Exercise is more than consuming energy.

The definition of physical fitness in Baidu entry is: physical fitness is the basic athletic ability of the human body through sports qualities such as strength, speed, endurance, coordination and flexibility. Physical fitness is the basis of doing everything, the ability to adapt to everything and the basis of energy management. The most important thing to improve physical fitness is exercise.

I used to equate exercise with losing weight. I think exercise is sweating, selling strength and consuming energy. After exercise, you will be very tired and have less energy to do important things. The energy management manual has subverted my cognition. Alina Zhang, the author of this book, is a workaholic to the core, but she has made an iron law for herself: Exercise is greater than work. What do you mean? It is she who gives priority to exercise in all her work, no matter how busy she is.

Why? Because she keeps exercising, she can gain physical strength for overwork. She is imitating those entrepreneurs. She observes entrepreneurs whose time is more precious than gold. It stands to reason that they are several times, ten times and dozens times as busy as ordinary people, but they exercise every day. They do this not because they have money and nothing to do, nor just to keep healthy, but to gain enough physical strength to support overwork. So Alina Zhang said, "Motion is not energy output, but energy input."

My understanding of this sentence is: on the surface, exercise is to output energy and consume energy, but in fact, exercise is an energy investment, just like doing a profitable business. You need to invest the cost first, and then you will come to Qian Shengqian and get rich returns. The same is true of the influence of exercise on energy. You need to put your energy into it from the beginning. You pay some energy, and your physical fitness will get better and better after a while, which is equivalent to getting those energy back with interest.

Looking at sports from the perspective of energy management has brought me a lot of inspiration. First of all, there are fewer times to be lazy in sports. Every time in the gym, I always complain that the coach is too strict when I can't persist, and I try to stay in the comfort zone. Now I think exercise is to input energy to myself and I don't want to be lazy. Secondly, the initiative has increased. We all make excuses for not having time to exercise, and I used to. But from this perspective, if you don't improve your physical fitness through exercise, how can you cope with heavier work?

So motion is essentially an input of energy.
