The single consumption is too low, such as 20 minutes. My own experience is that it takes at least 40 minutes each time to have obvious effects.

Never mind, the principle of losing weight is that the calories consumed, calories consumed = resting metabolism+exercise metabolism, that is, resting metabolism+exercise metabolism-calories consumed. This formula is greater than zero, and it is better to have an obvious calorie gap. Eating more than moving, running is useless;

Giving up too early, many people give up after running for two days because they feel useless. Don't weigh yourself every day when you lose weight. Even if you do nothing for a day or two, people's weight may change. The change of weight depends on a long time, usually once a week;

Fishing for three days and drying the net for two days, even if 1, 2, 3 are all done, but if you only run once a week, the effect is not obvious. If you want to lose weight obviously, run for 40 minutes at least 4 times a week 1, because on the day when you don't run, the calories consumed are basically accumulated;

I don't encourage you to use radical methods, but if you want to have obvious results, you need to pay something. When I lose weight by myself, I only rest one day a week, run once in the morning and evening, and have equipment at noon. At this speed, I can lose 4 Jin of pure fat a month.
