Think more about the strange state of human beings before 5000 years of civilized life. During this time, human beings have evolved and adapted to something, that is, food shortage.

The initial exercise begins to consume energy in the body, and then the body will find that it needs to consume a lot of energy every day, and such consumption requires strength. So I began to store energy as much as possible (in muscles, in blood, in fat). Thereby increasing muscle thickness and strength, and storing fat to cope with consumption. This is why exercise should be combined with diet.

But there is another way. Do pull-ups, push-ups, squats, handstands, and running. ...

Let your own strength lift and move your body, then your body needs to consider another question: how to complete these actions more effectively? The answer is to enhance muscle strength and lose weight. …………

Also, the rebound of sports is inevitable, because the body is consumed as much as possible, because more years need to consider the continuation of human beings, rather than a healthy life and a strong body. Therefore, it is very important to stop eating after training (you will be hungry and need to store energy).
