Gym running is usually equipment running, because few gyms have a 400-meter track. Equipment operation means that the power of operation is transmitted in both directions, while the power of our outdoor operation is transmitted in both directions. Generally, equipment running is carried out at a constant speed, while outdoor running can change the frequency and rhythm at will according to the runner's rhythm, one active and the other passive. In fact, the effect of exercise is much worse. Breathing and heat dissipation are the most important. The outdoor air flow provides a good environment for the body to breathe and dissipate heat. As far as indoor is concerned, the air circulation effect of ordinary gymnasiums is not as good as that of outdoor. However, the advantage of this equipment is that you can still exercise in stormy days. For example, many places in northern China have haze, and many places in the north have haze. So for people who want to run every day, it is difficult to go out for a run in this weather.

Because gyms are generally equipment training, they can't exercise the flexibility and flexibility of the human body well. Therefore, it is best to go to the gym for running, swimming, yoga, martial arts, rock climbing, jumping and other training methods to increase the flexibility of the human body and achieve better fitness results. It feels much more comfortable inside, but if you want to exercise, it is recommended to go to the gym for pure running. Going out is more comfortable. Listening to a musical novel, I ran away unconsciously.

When we exercise outdoors, the air is fresher than the gym, the scenery is beautiful, and the crowd is not as crowded as the gym. No interference, no physical and mental freedom. The disadvantage of outdoor sports is that it is easily influenced by weather and natural factors. Training methods and hardware facilities are too simple. Generally speaking, outdoor fitness programs include horizontal bar, parallel bars, running, playing ball, rock climbing and mountain climbing. At present, the air quality in many places is very poor, especially after winter. We should choose suitable sports venues and methods according to the changes of seasons and climate.

I recommend gym training more. Because the gym has professional equipment and professional coaches. Each kind of equipment and apparatus is aimed at specific muscles and parts, and the exercise effect is particularly obvious. Professional coaches can teach you a scientific training plan and diet. No matter what the weather is like in the gym, you can train at any time. In addition, the fitness atmosphere is particularly good. You can help and guide each other. After the training, you can take a bath for free. To sum up, outdoor fitness is impossible. In short, exercising in the gym can effectively improve our fitness efficiency, achieve twice the result with half the effort and achieve the maximum fitness effect.
