In ancient times, people kept healthy by climbing mountains, running, lifting weights and some body movements similar to modern aerobics. Although the ancients did not have modern equipment, they did not slack off in fitness. Nothing can stop them from doing so. Even many modern people are not as healthy as the ancients! Ancient people can lift hundreds of kilograms of heavy objects, but modern people can hardly, which is also a manifestation of modern people's lack of exercise. Ancient people were very hardworking and hardworking. When they like something, they will stick to it and never give up. Many people have been exercising since childhood. Men practice martial arts, while women love music and dance. When they are bored, they can run and climb mountains. In ancient times, men were proficient in all kinds of martial arts since childhood. Riding a horse and shooting arrows is a matter of course. Many powerful masters can still fight against one hundred. It is not difficult to imagine that many men in ancient times were physically strong and extremely strong. At that time, it was estimated that male pectoral muscles were larger. It is said that there was a heavy object called a stone lock in ancient times, which was made of stone. It is specially used for physical exercise and can enhance people's arm strength. Many martial arts practitioners like to remove stone locks very much, because it can achieve very good results. This stone lock weighs several hundred Jin, and anyone who can lift it is very powerful. Modern people have modern equipment, but they often don't know how to cherish it, and they don't stick to fitness very well. They often fish for three days and dry their nets for two days, and hardly see any obvious effect. Many things, people who can't get them dream of getting them, but people who have them don't know how to cherish them. Although modern equipment is very advanced and the types meet people's various needs, not many people can really persist. There is no way to persist, and the natural effect is not obvious. Compared with the strength of ancient people, it is simply not a level!
