During the period of hanging antibiotics, the body is weak and needs a good rest, because antibiotics will harm both harmful and beneficial cells in the body, so the body will be in a weak period.
If the intensity of fitness is high, it will consume a lot of body, and high-intensity training will make the body very weak. Some people who are in poor health will easily catch a cold and have a fever if they don't pay attention to nutritional supplements or keep warm after intensive fitness. However, if they are given antibiotics and exercise, their bodies will be weaker, and viruses will more easily invade their bodies and endanger their health.
