The principle of muscle growth analysis of muscle growth

The composition of muscles:

There are many muscles in the human body, which are composed of muscle fibers and tendons. Each muscle fiber is very thin, but many muscle fibers are tightly arranged side by side. The tendon is located on both sides of the muscle fibers. One muscle generally has two tendons (such as biceps), three tendons (such as triceps) and four tendons (such as quadriceps). The muscles are attached to the bones. When a person wants to exercise, the muscle fibers contract or straighten, pull or push the bones to move.

"Muscle rebirth":

When a person is doing weight-bearing exercises, the muscle fibers in the exercised part are subject to force and contract or stretch. At this time, some muscle fibers will inevitably appear. The situation is that the muscle fibers are broken (but please rest assured that they can still grow well. These are just a small part of all your muscle fibers). When you finish your body training, the human body begins its own repair work. Your body will use a large amount of protein and other nutrients to reconnect the broken muscle fibers.

However, the muscle fibers after rework are not exactly the same as the original one, but are thicker and stronger than the original one. This is the instinct of human beings itself. After each training, some muscle fibers will become thicker and stronger, and this is how human muscles become stronger.

Five principles of weight training

"No exercise, no muscle gain":

Generally, when a person becomes adult, the number of his muscle fibers will not increase. Being stronger after exercise is entirely due to the thickening of each muscle fiber.

Sometimes, after multiple exercises, the muscle fibers can grow dozens of times thicker than before! Famous quotes in the bodybuilding industry: If a machine that can lift 120 kilograms of weight, the machine will be scrapped; if a person who can lift 100 kilograms of weight, then this Individuals will become people who can lift 120 kilograms! Therefore, only by constantly surpassing oneself can you become stronger! Of course, safety should be paid attention to. The intensity and time of exercise are also very different for people of different degrees, because once an injury is injured, it will not be worth the loss.

The principle of muscle growth is actually excessive recovery. After the muscle fiber is injured, it will be lower than the original level for a period of time, then exceed the original level, and finally return to normal.

If you practice too frequently, the muscle level will only decrease. Small muscle groups need at least 48 hours to recover, while large muscle groups need 72 hours. If you exercise excessively, you have to wait until the muscles are completely gone before going to the next time. Otherwise, you will become thinner as you practice... Only scientific training, timely supplement nutrition and ensure sufficient rest can you achieve rapid muscle growth.

Is it feasible to make muscles rupture and rebirth through slap?

"Muscle growth means that you use fitness to break the muscles first, and then you eat more to get the nutrients needed for muscle recovery. Finally, when the body is repaired, new, larger and stronger muscles grow..."

If the above answer is valid, then people can use wooden sticks to hit to increase their muscles. Anyway, muscle growth is mainly the regeneration after muscle breakage. If I want to grow muscles, I will first beat myself with a wooden stick to break the muscles all over my body, and then I eat more to get nutrition. In this way, when my body recovers, I can grow a more awesome body.

If this is true, there will be no need for a gym in the world. I should have a fight room...and then I want people with good figures to have a good body.

If this is true, there will be no need for a gym in the world. You can beat each other in the room to stimulate muscle growth and fat loss...

A reasonable pain should be felt, but it does not hinder the exertion of strength. You can complete daily activities and even participate in higher-intensity ball sports. In short, as long as you feel muscle pain or have obvious fatigue, don’t exercise this part of the muscle.

Only in this way can exercise help muscle growth. Beginners should find the strength that their physical fitness can bear as soon as possible to lay a solid foundation for future regular exercise. If you always think that it is congenital to grow muscles, you should be confident, find a set of training methods that suit you, or find an experienced coach. After practicing for one or two months, you will find amazing changes.
