They don't have the help of these fitness equipment, such as treadmills, barbells and so on. They don't have these external things to help them exercise. If they want to exercise, they can only rely on themselves. Many of their sports are not helped by other external tools. For example, running can only go to the playground, the street or other open places on the road, but there is no way to exercise on the treadmill.
If they want to run, they may not be able to run indoors, because now they can exercise indoors on a treadmill, and in the past, there was no way to run indoors at all. Many of their sports may have to go outdoors because the corresponding conditions cannot be provided indoors.
However, outdoor sports can be carried out when it is relatively empty, but now many people can exercise directly indoors, because there are corresponding machines to support fitness, so it is not so troublesome. Suddenly found that compared with the past, we are really happy to live in the present, unlike the last century, many things are underdeveloped and many things do not exist.
We are very happy now, technology is so advanced, there are more and more intelligent machines, we can get support and help, and we can provide good economic conditions. We should cherish the existing resources and strive to build a perfect body. We can't live up to such a good condition now, don't you think
