How long does aerobic exercise last?

Nowadays, people are more and more aware of health preservation, and many people will actively exercise their bodies in order to improve their body resistance and delay aging. Therefore, many people hope to do more aerobic exercise, but many people do not have a thorough understanding of aerobic exercise. So what is aerobic exercise? How long should aerobic exercise last? Let’s take a look together!

Generally speaking, the calories consumed before 30 minutes of aerobic exercise are provided by blood sugar and muscles in the body, and energy is provided by the decomposition of fat after 30 minutes. It is recommended to exercise for more than 40 minutes in order to burn some fat. Exercise before 40 minutes will not be very effective for weight loss. But it can still play a role in exercising the body and improving cardiopulmonary function.

There is no specific standard for the specific amount. After about 30 minutes of medium and low-intensity aerobic exercise, fat is mainly used as energy supply. The reason is that fat is mobilized more slowly as an energy source. But 30 minutes is not an absolute number. As your aerobic exercise capacity increases, the efficiency of fat mobilization will also increase. Marathon runners may start using fat for energy soon after they start running, while long-distance runners may start within 20 minutes. People who have no exercise habits may need more than half an hour when they first start exercising. The fact is, the human body mainly uses fat as energy reserves, and will generally actively reduce fat consumption for you. This is also the reason why losing weight is difficult, because your body will actively save fat for you as stored energy for future food shortages. This is a biological instinct. As you increase your aerobic exercise, your body will become more and more accustomed to having you burn fat.

The longer you exercise, the more fat you will burn. As long as it lasts for half an hour to an hour, 50% of the calories consumed will be supplied by burning fat. If you don't diet, even an hour of aerobic exercise can only burn the starch and fat in the food, but not the fat accumulated in the body, which is still not helpful for weight loss. After dieting, the longer the aerobic exercise time, the more chance it has to burn fat in the body. This is the real exercise for weight loss.

Generally speaking, exercise that lasts for more than half an hour is considered aerobic exercise. If you want to lose weight through exercise, each exercise should be no less than 40 minutes. There are many ways to do aerobic exercise, such as jogging, sprinting, and walking. You can also skip rope, do yoga, dance, etc. However, if you want to achieve the goal of losing weight through exercise, you must persist.
