What does 40 minutes of aerobic exercise do?

People need energy to live, and fat is the main source of energy for humans. So even when we are sleeping, playing games, or eating on the floor, our bodies are still consuming energy. Therefore, if we also do aerobic exercise, the body will consume more energy. This is a great opportunity for people who want to lose weight. So how long should we exercise? How long does it take for the body to burn fat?

It depends on the intensity and duration of your aerobic exercise. Generally, you need to maintain 65% to 85% of your maximum heart rate and persist for more than 30 to 40 minutes to start burning fat. However, sticking to anaerobic exercise and increasing muscle mass can also help lose fat, because muscle can increase your basal metabolism, prevent fat accumulation, and help you burn fat 24 hours a day.

When you first start exercising, you will feel particularly strong. This is because you are using the glycogen in your white muscles, which is the most efficient and powerful exercise. It does not require the use of nutrients in the blood and is called anaerobic exercise. After a while of exercise, the glycogen in your white muscles is burned out, and you will feel that you have entered a "false fatigue period." Next, your red muscles are moving, and they need to consume nutrients in the blood. The nutrients in the blood come from fat and other substances stored in the body, which are produced by the reaction with oxygen inhaled. So the subsequent exercise is called aerobic exercise. Only aerobic exercise can burn fat, while anaerobic exercise is strength training used to stimulate muscle growth.

When you enter the "false fatigue period", it is almost the time when you switch between anaerobic and aerobic exercise, and the subsequent exercise will burn fat.

So it is very simple for everyone to lose weight through exercise. You should not be afraid of losing weight or worry about not having time. The key is to make up your mind to start losing weight, so that you can have the perseverance to stick to it. For us, perseverance in doing things is what we lack the most, so we should reflect on ourselves.
