1. Insufficient muscle strength: Pull-ups need enough muscle strength, especially in upper limbs, shoulders and back. If the muscle strength of these muscle groups is insufficient, it is difficult to complete the whole movement or only part of it.
2. Insufficient flexibility of shoulders: If the flexibility of shoulders is insufficient, it may lead to tension and jamming of shoulders when doing pull-ups.
3. Improper action skills: Pull-up skills are also an important factor affecting the degree of action completion. If the movement skills are improper, it is difficult to coordinate the muscle groups correctly and affect the completion of the movement.
4. The influence of other physical conditions: Some physical conditions, such as shoulder injuries or other health problems, may also lead to the shoulder getting stuck when doing pull-ups.
In order to solve this problem, you can try the following methods:
1. Enhance muscle strength: Enhance the muscle strength of upper limbs, shoulders and back through targeted exercises, such as dumbbells, push-ups and sit-ups.
2. Increase the flexibility of shoulders: You can increase the flexibility of shoulders by doing some stretching exercises, such as hanging horizontal bars and stretching shoulders.
3. Learn the correct action skills: You can refer to professional fitness guidance or video tutorials to learn the correct pull-up skills in order to better coordinate muscle groups.
4. Check physical condition: If the shoulder is often stuck, it is recommended to check whether there is any injury or other health problems in the shoulder, and seek professional advice from a doctor if necessary.
In a word, to solve the problem of shoulder sticking in pull-ups, we need to comprehensively consider many factors, such as muscle strength, shoulder flexibility, movement skills and so on, and then make targeted improvements and adjustments.
