Walking is a common form of locomotion in which a person or animal moves forward using its legs in a sequence of steps. Unlike faster gaits, walking is defined by having at least one foot in contact with the ground at all times; it is generally slower and less forceful than running. People walk for travel, work, exercise, socializing and ritual activities, and walking remains the most widespread human movement worldwide.

Characteristics and biomechanics

The cycle of walking is typically divided into two phases: the stance phase, when a foot bears weight on the ground, and the swing phase, when the foot moves forward. Human walking usually features alternating periods of single-leg support and brief double support, but it lacks a flight phase when both feet are off the ground. Efficient walking depends on coordinated muscle activity, joint motion in the hips, knees and ankles, and balance controlled by the nervous system.

  • Gait cycle: repeated sequence of heel strike, mid-stance and toe-off for each leg.
  • Energy use: walking is energy efficient at low speeds compared with running.
  • Variations: strolling, brisk walking, power walking and marching differ by speed and posture.

History and development

Bipedal walking is a defining trait of humans and evolved in early hominins over millions of years, freeing the hands for tool use and carrying. Across cultures, walking has also shaped settlement patterns, trade routes and religious practices — from everyday commutes to long-distance pilgrimages and exploratory travel.

Health, fitness and practical uses

Walking is widely recommended as accessible aerobic activity. Regular brisk walking supports cardiovascular health, weight management, bone and joint function, and mental wellbeing. It is low-impact compared with higher-intensity sports, making it suitable for many ages and fitness levels. People use walking for transportation, recreation (hiking, nature walks), therapy and as part of workplace or urban design promoting active travel.

  • Benefits: improved circulation, glucose control, mood and mobility.
  • Practical tools: pedometers and walking groups encourage consistency.

Technique, safety and distinctions

Good walking technique emphasizes an upright posture, relaxed shoulders, natural arm swing and steady steps. Appropriate footwear and gradual progression help prevent injury. Distinct from running, walking maintains ground contact with one or both feet and typically produces lower impact forces. Different animals show diverse walking patterns — for example, quadrupeds use alternating limb pairs while many birds walk in short, rapid steps.

Whether used for short errands or long treks, walking remains a fundamental, low-cost activity that supports daily life, public health and cultural tradition.
