

Common Misconceptions

“I Must Exercise Every Day”

No.

The recommendations refer to total weekly physical activity, not daily exercise.

Many people spread their activity across several days, while others prefer shorter sessions more frequently.

Choose a routine that suits your schedule.

“Only Vigorous Exercise Counts”

Not true.

Moderate-intensity activities such as brisk walking also contribute towards the recommendations.

You don’t have to perform high-intensity workouts to improve your health.

“If I Miss One Week, I’ve Failed”

Everyone has busy weeks.

Illness, work commitments or family responsibilities may temporarily interrupt your routine.

Rather than giving up, simply return to your normal activity when you’re able.

Healthy living is built over months and years—not a single week.

“The Guidelines Are Only for Athletes”

Not at all.

The WHO Physical Activity Guidelines were developed for the general population.

They’re designed to help everyday people become healthier, regardless of their current fitness level.

Frequently Asked Questions

Are the WHO Physical Activity Guidelines mandatory?

No.

They are evidence-based recommendations developed to help people improve their health.

They provide practical targets rather than strict rules.

What if I can’t reach 150 minutes each week?

Start with whatever amount of physical activity feels manageable.

Any increase in movement is beneficial compared with remaining inactive.

Gradually increase your activity as your fitness improves.

Can I combine moderate- and vigorous-intensity activities?

Yes.

The WHO recommendations allow adults to accumulate an equivalent combination of moderate- and vigorous-intensity physical activity throughout the week.

Why is strength training included?

Strength training helps maintain muscle mass, bone health, balance and physical function.

These benefits become increasingly important as we age.

That’s why the WHO recommends muscle-strengthening activities on at least two days each week.

Do I need special equipment?

No.

Many activities require little or no equipment.

Walking, climbing stairs, bodyweight exercises and home workouts are all effective ways to become more physically active.

Conclusion

The WHO Physical Activity Guidelines provide a simple, evidence-based framework for helping adults become more active and improve their long-term health.

Rather than encouraging extreme exercise programmes, the guidelines emphasise regular movement, strength training and reducing prolonged sitting. They recognise that every person starts from a different place and that even small increases in physical activity can make a meaningful difference.

Remember, these recommendations are not about achieving perfection.

They’re about encouraging more movement, less sitting and building habits that you can maintain throughout life.
