1. Where is the shoulder muscle strain?

2. Identify the causes of shoulder muscle strain. Shoulder strap muscles include trapezius, rotator cuff, deltoid (front, middle and back), pectoralis minor, and even teres major, teres minor, supraspinatus and rhomboid. If you feel the trapezius muscle strain, it should be that the neck muscles are too weak and there is something wrong with the cervical spine; If it is a deltoid toe, it should be a positive load that causes the pectoralis minor muscle to tighten and the shoulder ligament to be damaged. If it is a middle beam, it may be the damage caused by the wrong posture and force habit; Usually hunched over, forming a round shoulder will also cause damage to the ligament.

When going to the gym to exercise, you should pay attention to the following points:

1. Always warm up fully.

2. Standards for ensuring action

3. Control the load. At the beginning of exercise, control the load at 70% of the maximum strength, and strive to repeat 12- 15 times in each group.

4. Fully exercise the shoulder strap muscles.

Step 5 relax after exercise

6. Ensure adequate sleep and nutrition.
