1, Baduanjin moves gently and slowly. Moderate and slow exercise can fully relax the living body and give full play to the regulating function of the human body, which is conducive to the overall recovery of the body. The results show that by practicing Baduanjin, the elasticity of human blood vessels is obviously improved, the myocardial contraction is more powerful, the excitability of vagus nerve is further increased, and the fullness and rhythm of blood vessels will be stronger.

2. The combination of tightness and movement is the remarkable feature of Baduanjin. He asked to be loose and tight, loose and unremitting, tight and loose, and gently stretch when practicing. "Tightness" is only a moment in action, while looseness runs through the whole process of action. This close cooperation and frequent change of tightness are helpful to stimulate and adjust the body's coordination ability of Yin and Yang, promote the circulation of menstruation and qi, smooth joints, promote blood circulation and remove blood stasis, and strengthen tendons and bones.

3. The central part of Ba Duan Jin exercise is the spine. The whole set of kungfu exercises requires the center of gravity to change constantly from top to bottom and from left to right, striving for body balance and coherent movements. At the same time, all movements are required to be directed through a center, that is, the spine. The first four potentials of Baduanjin highlight the adduction and strength accumulation of scapula, while the last four potentials focus on the dive, torsion and extension of waist and hip. The strength is gradually transmitted from the back of the trunk to the limbs, and tightened from the inside out. It seems that some resistance must be overcome in the process of exercise, so that the meridians and bones of the limbs can be fully extended.
