Have you ever wondered if you are running the right way?

1) Your eyes should be focused on the ground about 10 to 20 feet ahead of you. Don't stare at your feet. Not only is this proper running form, but it's also a safer way to run because you can see what's coming and avoid falling.
2) Try to keep your hands at waist level, right about where they might lightly brush your hip. Your arms should be bent at a 90-degree angle. Some beginners have a tendency to hold their hands way up by their chest, especially as they get tired. 
3) As you run, keep your arms and hands as relaxed as possible. Avoid tightening your hands into fists. If you're clenching your hands, the tension will move from there up your arms to your shoulders and neck.
4) Keep your posture straight and erect. Your head should be up, your back straight, and shoulders level. Keep your shoulders under your ears and maintain a neutral pelvis. Make sure you're not leaning forward or back at your waist, which some runners do as they get fatigued.
5) Your shoulders should be relaxed and square or facing forward, not hunched over. Rounding the shoulders too far forward tends to tighten the chest and restrict breathing. You'll breathe a lot easier if your shoulders are relaxed.
6) Avoid side-to-side arm swinging. If your arms cross over your chest, you're more likely to slouch, which means you're not breathing efficiently. Inefficient or shallow breathing can also lead to side stitches or cramps in your abdominal area.
7) Your arms should swing back and forth from your shoulder joint, not your elbow joint. Think of your arm as a pendulum, swinging back and forth at your shoulder. Drive your elbow backward and then let it swing back toward you.
8) If you bounce when you run, known as vertical oscillation, your head and body are moving up and down too much, which wastes a lot of energy. The higher you lift yourself off the ground, the greater the shock you have to absorb when landing and the faster your legs will fatigue.
