Humpback is a common abnormal posture, and the most common reason is poor posture. Many bad habits in our daily life, such as sitting for a long time and playing with our heads down for a long time, will put us in a forward flexion posture. The flexors such as pectoral muscles and abdominal muscles contract for a long time, while the extensor muscles of the back contract centrifugally and protectively. Therefore, in hunchbacked people, we can often see that erector spinae and erector spinae are extremely tight and developed. As the tension of the anterior fascia of the trunk shortens, the distance between the erector spinae on both sides will also increase.

To avoid hunchback, we need to strengthen these places: 1. Don't bow: the core stability is mainly transverse abdominis and erector spinae; 2. No hunchback: the stability of the middle and lower parts of scapula, rhomboid muscle and trapezius muscle, and extended to include latissimus dorsi; 3. Shoulders are not round: rotator cuff muscles, deltoid posterior bundle, teres minor, infraspinatus; 4. Don't probe the neck: the muscles behind the neck. Stretch the following places: 1. No humpback: pectoral muscles; 3. The shoulder is not round: deltoid toe; 2. Don't probe the neck: the front side of the neck.

Therefore, we can improve hunchback through fitness. Specific methods include: strengthening core stability, strengthening scapula stability, strengthening rotator cuff muscles, strengthening posterior neck muscles, strengthening pectoral muscles, strengthening toe of deltoid muscles and strengthening anterior neck.
