Fitness is actually a process of constantly breaking your original physical fitness and constantly improving. Generally speaking, it is a process in which human beings challenge their own limits. For example, you can only do 15 sit-ups at the beginning of fitness, and you can do 20 after training for a period of time. The process between them is not as simple as words, and you have to endure muscle pain and boring exercises in the middle. Fitness is actually "painful", and "pain" is only during strength training. Of course, we can also alleviate such "pain" appropriately. Scientific and reasonable training plan is the main condition, and reasonable diet is the important condition. Only by doing these two things well can fitness get twice the result with half the effort.

When you achieve something, the effect of fitness will appear immediately. You are not easy to get tired at work, because your muscle strength has improved and you can better cope with heavy work; Your mind is clearer at work, because your respiratory system has been exercised, which increases the ventilation in your lungs and makes oxygen more abundant; Your ability to cope with stress will be improved, because you will encounter many difficulties in fitness, and when you deal with these difficulties, it will also affect the way you usually deal with work and life.
