This is normal psychology. Muscular development means being strong and healthy, and it is a symbol of men. This is related to the evolution of our genes. In ancient times, the natural environment was harsh, the strong man had strong labor ability, gained more prey, had a competitive advantage, and could obtain more resources, including women, of course, so his genes were easier to spread.

Strong muscles mean that people are healthier and people want to be stronger. Up to now, it is no exception, not only to be strong, but also to look symmetrical and beautiful. Fitness was introduced to China from abroad. In recent years, fitness has developed rapidly in China, and our bodies will produce dopamine during fitness exercise, which is exciting.

This is why I feel addicted when I practice to a certain extent, and suddenly I feel uncomfortable when I don't practice. Of course, it is not easy for everyone to build a strong muscle, and it takes too much effort to make people satisfied. This is related to personal genes, and with the prevalence of fitness in recent years, it is not surprising that more people naturally want to develop good muscles like those great gods.

Now we also advocate national fitness. More and more people pay more attention to health and fitness exercise. More people want to build muscles, and I am one of them. I feel uncomfortable without practicing for two days. I started exercising because I wanted to be stronger. When I started to exercise with others, I began to observe my exercise parts!

At first, I began to practice my chest muscles, and then my muscles will be sore, but my heart will be very cool, because my muscles will be hard when I work hard, and I feel a little psychologically grown up. After exercising other parts, although I can't see any change, I still feel very cool in my heart.

After several exercises, I gradually got into the habit of exercising. Although the process is painful, the joy brought by physical changes is indescribable. I fell in love with myself.

When exercising, you can break through the limit and constantly challenge yourself. The five indicators of speed, endurance, strength, flexibility and balance have all been improved, which is very fulfilling. Good figure will attract the attention of more beautiful women, have good immunity, feel happy and have a sense of accomplishment when exercising, chat with fitness people and make more friends. What's wrong with that? People have to have a hobby.

I was born with weak constitution, small muscle mass and small skeleton. When I first went to exercise, it was hard to bench press 40 kilograms. See others bench press 80 kg, 100 kg, I feel envious. Now I can bench press 80 kilograms, and I don't expect any more. After all, my physical condition is too limited, which has exceeded the intermediate level. I am also very satisfied. Squat can also be close to the intermediate level, only the hard pull has just passed the primary level and is the weakest.
