To treat humpback whales, we must first understand humpback whales. Humpback, also called round back, is a manifestation of spinal deformation. There is no medicine for humpback in clinic, and it can only be corrected by physical therapy. The principle of correction is to strengthen the strength of back muscles, stretch the length of trunk, expand the scope of chest and pay attention to sitting posture. You can use orthopedic supplies such as your back for humpback. Usually pay attention to maintaining the correct posture, and often remind you to hold your head up and hold your chest high. In addition, you can try to do the correct stretching when sleeping: lie on your back, your feet are shoulder width apart, your knees are together, your hands are above your head, and your palms are opposite.
According to what you said, you want to learn to dance to correct your hunchback, but the influence of dancing on hunchback is not so great, because although you have enough time now, you will temporarily stop dancing when you are busy, so I suggest you change the correction method. For example, humpback can be corrected by tension rope, which is not expensive. Ordinary words, a meal can be done. You can completely correct hunchback by simply exercising your back and chest.
