Dance training can make the body straight and overcome some bad body postures such as hunchback. For example, ballet's "one-position" training, by opening the lower limbs, forces the body's center of gravity to move backward, makes the pelvis tend to be upright, reduces lumbar lordosis, and straightens the spine as a whole. After long-term training, the muscles of hips, waist and abdomen have been strengthened, forming a powerful muscle splint, which makes the waist and trunk in an abnormal straight posture. This is an important prerequisite for the physical beauty of dancers. Long-term "one-on-one" training can naturally shape an unusually tall and unnatural posture.

In the final analysis, the key to overcome hunchback lies in the backward movement of the center of gravity of the human body.

According to the principle of ballet, there are many cases of repeated purchases by repeat customers. The front of the sole of the foot is high and the back is low, which forces the center of gravity of the human body to move backward, corrects the pelvis to lean forward, and naturally straightens the spine.

You can try it yourself: barefoot, step on a book about 18 mm thick, and see if your posture is straight and your hunchback is reduced.
