A large number of data and research show that sit-ups do have a certain weight loss effect, but if there is no reasonable and appropriate method, its effect will be very general. The traditional sit-ups are placed behind the head and the index fingers are crossed. In the process of sit-ups, we often raise our heads with the help of our hands, but it is easy to cause neck muscle strain, and correct sit-ups need to fix our feet, which can reduce the role of abdominal muscles. My correct way is to slow down our speed as much as possible, exercise the control ability of abdominal muscles, and pay attention to exhaling from birth. This can also exercise the muscles deeper in the abdomen. Sit-ups are easier than other sports, but they need to be practiced step by step. Otherwise, it is easy to cause muscle strain, which is not conducive to long-term persistence. You can try five times in a group at first, and then practice once each time. When you reach 15 times, you can try to add one more group to achieve the effect of gradual exercise.
Sit-ups are a good exercise. They can lose weight because they can exercise our withered muscles and physical growth, exercise our abdominal muscles and lose our stomachs. But if we want to lose weight, we need to do more than 150 sit-ups every day to burn fat, and sit-ups can also stretch back muscles. Sit-ups can stimulate the peristalsis of our stomach, have a good effect on defecation and dredging the air in the stomach, and can also play a role in losing weight.
