Many girls are very concerned about their figure, and some even want to lose weight at the expense of dieting. There are many ways to lose weight. In terms of diet, weight gain can be controlled by eating low-calorie, low-fat, low-salt and low-oil meals. Of course, this effect needs long-term persistence to be well reflected. In addition, in sports, we can also speed up metabolism by running, skipping, yoga and swimming to achieve the goal of losing weight.

Recently swimming has gradually become the first choice for many people to lose weight. This is mainly because people swim in the water, paddle with both arms, kick their legs at the same time, and all the muscles of the whole body participate in sports, which can make the muscles of the whole body get a good exercise. In addition, when swimming, because the density (in other words, resistance) and heat transfer performance of water are greater than that of air (the heat transfer coefficient of water is 26 times greater than that of air, that is, at the same temperature, the human body can dissipate heat in water more than 20 times faster than in air, which can effectively consume heat), so the human body consumes more energy in water than on land. These energy supplies are supplemented by consuming sugar and fat in the body. Regular swimming can gradually remove excess fat from the body without getting fat.

Moreover, swimming has incomparable advantages over other sports. 1. can avoid sports injuries of lower limbs and waist. When exercising on land, obese people are likely to damage the joints and bones of lower limbs because of their overweight. When swimming in water, a considerable part of obese people's weight is borne by the buoyancy of water, which makes their lower limbs and waist much easier and greatly reduces the risk of joint and bone injury. 2. Enjoy a natural massage. When swimming, the buoyancy, resistance and pressure of water is an excellent massage for human body, and it can also beautify the skin. 3. it is suitable for both fat and thin. For thin people, swimming actually makes people fat. This is because swimming exercises muscles and obese people consume excess fat. The fitness effect of swimming is unique.
