? First, the process of exercise and fitness is the process of enhancing physical activity. Through physical exercise, we can promote the body's metabolism, exchange fresh air with the outside world, get rid of the old and welcome the new, enhance the body's microcirculation function, consume excess fat in the body, and excrete waste substances in the body through sweat and breathing.
? Secondly, exercise and fitness have many benefits, which can not only strengthen our physique and improve our immunity to the outside world, but also regulate our emotions and help sort out our negative emotions. When we meet unhappy people or things at work or study and feel depressed, we will go to the playground and run a few kilometers down. Through continuous breathing, we will spit out all the sulks in our chests, and our mood will be better and our mental state will be refreshed.
Thirdly, therefore, I think we'd better choose the outdoors when exercising. Outside, we will see the most desolate places more widely. Compared with indoors, an open environment will make our body and mind more relaxed and our spirit will become suddenly enlightened. When we exercise outdoors, our vision will be wider than indoors. Our eyes are the windows to the soul. Broaden your horizons and your mood will naturally get better. The so-called mind will be broader. That's the reason. If we exercise in such an open environment, our exercise effect will be more efficient and the results of physical exercise will be more remarkable.
Fourthly, one of the best benefits of outdoor sports is that we can breathe fresher air and enjoy more sunshine, which is more prominent than indoor sports. Under such conditions, our exercise effect will definitely get twice the result with half the effort. This is more beneficial to our health.
To sum up, I think it is best to choose outdoor sports if conditions permit, so that the sports effect will be more effective and outstanding.
