Walking is great exercise and can be very beneficial aerobically. Aerobic exercise is defined as brisk physical activity that requires the heart and lungs to work harder to meet the body's increased oxygen demand. In other words, it's moving your body to get your heart and lungs to work a little harder.
In humans, walking is composed of several separate processes: 1  Vaulting over a stiff stance leg. 2  Passive ballistic movement of the swing leg. 3  A short 'push' from the ankle prior to toe-off, propelling the swing leg. 4  Rotation of the hips about the axis of the spine, to increase stride length.
