Some people are used to running with their chests out. When the body's center of gravity leans forward, it will increase the pressure on the lumbar spine and cause lumbar strain for a long time. In addition, when running to the ground, the impact force of the impact is almost five times of the weight. If the center of gravity leans forward, it will bring greater impact to the joints of legs and feet, which will cause discomfort over time. Therefore, when you exercise on the treadmill, you must tuck in your abdomen and chest and tighten your back muscles.

Incorrect swing arm can also cause discomfort. Don't swing your arms left and right, which will cause the center of gravity to swing left and right, which will adversely affect the knee joint. When exercising on the treadmill, swing your arms back and forth.

Some people make a particularly loud noise when running, probably landing directly on the ground with their soles. Touching the sole of the foot directly will transmit the reaction force transmitted from the ground to the human body to the spine and brain through the bones, which is also the reason why some people feel uncomfortable after exercising on the treadmill. You should follow the arc transition landing method from heel to sole, and try to land gently.
