① Promote the blood circulation of upper limbs, and exercise the whole body skeletal muscle and its coordination;

(2) When crawling, the head is lower than usual, and blood is easy to flow to the heart, brain and upper limbs, which can increase the blood supply to these parts;

(3) When crawling, all limbs touch the ground, and the whole body weight is dispersed to all limbs, which can reduce the load of all parts of the body, especially the lumbar spine;

(4) Crawling means that all muscles, ligaments, bones and nervous system of the whole body should participate in sports, which can make muscles more tense and elastic, and exercise respiratory function and systemic coordination.

Because the crawling posture is different from the usual walking posture, I haven't adapted at first, and I may fall down because of my uncoordinated body. In addition, blood pours into the brain and heart when crawling, and people with high blood pressure, heart disease and cerebrovascular disease are not suitable for crawling.
