Round shoulder hunchback Round shoulder is usually accompanied by hunchback. Round shoulder is not only a physical problem, but also affects the training effect of upper limbs. Doing chest pushing, rowing and other upper limb movements, sending too many shoulders, leading to incorrect force, exhausting the shoulders first, it is difficult to train the target muscles in isolation. Moreover, the range of motion of the shoulder joint is small, and even the flexion and extension of the back arm of the neck can't be done. At the same time, the pectoralis minor muscle pulls the shoulder forward and inward, and the shoulder is visually narrower. As for the back, pull-ups should not be done to the back muscles, but to the trapezius muscles and arms. Of course, these are all issues that fitness people care about. For ordinary people, the most direct and important words are three words, no! All right! Look! Round shoulders lead to the development of trapezius muscles, that is, sliding shoulders. After the shoulders are pulled in, the front looks narrower. Therefore, the problems of shoulder slip, round shoulder and humpback correction are all carried out at the same time. Shoulder roundness is mainly due to tight pectoralis minor muscle and weak back muscle. The consequence of round shoulders all the year round is that the pectoralis minor muscle, like a steel bar (according to the body coach), lacks elasticity, is prone to fatigue and recovers very slowly. Anatomical position of pectoralis minor muscle. Pressing the pectoralis minor directly presses the small muscles of the shoulder fossa. Although hunchback is theoretically due to weak back strength, it is necessary to exercise the back, but relaxing the pectoralis minor muscle and restoring its elasticity is the basis for exercising the back to restore the body to neutral position. Now I know why it is always difficult to exercise your back when you enter the gym-the range of motion of your upper limbs is not enough, and you can't use your target muscles correctly when rowing. The pectoralis minor is like a small apple, you can't love it too much. Of course, on the one hand, hunchback with round shoulders is a common problem, which almost everyone has before exercise. On the other hand, pectoralis minor is a well-deserved "king of compensation". Not only all upper limb movements such as chest pushing and rowing, but also leg movements such as hard pulling and arrow squatting.
