Absorption rate, for people with high food absorption rate, fitness will have a better place than ordinary people. It is very important that most of what they eat can be converted into what the body needs. Some people eat the same things as others every day, but their bodies are different from others. If everyone does about the same amount of exercise and eats about the same amount every day, some people will look stronger, some people will be thinner, and stronger people are more suitable for fitness.

Fitness consumes physical strength, let alone fitness if you don't even have a figure, so having a good physique is the basis of fitness. I'm talking about people who look strong, not fat people who turn all food into fat. People have three horizontal lines of low, medium and high absorption rate. Low absorption rate will make them very thin, while high absorption rate will make them particularly obese. Only those with high absorption rate are more suitable for sports, and in the process of sports.

The process of fitness is very tired. If you don't have good endurance and willpower, you can't improve your physical fitness through fitness. So fitness people need people with excellent willpower and endurance. How to reflect the level of willpower and endurance? Willpower depends on your specificity in doing one thing, that is, how long you can persist in the process of exercise, and endurance depends on whether you can continue to exercise in a state of physical fatigue.

There is a kind of exercise that is easy to distinguish willpower from endurance, called running and long-distance running. Long-distance running requires endurance. With enough endurance, you can cross the finish line. Speed and ranking are not important, but how far you can run is the place to show endurance. The higher your endurance, the longer you will run. People with weak endurance may be exhausted after running 500 meters, but this endurance must be exercised the day after tomorrow. Whether you are willing to exercise endurance can also reflect your willpower.

In long-distance running, the embodiment of willpower is how far you are willing to run when you are already very weak, whether to give up immediate rest or run for a while, or not to reach your limit, hoping to break through your limit. This power is called willpower. The stronger the willpower, the faster the muscles grow in the process of fitness. Of course, willpower can also be improved through exercise the day after tomorrow, but how much it can be improved depends on yourself.

There is also an observable standard between human bodies, that is, achilles tendon. People with long achilles tendon are especially suitable for sports. This thing is born and can't be improved the day after tomorrow. Pay attention to people around you. The better the bounce, the longer his achilles tendon. Pay attention to those NBA stars. Everyone's achilles tendon is very high and looks beautiful and harmonious. The position of Achilles tendon is the position where the muscle breaks from heel to calf. These are me, as shown in the above picture.
