Which is better, outdoor running or treadmill? Nowadays, more and more people buy treadmills to exercise, while traditional outdoor running is gradually disappearing from the sight of urbanites. So can these two methods replace each other? The reporter interviewed Ms. Cheng Dantong, a famous fitness coach. She analyzed the advantages and disadvantages of the two sports. The advantages of the treadmill are: 1. It is not easily affected by weather conditions. In inland cities, the air quality is not very good. Sometimes there will be dusty weather in spring, and it is too cold and too hot to exercise. The indoor environment is quiet, the temperature is more balanced than the outside, and it can be simply worn. 2. Running in the gym can form a competitive atmosphere and achieve better exercise effect. You can also watch programs while running, and you don't feel too hard. The gym also has a personal trainer, who can give targeted guidance. Treadmill can also control the speed and mode, whether it is step running or slope running. Disadvantages: If you run on the treadmill, it will be boring and it will be difficult to achieve the expected exercise effect. In addition, some underground gyms are not well ventilated, which will also cause poor exercise effect. The advantages of outdoor running are: 1. You can fully enjoy the beauty of nature and fresh air. 2. Running around the block is free to set goals, such as setting the number of laps around office buildings and flower beds. Disadvantages: 1 The exercise effect in the morning is good, but some data show that the air quality in the morning is not the best in a day. 2. Outdoor running is generally on the roadside, and automobile exhaust is very harmful to human body. In short, the overall feeling is that running indoors is better than running outdoors. Of course, you must choose a well-ventilated and professional gym.
