Good physical fitness is really good.

I have been out on duty many times recently, and I have to stand for seven or eight hours every time I go out on duty. This requires a very high physical fitness. With good physical fitness, I can finish the task happily and easily. After the duty, I can continue to exercise, continue reading and writing, and always be energetic. If you don't have enough physical strength, it will be miserable. I can barely support it when I am on duty. Low back pain is common. After the mission, you are exhausted. When I get home, I just want to find a place to lie quietly and slowly recover my strength. You don't want to do anything

? Physical quality is the basis of determining a person's happiness in life. Physical fitness is the basis for an ordinary person to achieve something. Physical fitness can be easily acquired by everyone as long as they spend some time every day. However, because most people don't know the importance of physical fitness, they never insist on exercising. Over the years, their physical fitness is getting worse and worse, and they feel very tired doing everything. They always want to find a place to rest. Life is not fun, only pain.

? Then how can we keep fit? Before getting physical fitness, we need to know what physical fitness is. Physical fitness includes two parts, cardiopulmonary function and strength training. With such a simple and clear definition, we can quickly gain physical fitness. If you want to have strong cardiopulmonary function, you can get it slowly as long as you keep running regularly. You don't need equipment training to gain strength. Equipment training depends too much on the venue environment, which is not conducive to persistence. As long as you can insist on doing push-ups and squats every day, you can do it. You may think that this simple and rude definition of physical fitness is not comprehensive, but it doesn't matter. As long as you can persist for a month, you won't doubt its role. If you can persist for three months, your mental state will change greatly. If you can persist for one year, you will never stop and accept this simple and rude definition completely, because your physical quality has undergone a qualitative change.
