First of all, this place is quiet. In spring, summer and autumn, it is best to be in the courtyard, corridor, park, forest, river, open field and other places with fresh air and quiet, and it is best to be indoors in winter.

Second, ventilation to avoid the wind. "Take shelter from the wind like an arrow", because the pores are relatively open when practicing boxing, and it is easy to feel uncomfortable when being directly blown by the wind.

Third, the clothes are loose. Shirts and trousers should not be worn too tightly, and belts should be properly buckled. Shoes should be comfortable, not too tight and not too loose.

Fourth, prepare for activities. Be sure to do warm-up activities before exercise, such as stretching, bending, squatting, etc. Otherwise, it will easily lead to sprains, bumps and fractures.

Fifth, moderate exercise. The amount of exercise in Tai Ji Chuan depends on the length of exercise time, the speed, the depth of breathing, the level of work and other factors. The amount of exercise varies from person to person, so it is impossible to unify the regulations. After practice, you feel relaxed, open-minded, relaxed and refreshed, and there is no burnout below the waist. In order to prevent and treat diseases, don't do too much boxing. In particular, patients with hepatitis, infiltrative tuberculosis, visceral ptosis and coronary heart disease often have angina pectoris, so continuous boxing should not exceed 30 minutes, and it is not suitable to practice routines with fast jumping movements and difficult breathing adjustment. The average person practices continuously 1 hour, and the amount of exercise is generally moderate. Those who practice simplifying Tai Ji Chuan less than 3 times (or 88 times) can be regarded as a small amount of exercise. But people with a good foundation can sweat if they practice hard 15 minutes. Some people will feel chest tightness and breathlessness after practicing Tai Ji Chuan, even dizziness, nausea, shoulder pain, backache and backache. This is not to say that they exercise a lot, but to find reasons from technical problems such as exercise essentials and exercise methods.

Sixth, the posture is correct. We should do four things: first, relax and concentrate. The second is to get the power at the top and the tail in the middle. The head is straight and the neck is straight, and the collar is weak. The lips are naturally closed, the jaw is adducted, the tongue is flat, where to move, the eyes go first, the eyes move easily, the hand reaches the eyes, and when stopping, the eyes look forward through the index finger. The third is to sink your shoulders and elbows, and sit on your wrist to relax your fingers.

Seven, action specification. We should do four things: first, follow up with the waist as the axis. Here we should also focus on protecting the knee joint. Analysis, the main reasons are as follows: First, the joint activity is not enough before training. If you don't have enough activity, you start practicing boxing, and the muscle ligaments around your knee are still stiff. Inadvertent movements can cause knee sprains. Second, do not pay attention to rest and maintenance after practice. If you don't have a good rest after practice, it will make the leg muscles stiff and lead to knee joint strain. Third, the posture is not correct when practicing. The main reasons are summarized as follows: 1, kneeling. 2. Knee joints and toes of real legs can't be compared when they are fixed. 3, the action conversion can not be clear.

Eight, understand the truth.

Nine, persevere.
