It is necessary to ensure a certain exercise intensity to affect the rapid and obvious changes of our muscles and body shape, but for most amateur swimmers, daily exercise is not enough to achieve such training intensity, so even if the body is improved, the effect is minimal. Swimming itself is a good aerobic exercise. But it takes some time to achieve the goal of reducing fat. Generally speaking, it takes more than half an hour. This half hour means that you are swimming, not swimming twice, and soaking in the pool for 10 minutes.
Swimming is not an exercise that can make you lose weight and lose weight immediately. It takes a certain strength to have a certain effect. Swimming has a certain auxiliary function, but it also needs to be combined with diet control and work habits! Requires high swimming speed and has practiced freestyle. I find swimming very helpful in shaping my body. Especially in freestyle, because I need to be streamlined, I also specially strengthened the shoulder opening. Leg press, I feel much higher and straighter now.
Many people swim for a long time, but their bodies are average. Many of them even look paunchy. That's probably because you were out of shape before swimming; It may also be that your swimming exercise has not reached; It may also be because your movements are not in place and you don't get a good stretching effect; Another possibility is that you are "eaten" after swimming and your diet is not good.
