Walking is how we move.
We use our legs to go. It is good for our bodies. It helps our minds too. Walking keeps us healthy.

Walking is how we move on land.
Many animals walk using their legs. Even tiny bugs with many legs walk too.
Walking is slower than running. When you walk, one foot stays on the ground. This helps you stay steady. Walking is good for your body. It can help your mind feel better. It can also help you learn. Walking is a great way to stay healthy!
Walking is a way many animals move on land.
Even bugs with many legs can walk.
Walking is different from running. In walking, one foot stays on the ground at all times. This is called double-support. In running, both feet leave the ground for a short time. Scientists also look at how high a person's center of mass moves. This is the middle part of the body. During a walk, the center of mass reaches its highest point in the middle of a step.
Walking is very good for your health. It can help your heart and your mind. It can help you focus and learn. Some studies show that taking many steps a day can help people live longer.
You can even change how you walk. Nordic walking uses special poles. These poles help you use more muscles in your chest and arms. This can make your heart work harder. It can also use more energy than walking alone.
Walking is a way that many animals move across the land.
It is one of the main ways legged animals travel. Most animals walk at a slower speed than they run. Scientists call the way a person walks an inverted pendulum gait. This means the body vaults over a stiff limb with each step. This way of moving works for many creatures. Even tiny arthropods with six or eight legs use walking to move.
There is a clear way to tell walking apart from running. In walking, only one foot leaves the ground at a time. This creates a period called double-support where both feet touch the ground. Running is different because both feet leave the ground during each step. You can also watch the center of mass, which is the middle of the body.
During a walk, this center point reaches its highest height in the middle of a step. In running, the center of mass is at its lowest point during that same moment. This rule works well on level ground.
Walking has been part of life for a very long time. Some scientists think walking began underwater with fish that could breathe air. These fish might have walked on the ocean floor.
This may have led to the many land animals we see today. For humans, walking on two legs was a very important change. Footprints found in Kenya show our ancestors may have walked like us 3 million years ago. Walking on two legs helped our ancestors save a lot of energy. This made it much easier to travel than it was for other primates.
Humans have many special body parts that help us walk well. We have long legs and long Achilles tendons. These parts help us save energy while we move. Our hipbones are also shaped in a way that helps us. Even a small child can walk on their own by 11 months old.
Most people walk at a speed of about 5.0 kilometers per hour at crosswalks. In Japan, the standard walking speed is 80 meters per minute. Champion racewalkers can go much faster over long distances.
Walking is also a wonderful way to stay healthy. It can help your heart, your mood, and your memory.
Walking for 30 to 60 minutes a day can be very good for you. Some studies show that taking more steps can help people live longer. You can even use tools to change your walk. Nordic walking uses special poles to work more muscles in your arms and chest. This can increase the energy you use by up to 46 percent.
Even a light walk after a meal can help your body.
Walking, also known as ambulation, is a primary method of terrestrial locomotion for legged animals. It is a way of moving across land that is typically slower than running or other gaits. Scientists define walking as an "inverted pendulum" gait. In this process, the body vaults over a stiff limb or limbs with every single step. This mechanical pattern applies to many different creatures. Even arthropods with six, eight, or more limbs use this method to move.
There is a mechanical way to distinguish walking from running in humans and other bipeds. In walking, only one foot leaves the ground at any given time. This creates a period of "double-support" where both feet are in contact with the ground. In contrast, running is defined by a phase where both feet leave the ground during each step. You can also identify walking by measuring the height of a person's center of mass. During walking, the center of mass reaches its maximum height at mid-stance. In running, the center of mass is at its minimum height during that same moment.
Walking has deep evolutionary roots that stretch back millions of years. Some scientists theorize that walking among tetrapods began underwater. Air-breathing fish may have "walked" on the ocean floor, potentially leading to land-dwelling life. For example, little skates use their pelvic fins to push off the ocean floor. This neural mechanism may have evolved as early as 420 million years ago. While terrestrial tetrapods likely have a single origin, arthropods evolved walking independently several times. This includes groups like hexapods, crustaceans, and tardigrades.
For human ancestors, bipedal walking was a defining characteristic. Fossil evidence suggests that walking on two legs emerged before other major Hominidae traits. Footprints discovered in Kenya suggest ancestors may have walked like modern humans 3 million years ago. This shift was likely driven by metabolic energy efficiency. Human walking is slightly more efficient than the travel of a quadrupedal mammal of similar size. For instance, chimpanzees expend 150% of the energy required by true quadrupeds. Human locomotion is approximately 75% less costly than the movement of chimpanzees.
Our bodies possess specific anatomical features that make this efficiency possible. Humans have longer legs and short, dorsally oriented ischia, which are parts of the hipbone. These features result in longer hamstring extensor moments to improve energy economy. We also have long Achilles tendons that support efficient bipedal movement. Additionally, humans have long femoral necks. This means our hip muscles require less energy to flex while we move. Even early hominins like Ardipithecus ramidus showed signs of energy-efficient bipedal walking.
Walking provides significant health benefits for the human body and mind. Regular, brisk exercise can improve stamina, energy, and weight control. It can also reduce stress and improve mental functions like memory, concentration, and creativity. For people with diabetes, walking two or more hours a week lowered mortality rates by 39 percent. Studies show that taking 4,500 to 7,500 steps a day may reduce premature deaths. A 2023 study found that just 2,337 steps a day reduces the risk of cardiovascular death. Even a light walk after a meal can help reduce glucose spikes.
People also use different techniques and tools to change how they walk. Nordic walking uses specially designed poles to engage the entire body. This activity stimulates muscles in the chest, arms, and core. It can increase energy consumption by up to 46% compared to walking without poles.
Other variants include snowshoeing, which uses wide footwear to provide "flotation" on snow. There is also scrambling, a slow and careful way to walk up steep mountains using both hands. People even participate in beach walking competitions on non-compact sand.
