The principles of muscle building

Nowadays, more and more young people are pursuing perfect muscle lines, so they exercise their muscles frequently. However, some people feel very confused. They exercise every day, but the effect is not obvious. What's going on? In fact, this has a lot to do with our exercise principles. Only when we know the principles of exercise can we know how to exercise and achieve twice the result with half the effort.

1. 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 packed together. Tendons are located on both sides of muscle fibers. A muscle generally has two tendons (such as the biceps), three (such as the triceps) and four tendons (such as the quadriceps). Muscles are attached to bones. When a person wants to exercise, the muscle fibers contract or straighten, pulling or pushing the bones to move.

2. When people do weight-bearing exercises, the muscle fibers in the exercised part will contract or stretch under the force. At this time, some muscle fibers will inevitably break (but please rest assured that they can still grow back, these are only a small part of all your muscle fibers). When you rest after training, your body begins to repair itself. Your body moves.

3. Use a large amount of protein and other nutrients to reconnect the broken muscle fibers. However, the rebuilt muscle fibers are not exactly the same as the original ones. Instead, they are thicker and stronger than the original ones. This is an instinct evolved by human beings. After each training session, some muscle fibers will become thicker and stronger, and this is how human muscles become stronger. Generally speaking, the number of muscle fibers in a person will not increase after adulthood. Becoming stronger after exercise is entirely due to the fact that each muscle fiber has become thicker. Sometimes, after repeated exercise, muscle fibers can grow dozens of times thicker than before!

The above is our detailed introduction on the principles of muscle training. After our introduction, I believe everyone has a certain understanding of how to train muscles. Only by strengthening the muscles according to the principles of exercise, I believe the muscles will be thicker and stronger than before, because after exercise, each muscle fiber will become thicker, thus achieving the effect of strong muscles.
