Your muscles use oxygen as food. So, when you don't breathe properly, your body doesn't get enough oxygen for the muscles to function normally. As a result, instead of using your

diaphragm to inflate lungs, your body starts using accessory muscles like upper back muscles to breathe. When you breathe this way, it forces your upper back muscles to constantly expand and

contract, which can cause discomfort and pain. When you breathe incorrectly, you hit your aerobic threshold faster. This happens when you struggle to breathe in enough oxygen, which causes

a buildup of lactic acid in the muscles. This can make you feel tired and cause cramps. Breathing properly ensures that your body gets enough oxygen and performs well. Here are three tips to
