With the development of social economy, people no longer need to worry about food and clothing. On the contrary, people began to pursue the quality of life more. Some people may be out of shape because they don't exercise much or eat too much, such as having a beer belly. Therefore, it is also to find business opportunities in the market. There are many gymnasiums in the city now

The coach in the gym always has big muscles, which makes many male students envy him and expect him to exercise such muscles. However, the gym is also a consumer place after all. Let's look at some people who work on the construction site. Their muscles are not exercised in the gym, but at work. So, who is the stronger muscle of these two people?

Actually, this is not easy to judge. The theory of red muscle and white muscle circulating on the Internet is not comprehensive. In terms of strength, it is true that the muscles of migrant workers should be stronger. After all, the muscles of migrant workers are trained at work, while the muscles of fitness coaches are trained in the gym, so they have no actual combat experience.

Moreover, some fitness instructors will specially eat protein powder in order to practice or maintain muscles. Migrant workers have been relying on high-intensity work to maintain their muscles, which is more of a helplessness. However, it is precisely because of the high intensity of work that some migrant workers are still struggling in physical discomfort for their livelihood, which leads to various problems, such as arthritis. However, the coach in the gym will pay attention to his physical condition during exercise, and the possibility of injury is relatively small.
