Please hold your stomach and chest up on the treadmill

Some people have the habit of hunching their backs while running, which causes the center of gravity to tilt forward. This will increase the pressure on the lumbar spine and cause lumbar strain over time.

In addition, the shock of falling when running brings an impact force to the soles of the feet that is about 5 times the body weight. The forward tilt of the center of gravity will bring greater impact force to the leg and foot joints, which will cause discomfort over time. Therefore, when exercising on a treadmill, you must tighten your abdomen, chest, and waist and back muscles.

Incorrect arm swinging can also cause physical discomfort. Do not swing your arms left and right, as this will cause your center of gravity to swing left and right, which will have an adverse effect on your knee joints. Swing your arms back and forth when exercising on a treadmill.

If someone makes a very loud noise when running, it is most likely because they land directly on the soles of their feet.

When the soles of your feet land directly on the ground, the reaction force of the ground on the human body will be transmitted to the spine and brain through the bones. This is why some people feel uncomfortable in their head after exercising on a treadmill. You should follow an arc-shaped transition from the heel to the sole of the foot and land as gently as possible.

In addition, you should also pay attention to breathing adjustment and timely hydration. It is best to exhale after three steps and inhale after three steps. When exercising, you should drink some 10-16 degree boiled water, purified water or electrolyte drinks, which is good for heart health.
