As the old saying goes, "A tendon is one inch long and its life will be extended by ten years". Yijinjing also records the discussion about tendons and health: "Weak tendons are slack, strong tendons are strong, and harmonious tendons are healthy." Whether it is the traditional fitness exercise in China, Yijinjing, Wuqinxi, Baduanjin, Tai Ji Chuan, or modern gymnastics, aerobics and yoga, it attaches great importance to lacing.

In Huangdi Neijing, a classic of traditional Chinese medicine, tendons do not appear independently. Where tendons are mentioned, a word named "Meridian" is added in front of it. The so-called meridian tendons refer to the direction of tendons in the human body, most of which are vertically distributed.

In Huangdi Neijing, it is said that bones are strong and tendons are soft, qi and blood are smooth, acupoints are encrypted and bones are refined. Skeleton and muscles should be symmetrical, and when they are asymmetrical, the body will have problems. Therefore, once the muscles of the human body are tense and cramped, it will have an impact on people's health and produce uncomfortable symptoms.

Extended data:

Support can effectively prevent muscle strain. The correct lacing method can make the body's blood smooth and achieve the purpose of self-healing and self-diagnosis. From the perspective of traditional Chinese medicine, the circulation of tendons and blood is complementary, and tendons are often stretched, and the internal organs will also stretch tendons, thus prolonging life.

According to the Taoist theory of health preservation, the direction of the twelve meridians is the same as that of the twelve collaterals, so the tendons at the contraction are also different, and it hurts if it fails. Lacing tendons can soften stiff tendons, reduce dislocation on the spine, and relieve and eliminate pain, numbness and swelling in waist, knees, limbs and all parts of the body.

Special attention should be paid to stretching tendons. Personal will can't eliminate muscle strain, especially pay attention to gradual progress and avoid impatience.
