Just like us, going to the gym is called exercise, and running in the playground at night is called exercise. Is walking on the way to and from work called exercise? If we say sports in a broad sense, of course, but we need extra sports because we realize that there are too few opportunities for us to exercise in our work and life. Sitting for a long time and unhealthy food put a load on our bodies, so we need extra exercise.
Animals have no such consciousness, because their living habits, recipes and nutrition are the most reasonable after a long evolution. Nature is cruel and survival is difficult, so for wild animals, it is exercise.
For pets or zoo animals, life is superior, there is no challenge, and there is no need to run around, which is easy to cause obesity or rich diseases.
There is deliberate exercise in the animal kingdom, but it is not out of animal consciousness but nature. Carnivores such as butch, leopard and wolf will play with their prey in their childhood, and even catch them repeatedly. This is because they are training their predation skills so as to become excellent predators in the future and not starve to death.
In addition, like bears, there are often two or three cubs born in a litter, and what cubs like to do most is to chase each other, even seemingly fierce fighting, which is also a form of exercise. They gain stronger, more soulful, agile and balanced bodies through this kind of fighting behavior. In fact, there was a similar situation when human beings were young. This is not an active sport, but when they are young, they like chasing and fighting. When they grow up, it seems to be true.
