Running is a very simple sport. Some people will go running in Xiaoshi in their spare time, while others will choose morning running and fun running.

Then exercise is divided into high-intensity exercise and low-intensity exercise. For high-intensity sports, running is obviously not included.

First of all, aerobic exercise is a high-intensity interval training method, which burns calories through high-intensity exercise and rest, but the fly in the ointment is that it burns carbohydrates instead of fat.

So what we need to pay attention to at this time is how to run the five kilometers. If we run five kilometers quickly, or run five kilometers on the treadmill at the speed of 10- 12, and then have a rest, this is high-intensity exercise training, which can't achieve the goal of reducing fat, but only reduces carbohydrates in the body.

If it is a low-intensity exercise of 30 minutes to 60 minutes, such as jogging for five kilometers in about 45 minutes, or running for five kilometers at a speed of 6 to 7 on a treadmill, it is a low-intensity exercise and can burn fat.

At this time, not only the fat is burned, but also the carbohydrate, that is, the protein he keeps for our body, as well as the fat and carbohydrate. So jogging for five kilometers is good for us to lose weight and fat.

High-intensity exercise requires our heart to bear pressure, while low-intensity exercise means that the heart will not have too much load, but it will heat up after running.

So we need to choose whether to complete the high-intensity or low-intensity five kilometers according to our physical fitness.
