2 Breathing style is also particular. Many people like to walk hunchbacked, and even do everything hunchbacked. This looks not only insecure, but also ugly. More importantly, this way of breathing is also wrong. When breathing, it is best to alternate. Chest out when exhaling, chest out when inhaling. This is also very beneficial to promote the development of your chest.
Whether standing or sitting is correct or not, if you always live in a hunchback way, the harm is very great. It will not only oppress the development and growth of the chest, but also easily lead to sagging. Therefore, whether you are standing or sitting, you should maintain a good posture. Holding out the chest is the foundation, so as not to fall into the predicament of hunchback.

But if you are always ashamed to wear underwear, it is also very bad, and it is easy to cause sagging or even injury.
