Experts say the most effective way to walk is the natural way. Keep your head high and your back straight. In fitness walking, it is important to remember that your footsteps should fall almost in a straight line: Bend your arms at the elbow. Let them swing from the shoulder with each step. Walking is good for the health of your body. And a new study provides details about the link between walking and your emotional health. Robert Thayer of California State University asked a group of students to describe their feelings of energy and tension. Then he sent the students on a fast walk for ten minutes. When the students returned, they reported feeling less tired and full of energy.
