The first is the running time.
When the body is doing aerobic exercise, our body needs to continuously provide calories to maintain the exercise. At first, our bodies consume sugar and fatty acids to support us, and then we consume fat. After 30 minutes of exercise, the sugar has been consumed and the body's fat has begun to be consumed.
So generally speaking, when we are running, we should try to extend the time to more than 30 minutes in order to lose weight and achieve the effect of slimming. In the early stage of losing weight, you should not only pay attention to speed, but also care about time. Because if you run fast, your body will be exhausted and you won't have the strength to continue running. At this time, your body has not consumed fat, not only has no fat-reducing effect, but also is prone to injury.
