About 40 minutes of aerobic exercise only metabolizes the sugar in the blood, but it can't reduce fat.
Fat metabolism takes 40 minutes, so you should stick to it for at least 40 minutes.
It is important to do activities before and after exercise. Warm-up activities before exercise can prevent muscle and bone injuries, and can also cushion the burden of sudden exercise on the heart and lungs.
Don't sit down and rest after exercise. Exercise for at least 10 minutes to help the heart and lungs relax. Stretching after exercise can help you shape your body and make your legs straighter and more beautiful. If you sit down and rest at this time, your hips will sag and your thighs will become thicker. We must seize the critical moment.
