First of all, people who go to fitness basically use treadmills, but the purpose of running is to prepare before fitness (or warm up) and organize after fitness. In fact, a few people use it to improve heart and lung function. In this sense, running on the treadmill is only an auxiliary means of fitness, not the main means of fitness. There is another kind of people who go to the gym for running with a clear purpose, such as losing weight. They don't love running, but use running as a means to achieve their goals. Most of them don't have the courage to brush circles or run on the playground, or they may be ashamed to run with others. It's different in the gym. No one has time to mind other people's business, and there are not a few people who exercise with the same purpose as them. To put it bluntly, it means spending money to consume that kind of environment, and it is also consumption, but it is different from the personal value orientation of the subject.

People who go to the playground to brush circles or run on the road are often people who really love running. They ignore other people's strange eyes and immerse themselves in their own running. They run with a certain purpose, but they can endure the loneliness that is not understood. Therefore, such people can run half a horse and all horses, while people who run on treadmills can only participate in healthy running.

Secondly, the exercise effect of the two is very different. When running on a treadmill, people are passively led by running, and their toes don't have to push the ground. What people do is only to maintain the coordination of the body. Therefore, running on the treadmill, people's consumption is not great.

Running on the road is different. Adjusting speed by stepping on the ground and swinging your arms is a force at work. This is why people without muscle strength can't run fast. In addition, the road environment of road running is much more complicated than that of treadmill, so the use of core strength in this case is particularly important for running, an unbalanced sport. This kind of running, people must actively participate in order to make running lasting, and how far they run is determined by their physical strength and endurance.

Finally, running on a treadmill is generally difficult to run at will. Adjusting the speed to 1 1 is already a good speed. If it is adjusted to 13, it may run bang. At this time, the management of the gym will come and stop, demanding to slow down, for fear of accidents. This is an important reason why runners are unwilling to use treadmills. If you run the highway, you can run as fast as you want. Therefore, the marathon gods are all from the master walkers.
