Experts point out that running involves the nervous, muscular, skeletal, and cardiovascular systems. Incorrect posture may actually increase fatigue and even lead to injury. Here are their suggestions:

1. Don't look down; keep your head up and eyes focused ahead to avoid straining your cervical spine.
2. When running uphill, take shorter steps to make it easier.
3. Land your feet lightly and quickly; heavy foot strikes increase the load on your bones. Your knees should be slightly bent when your feet touch the ground.
4. Keep your back straight and relaxed. Leaning forward often indicates poor stability; try to stay upright to engage your muscles more effectively.
5. Avoid excessive side-to-side twisting of your hips and waist, as this increases the risk of injury.
6. Bend your arms at about 90 degrees and swing them vigorously while running.
7. Keep your hands naturally relaxed while running. Don't clench your fists too tightly—your hands can also be open with palms facing inward.
8. Keep your shoulders relaxed. Otherwise, you may hunch over, get more fatigued, and experience stiff neck.
9. Choose a running plan that suits you.
