The idea

Walking may be the most underrated form of exercise. It is free, needs no equipment, suits almost everyone and can be done almost anywhere. Brisk walking counts as moderate-intensity activity, and regular walking is linked with lower risk of heart disease, better mood and healthy ageing.

You may have heard of the goal of 10,000 steps a day. It is widely reported to have started as a marketing slogan for a pedometer in 1960s Japan, rather than from research. Studies since then suggest the benefits of steps rise steadily and then level off — for many adults somewhere between about 6,000 and 10,000 steps a day, depending on age — and that any increase from a low starting point helps.

Walking also has benefits beyond the body: time outdoors, a chance to think or talk, and a break from screens. Walking with others makes it social; walking in green spaces may bring extra benefits for mood.

Why it works

Walking is the easiest way to add movement to almost any life — and it helps both body and mind.

A real example

The situation

After a health scare, Mohammed wants to exercise but finds the gym intimidating.

What happened

He starts with a 15-minute walk after dinner each evening with his wife. Over months he builds up to 40 minutes, and they explore new routes at weekends. His doctor is pleased at his next check-up.

The takeaway

The simplest exercise was the one he could actually keep doing.

Use this when you are…

• you want to start moving more
• you need a mental break
• other exercise feels hard to start

Common mistakes

• Dismissing walking as “not real exercise”.
• Treating 10,000 steps as a strict target.
• Walking only when you have a long stretch of time. Short walks add up.

What the evidence says

Strong evidence: Many good-quality studies, usually including randomised trials and reviews that pool them, point the same way. Guidelines tend to recommend it.

Walking’s health benefits are well documented, and large pooled studies of step counts show benefits rising up to around 6,000–10,000 steps a day depending on age. The 10,000-step figure itself did not come from research.

Where this comes from: Exercise and health research; WHO guidelines on physical activity and sedentary behaviour (2020).

Fields that study this: Exercise science, Public health.
