Shoulder is the most important strength activity hub area of upper body. If there is anything wrong with the shoulder, it will seriously affect daily activities. Shoulder joint problems, as long as the daily activities require arm movement, the arm can not exert force and the lifting is limited. Shoulder is a very important movable joint, so it must be protected during training. If a bodybuilder fails to protect his shoulders in training, it will be very dangerous, which will not only increase the safety risk of training, but also increase the pressure on the shoulder joint and cause shoulder joint injury if the training movements and postures are not standardized and the training weight is not appropriate.

Shoulder injury is not only as simple as affecting training, but also difficult to recover after shoulder injury, which takes a long time to recover. Even after recovery, it is difficult to reach the best state of injury training.

Therefore, the trainer must strengthen the training and protection of the shoulders and strengthen the strength of the rotating muscles, especially when training the shoulders, or carry out special strengthening of the rotating muscles from time to time. Only when the muscle strength of the rotator is improved can the wear of your shoulders be reduced in long-term training. The rotator muscle group consists of four small muscles, including supraspinatus, infraspinatus, subscapularis and teres minor. These four small muscles are very important. They control the stability of the shoulder joint, the stability and movement of the shoulder, and are all dominated by the rotating muscle groups.

Training movements that require a lot of shoulder rotation need to be maintained by rotating muscle groups. That is to say, in fitness training, as long as your arms are active and your shoulders are involved, then the rotating muscle group will participate in the protection of your shoulder joint during training. If your rotating muscle group is not strong enough, your shoulder stability will be weak during training, which will increase the risk of training injury, especially when the trainer uses heavy load training, the shoulder rotating muscle group is weak, which will directly increase the risk of injury. Therefore, it is necessary to strengthen the rotating muscle group frequently.

When our arm is raised, the rotator cuff covering the tubercle will push up, and then it will rub the bone at the acromion. When the rotator cuff rubs and squeezes against the acromion for a long time, part of the rotator cuff may break due to wear, which is commonly known as rotator cuff tear. Moreover, as long as there is 1 muscle in it, it will directly or indirectly affect other muscles and even other joints.

Here is a set of intensive training for shoulder rotation muscles to make shoulders healthier and enhance self-protection function. Pay attention to this group of movements during training, not fast. It is very important to move quickly, which will not only affect the effect, but also increase the shoulder pressure.
