I didn't sleep well during the exam. You should think that I didn't sleep well, and neither did others. Everyone will be nervous in the face of exams, so if you measure yourself, you won't put too much pressure on yourself. Review before the exam should be focused, especially to check the mastery of key content, such as the key content clearly specified by the teacher and repeatedly emphasized, as well as the weakest and often wrong places.

Stretching also needs to follow your physical condition step by step, and you can't force it or compare with others.

Static traction is the main method after exercise, that is, when the muscles feel traction, keep a fixed posture 15-30 seconds and pull each part 2-3 times. Runners often think that the greater the traction, the more painful the muscles feel and the better the traction effect. In fact, this is completely wrong! Too strong, so this is because: when the flexibility of a certain part of the body is insufficient, it will limit the range of motion of that part when doing actions, and the body will tend to use the help of another part (compensatory help from pectoralis minor muscle is not very good at stretching compared with pectoralis major muscle, and can not obviously feel the feeling of stretching. Because pectoralis minor is smaller and tighter. On the one hand, we stretch according to the physiological structure of pectoralis minor.

These five muscles are located in the upper limb, and all the movements of the arm are related to several muscles. Because the upper limb is used more frequently than the lower limb, it needs to be stretched frequently to keep the flexibility of shoulder joint and the healthy state of upper limb muscles.
