Correct swing arm posture when running:
1. When running, you should swing your arms in the opposite direction of your legs. In addition, when running, the elbow should be pushed backward, not outward. Be sure to take the shoulder as the fulcrum, keep the arm bent, and push the elbow backward.
2. The bending angle of the arm is about 90 degrees, and the swing amplitude of the elbow joint should be kept within the range of 70 ~ 120 degrees.
Don't stick your fist on your chest or below your hips. In addition, when you put it on, you should use force, arc from your chest to your hips, keep your hands and shoulders relaxed, move smoothly, and don't swing from side to side.
Precautions for running:
1, posture
Running posture should be reasonable. Your upper body should be straight, lean forward slightly, relax your shoulders, bend your elbows naturally, and swing your arms back and forth at your sides. In the process of running, the stride length is not required to be large, but the stride frequency and stride length should be basically the same. Pay attention to the stability of the body's center of gravity, not ups and downs.
Step 2 breathe
Breathing during running is very important. Breathing should have a certain rhythm. When breathing through the nose and mouth at the same time, the mouth does not need to be too wide, and the tongue can be rolled up to prolong the time of air in the mouth and reduce the stimulation of cold air to the respiratory tract. Beginners can suck in two steps and shout in three. Pay attention to exhaling gas from the lungs as much as possible every breath to increase the effective ventilation.
