Among all kinds of weight-loss exercises, swimming is the most recommended exercise for everyone. People who swim regularly have good bodies; People who can't swim, soaking in water and having a water fight all have some effects on losing weight. The reasons why swimming is good for losing weight are: 1. Swimming consumes a lot of energy. This is because the resistance of water when swimming is much greater than that of air when moving on land, so it is very difficult to walk in the water, and then swimming will definitely consume more calories. At the same time, the thermal conductivity of water is 24 times higher than that of air, and the water temperature is generally lower than that of air, which is also beneficial to heat dissipation and consumption. So swimming consumes much more energy than running and other land projects, so the effect of losing weight is more obvious. 2. It can avoid sports injuries of lower limbs and waist. When carrying out weight-loss exercise on land, because obese people are heavier, their bodies (especially lower limbs and waist) have to bear great gravity load, which reduces their exercise ability, is easy to fatigue, greatly reduces their interest in weight-loss exercise, and can damage joints and bones of lower limbs. 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. 3. Enjoy the natural massage service: When swimming, the buoyancy, resistance and pressure of water are excellent massages for the human body, and can also beautify the skin. In view of the above reasons, obese people can really take swimming as the main exercise to lose weight. But you must be prepared before swimming and pay attention to safety to prevent accidents. First, we should change our eating habits. Don't sit down or sleep on your stomach immediately after eating. It's best to stand all the time. You can choose to take a walk or organize something. This can not only reduce the accumulation of fat, but also help digestion, because within 30 minutes after eating, if you don't move, it is most likely to form abdominal fat. Then it is necessary to walk and sit correctly. When you walk, you should hold your head high, swing your arms, and always put your arms around your chest. Abdominal muscles do not contribute, so it is easy to stand out. Moreover, walking with swinging arms not only consumes a lot of energy, but also looks particularly energetic. When you sit down, you should also straighten your back, don't bend over, and don't straighten your abdomen, so that you can exercise your abdominal muscles and make them strong and not easy to collapse. Finally, with exercise, shaking hula hoop or doing sit-ups and stretching exercises at any time can gradually eliminate abdominal fat, make abdominal muscles stronger and make it more difficult to accumulate fat. Generally speaking, many slimming creams on the market can only help the body eliminate water after use, but can't really eliminate fat. There are even many slimming creams, in which aminophylline is added. It is said that it can decompose fat cells and make users get immediate results. In fact, up to now, there is no relevant clinical research to prove that aminophylline can decompose fat, so if you want to reduce excess fat, you must improve your diet and lifestyle, which is the way to get rid of it.
