The third misunderstanding; You can lose weight by jogging for 30 minutes at a time. Although jogging can achieve the purpose of aerobic exercise, it has little effect on losing weight. Practice has proved that only when the exercise lasts for more than 40 minutes can the body's fat be mobilized to supply energy with glycogen. With the extension of exercise time, the amount of fat energy can reach 85.5% of the total consumption. It can be seen that there is no obvious fat consumption in exercise shorter than 40 minutes, regardless of the intensity. Myth 4: The more intense the exercise, the more intense the exercise, and the better the weight loss effect. In fact, only continuous low-intensity aerobic exercise can make people consume excess fat. This is because during low-intensity exercise, muscles mainly use oxidized fatty acids to obtain energy, so that fat is consumed quickly. With the increase of exercise intensity, the proportion of fat consumption decreases accordingly. When approaching high-intensity exercise, the proportion of fat energy supply is only 155. Therefore, light, moderate, long-term low-intensity exercise or long-term exercise with heart rate 100- 124 beats/min is most beneficial to lose weight.
