It's just the difference in scope and intensity. Running in situ can reduce weight, but only after exercising for more than 40 minutes will the body fat be mobilized to supply energy with glycogen. If time is prolonged, the amount of fat energy can reach 85% of the total. Therefore, if you exercise for less than 40 minutes, fat consumption will not be too obvious regardless of the intensity. Only by consuming fat can we achieve the effect of losing weight. The best way to lose weight by running in situ: 1. You can't run without shoes. A pair of suitable running shoes has a great influence on the effect of running to lose weight, and it is best to have a foot pad. It's best not to run barefoot. Running barefoot will make the calf bear more force and do great harm to the foot. And the greater the weight, the greater the damage. It's best not to eat after running at night. If you are really hungry, you can eat some fruit. 3. Running must be effectively combined with diet control. Don't just diet without running, and don't just run without dieting. This will not only make you lose weight, but will rebound.
