The United States, Britain, Canada and other countries advocate their citizens to exercise at least five days a week. Because there will be some positive reactions after every exercise, and these benign reactions will last for a while.
For example, the effect of blood pressure drop after exercise can sometimes last 12 hours; The decrease of plasma triglyceride concentration after aerobic exercise can also be maintained for several hours. Therefore, in order to maintain the benign effect after this kind of exercise, we'd better exercise every day.

Two misunderstandings of exercise
1, people with high labor intensity don't need to exercise.
Experts say that professional people with high labor intensity should not ignore the exercise in their leisure time because of their high daily activities and consumption. Because there is evidence that only moderate-intensity activities lasting more than 10 minutes have health benefits.
However, it is rare for such people to continue moderate-intensity activities for more than 10 minutes at work, and some even repeat mechanical labor, which requires increasing the level of moderate physical activity outside work.
People in the office need more leisure time to exercise and less sedentary time every day, because they have less activities at work every day. Studies have shown that sedentary behavior for more than 6 hours will significantly increase health risks.
2. Thin people don't need exercise either.
The survey also found an interesting phenomenon. The people with the highest physical activity ratio are not normal thin people, nor obese people, but overweight people. People who exercise regularly have the highest proportion and are overweight.
Experts said that this is a very interesting phenomenon. Maybe obese people lack the perseverance to keep exercising, while normal thin people think they are healthy and don't need exercise. In fact, this is also wrong.
Being thin doesn't mean being healthy, but it's also an unreasonable proportion of body fat and muscle. Studies have shown that increasing exercise and controlling weight can effectively reduce the risk of cardiovascular disease.
Among them, exercise has an independent effect on the risk of cardiovascular disease, and the protective effect of exercise on coronary heart disease and heart failure is stronger than weight control. In other words, exercise is better than no exercise.
