How is the 0 1 hump formed? Due to long-term bad sitting posture, including chest hunchback and sedentary, the pectoralis minor muscle is passively shortened, and the shoulders become forward or downward, which will form a round shoulder hunchback. If you go on for a long time, your muscles will be tense and stiff, and if you don't correct them in time, it will affect your body.

Find a fixed object, lift your right arm, with your elbow higher than your shoulder joint and your forearm perpendicular to the ground. Chest out and abdomen in, legs in lunge, ipsilateral legs in front. When stretching, you will obviously feel the tension and stiffness of your muscles, and you will feel a little pain. Hold on for half a minute and do the same on the other side. This will stretch your pectoralis minor.

Chest-expanding exercise, the gymnastics done in the student days, is still very useful, especially chest-expanding exercise, with feet shoulder-width, chest and abdomen, arms open, back stretched as far as possible, and head tilted back for more than 20 minutes every day, which will also improve round shoulder hunchback.

The most important thing is the usual sitting habits. Don't sit still. Get up every half hour to exercise, stretch, twist your neck, do stretching exercises, and find a door and window after studying and working. Hold the doorframe with both hands, lean forward, and keep your legs in a lunge position for about 15 seconds at a time. Be careful not to push too hard.
