There is a gym in the Mir space station. Is it novel to build a gym in a vast space? It still seems useless. There is no gravity in the universe, so this gym is of great use, because people don't exercise for a long time and are in a weightless environment, and their muscles will shrink. When we were on the surface of the earth, we kept exercising our muscles, but we just didn't notice it.

Astronauts are hardly affected by gravity in the universe. The gravity on the earth's surface is 9.8 N, but in the universe, this force is weakened, and almost no one can float freely in the air. It can jump very high with its feet. Although it was novel at first, it also brought some problems. For example, in such a weightless environment for a long time, people's muscles will shrink because they can't get exercise and don't need too much strength.

In order to make these astronauts who have been waiting in the space station for a long time get good health care and avoid being unable to adapt to the environment on the ground, the country has made such a gym in the universe. Of course, it is not like our traditional gym, because the traditional gym equipment is affected by gravity. You can exercise your muscles conveniently and quickly through it. He can only reach a strength limit through this mechanical transmission, so as to exert the exercise effect. Ordinary weightlifting.

Although the astronauts living in the space station will be replaced regularly, that is to say, they will be replaced as if they were on duty, but the frequency of that update will not be too high. After all, the economic energy spent on launching a spaceship is a natural number, so it will be replaced for a long time. In order to ensure your health, it is natural to make great efforts to maintain the life system. The gym in the space station is such an example.
