In addition to cooling down, swimming in summer is an exercise that can not only lose weight but also keep fit. But it is impossible to lose weight by swimming once or twice. Go several times a week and have the necessary swimming time every time. Do you think it's better to swim several times a week to lose weight? Let's take a look at fitness knowledge!

1. How many times do you swim to lose weight?

Swimming three or four times a week is the best way to lose weight. After 45 minutes of underwater exercise, body fat will start to burn. If the time is too short, although the body's stress reaction will consume calories, it may be new fat formed by heat, which can't achieve the effect of body shaping. If you are swimming to lose weight, lose weight 3-4 times a week, twice a second time. It's useless if you only use it once a week. In addition, if the body can accept it, it is best to swim for 2 hours at a time. It is reported that swimming for 2-3 hours can reduce weight 1-2 kg.

Second, how long is a tour suitable?

Swimming is a healthy aerobic exercise. When time and physical conditions permit, it should not exceed 2 to 3 hours at a time. Generally speaking, it is recommended to rest for 40 to 60 minutes, and pay attention to rest during this time. Because it will only start to consume body fat after 45 minutes of underwater exercise. Although there was calorie intake before, it was formed by human stress reaction. The time is too short to achieve the effect of shaping. On the contrary, it may be that heat forms new fat and looks fatter. When swimming, the human body's metabolism is very fast, and it can consume 1 100 kilojoules of heat in 30 minutes. This metabolic rate can be maintained for a period of time after leaving water.

Third, what are the precautions?

People will have the phenomenon of "excessive recovery" after exercise. Simply put, in order to adapt to the improvement of the next stage of exercise level, the human body must consume more energy after each exercise than before. This is a self-protection measure of the human body. Therefore, after swimming, people usually eat well and sleep soundly, and their calories are supplemented or even exceeded. Therefore, if you don't pay attention to proper diet, especially stop exercising after a period of time, it is likely to lead to weight exceeding the original level. This is also one of the most important reasons why many people can't lose weight through exercise.
