On the supine bed, put an object with a thickness of 6 ~ 10 cm on the protruding part of the hunchback, relax the whole body, straighten your arms naturally, put your palms up and stretch your shoulders back, so keep lying on your back for more than 5 minutes, and do it 2 ~ 3 times a day. Sit or stand, hold the gymnastics stick with both hands, straddle your shoulders and back, hold your chest high, and stop when you feel the muscles in your shoulders and back ache. Do it once every morning and evening. Walking straight, doing homework and keeping a good posture, and good habits also affect the improvement of hunchback.
