Round shoulder is an abnormal shoulder shape with both shoulders forward caused by an imbalance in the strength of the shoulder and back muscles, also known as chesty.
In daily life, working with the head down for a long time or walking in an incorrect posture may cause the middle and lower trapezius and rhomboid muscles to relax, but the muscles in the back are too tense, thus resulting in the symptom of both shoulders moving forward. In addition, often carry heavy things, will make the shoulders under certain pressure and gradually form round shoulders.
Therefore, you should improve the posture of working with head down and move your neck after working for a period of time to reduce the imbalance of muscle strength in the shoulders and neck. At the same time, we should pay attention to stretching the muscles of the shoulders and neck, and practice the chest muscle groups appropriately.
