Myth 1: Be sure to eat enough before exercise.
Many people think that they should exercise after eating. Lack of food can lead to hypoglycemia, dizziness, fatigue and even fainting. But in fact, full exercise is harmful to health.
After meals, a large amount of blood flows to the digestive system, especially the gastrointestinal organs, to ensure the supply of oxygen and nutrients needed for digestion. If strenuous exercise is carried out at this time, a large amount of blood will flow to the moving organs, especially the limbs, to ensure the needs of muscle work, thus causing insufficient blood supply to the digestive system.
Therefore, drink a glass of milk before exercise and supplement some healthy snacks, such as cakes or bananas, as long as it can meet the basic energy needed for exercise.
Myth 2: Not suitable for pre-meal exercise.
American studies have proved that one to two hours before meals, quantitative walking, dancing, jogging and so on. An empty stomach helps to lose weight.
Because during physical exercise, the motor center and sympathetic nerve of the cerebral cortex are highly excited, while the food center is relatively inhibited, and the secretion of digestive glands is inhibited. Therefore, it can reduce people's appetite and reduce food intake.
At the same time, exercise before meals can also effectively eliminate fat, consume less calories and will not affect health.
Myth 3: 30 minutes of exercise is enough.
Why do many people insist on exercising every day, but it is useless to lose weight? Because most people are sweating after 30 minutes of exercise, the feeling of achieving the effect is over. But these people were too tired to talk, and they gave up before the effect was about to take effect.
This is mainly because it takes 30 minutes of continuous exercise, such as jogging, before the body starts to consume fat. Jogging can reach the stage of burning fat during aerobic exercise, and the jogging time should not be less than 40 minutes at a time. The main thing in the early stage is to consume your water, and then you can really burn fat effectively.
Myth 4: The more intense the exercise, the easier it is to lose weight.
It is wrong to think that the more intense the exercise, the easier it is to lose weight. Continuous low-intensity exercise can achieve real fat burning effect, and the more exercise, the smaller the proportion of fat consumption. The most effective way to lose weight is to keep the heart rate at 100- 124.
