1 Run:
This kind of exercise belongs to anaerobic exercise, which is not helpful for fat decomposition because it needs oxygen. At the same time, this method will increase muscles, thicken legs and possibly gain weight. In addition, they consume more nutrients. If their nutritional intake can't keep up, it will cause adverse reactions, such as dizziness, cramps, hypoglycemia and so on.
2. Short-distance exercise: Generally speaking, the energy required for the first 30 minutes of physical exercise is provided by carbohydrates. When carbohydrates are insufficient in the body, fat will be used for energy supply. Short-term exercise generally can't reduce fat, and it's best to keep it above 1 hour.
3, the amount of large-scale exercise:
Many people think that the more you exercise, the faster you lose weight, and you will exercise a lot every day. Actually, it's not. On the contrary, a lot of exercise is not helpful to lose weight, because a lot of exercise often makes the output of the heart unable to meet the body's need for oxygen, so that the body can't use fat, but rely on carbohydrates for energy. At the same time, it will also produce some acidic substances that are not completely oxidized, which will reduce the body's exercise tolerance and is not good for weight loss.
