The change of fitness is slow, so many people insist on it for a week or even a month. If they can't see their great changes, they will choose to give up halfway. Even if they understand that fitness needs long-term persistence, short-term blows are really unacceptable to most people.
When we understand the importance of time, it is easier for us to be biased against fitness and do things that will change in a short time. However, if we really want to change ourselves or maintain a good physical condition, we must put down this concept of time and devote ourselves to fitness.
In fact, the effect of fitness is much more difficult. Observing with the naked eye, some data are also very unreliable, such as the change of one's weight. If there is a deviation in the way after fitness, for example, people who want to lose weight do a lot of muscle training, then they may gain weight.
In the long run, the effect of fitness will be much more obvious. You can try to take a photo of your physical changes every month, so that the changes will be easy to see, provided that the fitness continues.
The following are some reliable indicators that can be used to measure the fitness effect. The first is the fat content of internal organs, which is the key point for people who lose weight, and the real weight loss is to subtract this part, which is much more reliable than the overall weight of the body.
The second is the muscle content of the body, which is the key to test strength training or muscle gain. From the appearance of muscle changes, you may only see muscle edema, but the real internal changes are invisible to the naked eye, and muscle content is the breakthrough.
People who exercise regularly go through many processes, but it is this process that is roughly repeated, that is, the process of excessive muscle recovery. Simply put, after each training, from a microscopic point of view, the muscles will be torn, and this will not affect the whole.
These injuries can activate the repair system in the body, and the body will slowly reattach and stabilize the damaged muscles. Strengthening is an important step, and it is also the key point to gain muscle. After completing the process of excessive recovery, the muscles will become stronger and stronger to cope with the higher intensity load.
Repeat this process repeatedly, so that the muscles of all parts of the body can experience it many times before they can really become stronger. These are the general changes of muscles.
