What UK guidelines say
The UK Chief Medical Officers’ physical activity guidelines set a weekly benchmark for adults, rather than requiring a particular sport or exercise class. Walking can count towards that benchmark when its pace brings the effort to a moderate level. The right pace depends partly on your fitness, so effort is more useful than a fixed speed. Strengthening activity is also part of the recommendation.
Moderate activity
The 2019 UK Chief Medical Officers’ physical activity guidelines recommend a weekly mix of aerobic and strengthening activity. Moderate intensity raises your breathing and heart rate; as a simple check, you can talk but not sing.
- Aim for at least 150 minutes of moderate-intensity activity each week, which could include walking at a pace that noticeably raises your breathing.
- Alternatively, the weekly aerobic target is at least 75 minutes of vigorous-intensity activity, when breathing becomes much harder and conversation is difficult.
- Do muscle-strengthening activities on at least two days each week, working major muscle groups; these complement rather than replace aerobic activity.
- Any activity is better than none, so shorter bouts can be worthwhile when reaching the full weekly target is not yet realistic.
The aerobic minutes can come from different activities, and walking is one practical option. The aim is a sustainable weekly total, not completing every minute in one session.
Brisk walking
Brisk walking generally counts as moderate-intensity activity. Use the talk test to judge the effort: you should be able to talk, but not sing. Your pace may be slower or faster than someone else’s because fitness levels differ; focus on how your body responds rather than chasing a particular speed. A walk only contributes moderate-intensity minutes while you are moving at that level of effort. An easy stroll may still add movement to your day, but it may not meet the moderate threshold. If brisk walking suits your current ability, regular walks can build towards the weekly target without needing specialist equipment or a gym. For example, fitting a 30-minute brisk walk into five days of an ordinary week provides a straightforward route to 150 minutes.
Daily steps: what the research shows
Step counts provide a simple way to describe everyday movement, but research does not identify one number that suits everyone. Studies have compared daily totals with health outcomes across different age groups. Their findings help put familiar targets into context, including the widely quoted 10,000-step figure. The results are best understood as population-level patterns, not a personal prescription.
The 10,000 steps figure
The 10,000-step figure did not begin as a threshold established by clinical research. It is commonly traced to a Japanese pedometer marketing campaign in 1965, which promoted the Manpo-kei device. The number made a memorable target for a consumer product; it was not selected because researchers had shown that exactly 10,000 steps produced a specific health benefit.
That history does not make step counting useless. It does mean the familiar figure should not be treated as a minimum required for health or as a point below which walking has no value. Research has since examined a range of daily totals and how they relate to outcomes, rather than testing the 10,000-step mark as a universal clinical cutoff.
Newer evidence
Two influential analyses found associations between higher step counts and lower mortality, while showing that the patterns differed by age and did not require 10,000 steps for everyone.
| Study and population | Step-count finding | Where the association levelled off |
|---|---|---|
| Lee and colleagues, JAMA Internal Medicine, 2019: older US women | About 4,400 steps a day was associated with lower mortality than about 2,700 steps a day. | About 7,500 steps a day. |
| Paluch and colleagues, The Lancet Public Health, 2022: adults aged 60 and over | Risk fell as daily steps increased within the studied range. | Roughly 6,000 to 8,000 steps a day. |
| Paluch and colleagues, The Lancet Public Health, 2022: younger adults | Risk fell as daily steps increased within the studied range. | Roughly 8,000 to 10,000 steps a day. |
The 2019 findings apply to the older US women studied, while the 2022 meta-analysis combined results from multiple populations. Both were observational: they show that step counts and mortality were associated, but cannot prove that walking more alone caused the lower risk. Other differences between people may also contribute.
Use a step count as a helpful guide to your own activity, not a fixed target that everyone must reach. A useful goal can vary with age, health and current routine.
How many calories walking burns
The calories used during a walk vary with body weight, walking speed, slope and any load carried. A heavier person generally uses more energy than a lighter person covering the same distance at the same pace. The MET method provides a practical way to estimate energy use from walking speed, body weight and time. Treat the result as a guide rather than an exact measure of an individual walk.
The simple estimate
Estimate calorie expenditure with this equation: calories = MET value x body weight in kg x hours. A MET, or metabolic equivalent of task, represents the energy cost of an activity compared with resting; a higher MET value indicates greater energy use per kilogram for the same duration. For example, enter body weight in kilograms and walking time in hours.
The Compendium of Physical Activities (Ainsworth and colleagues, 2011) lists these approximate MET values for walking at the following speeds:
| Walking speed | MET value |
|---|---|
| About 3 mph | 3.5 METs |
| About 3.5 mph | 4.3 METs |
| About 4 mph | 5.0 METs |
These figures give a useful starting point for comparing pace, but they represent standard activity estimates rather than measurements of your exact energy use. A hill or a carried load can make a walk more demanding than the same pace on level ground.
Worked example
For a 70 kg person walking for one hour at 3.5 METs, the calculation is 3.5 x 70 x 1 = about 245 kcal. The value 3.5 represents the activity intensity, 70 is body weight in kilograms, and 1 is the duration in hours. The result is an estimate, not an exact count: an individual may use more or less energy depending on factors such as pace, terrain and how efficiently they walk. Use the figure to make a rough comparison between walks or to understand how duration and pace affect energy use, rather than treating it as a precise personal total.
Starting and keeping up
A walking routine is easier to maintain when it fits ordinary days rather than requiring a special timetable. Short, familiar outings can help you find a duration and route that feel manageable. Allow room for busy days instead of treating a missed walk as failure. A simple plan can make it easier to return to the habit and build consistency over time.
Building up gradually
An easy start is more likely to fit around work, caring responsibilities and changing weather than a demanding schedule. Use the first week to find a repeatable time and a convenient route.
- Start with 10 to 15 minutes at a comfortable pace on three or four days in the first week; choose a route that ends near home.
- Keep the duration steady until it feels manageable, then add a few minutes each week rather than making a large jump in distance or pace.
- When one continuous outing is hard to fit in, split the time into two shorter walks, such as a morning loop and an evening errand.
- Link walking to an existing cue, such as going out after lunch, and keep your shoes and a light jacket beside the door.
- Choose a familiar, mostly level route with a convenient turning point, so you can shorten the outing if your schedule or energy changes.
- Mark completed walks on a paper calendar or phone, and resume at the next planned time after a missed day instead of trying to catch up.
If a walk feels harder than expected, repeat the same duration for another week rather than forcing an increase. A walking exercise plan becomes sustainable through regular returns, not by making every outing longer.
When to ask a doctor
Seek medical advice before starting a walking routine if you have a diagnosed heart condition or another ongoing health problem that could affect exercise. A clinician who knows your history can discuss a suitable starting duration and any adjustments you may need. Ask for advice before beginning if you have been inactive for a long time, particularly if everyday tasks leave you unusually breathless or exhausted. New symptoms, such as chest discomfort, dizziness or breathlessness that is unusual for you, should be assessed rather than tested during a walk. For severe or sudden symptoms, use urgent local medical services. A gradual routine may suit people returning to activity, while those with health conditions, prolonged inactivity or new symptoms should seek personalised advice before setting their starting point.
