Why our bodies expect long walks and endurance effort, and what the numbers say about how far we are from the lives that shaped us
Humans are built differently from other primates. We are the planet’s best endurance runners. That skill helped our ancestors hunt, scavenge, travel, and carry resources across open landscapes. Over tens of thousands of years, those movement demands shaped our bones, tendons, sweat system, and brain.
Today, most of us sit for a long time, eat ultra-processed food and move far less than the people who shaped our species. That gap between the environment we evolved for and the world we now live in is called evolutionary mismatch. This mismatch helps explain rising rates of obesity type 2 diabetes, cardiovascular disease, poor sleep, low mood and faster cognitive decline.
Below, I show the numbers that matter, explain why long walks and endurance effort are not optional and give clear, practical ways to reconnect your daily life with how we evolved to move.
Why running and walking mattered to our ancestors
Two big points explain why we are special as long-distance movers. First, our bodies have unique features among primates that aid endurance running. Long legs, elastic Achilles tendons and a compact torso make running efficient. We also cool with sweat, which lets us work in heat while many quadrupeds must rest. These traits are not accidental. They match a lifestyle that included long walks prowling for food and endurance hunts that could cover many kilometers. The classic review that framed this idea makes the case that endurance running played a central role in human evolution.
Second, many prehistoric and ethnographic accounts show humans used walking and running as tools for survival. Persistence hunting and long day ranges in hunter-gatherer groups required covering tens of kilometers across a day or during a hunt. When prey could outrun a human in a sprint, the human advantage was to keep going until the animal overheated or tired. Those activities shaped not only muscles and tendons but also hormonal responses, energy systems and social organization.
The numbers that reveal the gap
How much do hunter-gatherers move?
Field measurements in contemporary forager groups provide a useful window into ancestral activity. For example, data collected from the Hadza show average daily walking distances of about 11 kilometres for men and near 6 kilometres for women. Other recordings of persistence hunts document single hunts of 17 to 35 kilometers in distance, depending on terrain and conditions. Subsistence groups like the Tsimane show high cardiorespiratory fitness across the life course and very low rates of cardiometabolic disease compared with industrialized populations.
How much do modern people move?
By contrast, many adults in industrialized countries average roughly 4 to 6 thousand steps each day, which translates to about 3 to 5 kilometres. National samples often show that a large portion of adults do not meet minimum activity guidelines and that sedentary time frequently exceeds six to eight hours per day. Taken together, these numbers indicate a daily movement gap on the order of several kilometres between typical modern adults and forager populations that still rely on walking and running as part of daily life.
What walking and steps mean for health
Large meta-analyses and prospective studies link step volume and walking time with lower mortality and reduced risk of chronic disease. The association shows consistent benefits with each additional thousand steps per day up to a point, and clear reductions in all-cause mortality and in cognitive decline for people who walk more. Recent reviews on walking for healthy aging highlight improvements in cardiovascular health, cognition, sleep and mood from regular walking. In short, walking is not a waste of time even for young people. It builds resilience and protects the body and brain as we age.
Why battling our nature makes us sick
Our reward and stress systems evolved to favour movement and social cooperation, and high reward from rare calorie-rich food. Modern life flips the script. Ultra-processed food activates reward circuits with little effort. Screens deliver instant stimulation without physical cost. Transport and convenience strip away the daily movement that used to be mandatory. Trying to fight those forces only with willpower commonly fails because the environment still pushes toward the cheap rewards.
The smarter play is to reshape the environment and the day so that activity and effort are MANDATORY.
Practical, evidence-based ways to reconnect with our movement heritage
1 Build daily long walks into your life
Aim for volumes that move you well above typical modern baselines. If your current average is 3 to 4 kilometres per day, work up toward 7 to 10 kilometres spread across the day. Long walks are not only good for the heart, they help glucose regulation, mood and cognitive performance. Walking outdoors also restores circadian cues, which support sleep and appetite.
2 Add purposeful endurance efforts
Include 1 to 3 sessions per week that push your heart rate in moderate to vigorous zones. These sessions can be hill walks, sustained jogs, cycling or loaded carries. Think in minutes per week. A target of roughly 150 minutes of moderate effort or 75 minutes of vigorous effort is a meaningful starting point for most adults.
3 Embrace mixed intensity and varied terrain
Hunter-gatherer movement is rarely uniform. Combine steady walking with short, harder bursts. Include uphill segments, loaded walks and uneven ground. These stimuli build joint resilience, tendon elasticity and cardiovascular fitness more than flat treadmill miles alone.
4 Make movement social and purposeful
People evolved by moving and working together. Join a walking group, recreational team or volunteer for tasks that require carrying or moving. Social effort increases adherence and adds the emotional benefits that solitary exercise can miss.
5 Design your environment for unavoidable movement
Place common objects out of reach from your desk, take phone calls while walking, choose a bus stop one stop earlier or park farther away. Small design nudges add light to moderate movement minutes that accumulate into meaningful weekly volume without needing extra free time.
So what can I do?
Now that you understand how your body was built to move and why modern sedentary habits are creating a health gap, it is time to take action. Start by building long walks into your day, experiment with purposeful endurance efforts, and explore varied terrain and mixed intensity movement.
Track your steps, challenge yourself to increase daily distance, and make activity a social and meaningful part of your life. If you want guidance on creating a practical plan that reconnects your movement habits with how humans evolved, reach out today for a personalized program and start moving like you were built to. Your body and mind will thank you for every step.
