This is also the reason why many people can't persist in exercising for a while. Because I feel that fitness has no effect on myself, my figure is still the same as before, and there is not much improvement. Then I chose to give up, feeling that I just couldn't lose weight or grow muscles.
In fact, fitness is a long process, which does not mean that you can change your body shape by going to the gym several times. This is unrealistic. We should make ourselves more perfect through long-term exercise. This is not an easy achievement, otherwise there will not be so many people sweating in the gym every day.
Of course, we can't say that we practice like other people's majors and our bodies are perfect and strong. But we can work hard to improve our body shape and make ourselves look more perfect and confident. Then when we train, the most obvious feeling is that we are completely sore after training, especially after going back to take a shower, and the next day will be even more sour. This is the trace of fitness, which shows that you have practiced very well, and it will only hurt if you really practice to that extent. This is also a way to stimulate muscles. If you don't feel anything after practicing, it can only show that the intensity of your practice is completely insufficient and you can't achieve the effect of increasing muscles.
When we practice for a period of time, we can obviously feel some differences between our bodies. For example, you used to have a serious hunchback or a loose figure, but now it may be tighter. The muscles of the arms and chest are more integrated and no longer have any shape as before. Of course, this is all preliminary, and if you practice later, the effect will be more obvious. Anyway, you must stick to it.
