Generally speaking, aerobic exercise begins to enter a relatively high level of fat burning in about 20 minutes, so we generally recommend that you do aerobic exercise for more than 30 minutes, otherwise the effect of reducing fat is very poor, time is spent, but the effect is not good, so futile things should be avoided.
However, when the exercise time reaches a certain level, people consume more than just fat. At the beginning of aerobic exercise, we will consume a lot of glycogen stored in the body. You will feel relatively relaxed at this time, so you won't be too tired at all. After half an hour of exercise, you will feel very tired and lack of water. When your exercise time reaches about 1 hour, the fat energy supply can't keep up, and you will feel more tired because of lack of oxygen and water. At this time, you will start to break down the protein energy in your muscles, which means that your muscles will slowly lose, and then your basal metabolism will also decline!
What you need to lose weight most is not how strict your diet is, nor how much exercise you do, but whether your physical condition is suitable. This physical condition is your basal metabolism, accounting for 65%~70% of our total human consumption. It can be seen that this ratio is huge, so your basal metabolism has dropped. Even if you eat less, you can't use it all, let alone one.
Therefore, the longer the aerobic exercise time, the better, and the effect of reducing fat is not necessarily. Many people jog for more than 20 kilometers and it takes about a week to reconcile, not because of poor physical fitness or poor physical fitness, but because the consumption is really great. Generally, after such a long-distance exercise, their weight will drop by 3 to 7 kilograms. It's not that you eat so much fat, but that the water, muscle mass and fat in your body are all there.
Less fat is a good thing, less muscle is not. Many bloated people have too much fat, but very little muscle. This kind of people are in poor health, poor resistance, always prone to illness, and it is not easy to get well after taking medicine. This is because their own basic metabolic ability is poor, and there is no way to resist the virus and use drugs.
Although it is in the fat-reducing period, you should arrange strength training once or twice a week to ensure your muscle mass and athletic ability and lay a solid foundation, so as to lose fat successfully!
