For fighting, strong abdominal muscles are not only beautiful in appearance, but also can greatly enhance the strength of waist and abdomen, thus making the overall action more powerful and increasing the fighting ability of abdomen. Therefore, all fighters have strong abdominal muscles. Although some people are not obvious because they are fat, it does not mean that their abdominal muscles are not strong.

Sit-ups are the most traditional exercise to exercise abdominal muscles, but in recent years, the fitness community has found that this is not the most effective action to exercise abdominal muscles, because the crotch muscles of sit-ups will share most of the load, and the load that really falls on abdominal muscles is not large, but sit-ups are the most effective action to concentrate the load on abdominal muscles. After training and practice, it is much stronger than sit-ups to stimulate abdominal muscles, so we recommended this project to you a long time ago, but many friends still responded.

Let's talk about sit-ups:

Sit-ups lie flat on the ground with your feet bent, and then the whole upper body sits up from a flat position. In fact, it is not the abdominal muscles that pull the body up hard, but the iliopsoas muscles in the crotch. The role of abdominal muscles is to keep the upper body upright, so that the upper body can sit up straight under the action of iliopsoas muscles. Although power is also used, it is not the main source of power. Therefore, many people do sit-ups, and they don't feel pain in their abdominal muscles, but in their legs and crotch.

Let's look at the supine abdomen:

Lying flat posture is the same as sit-ups, but the difference is that the lower back is always close to the ground and the upper body is bent upward during the whole movement, which can obviously feel the feeling of abdominal muscles being squeezed. After the upper body bends to the limit, pause for a second or two to resume the lying posture, and so on. The whole movement is completely driven by the contraction and extension of abdominal muscles, so it is really important to focus on abdominal muscles. Let's summarize the essentials of sit-ups and sit-ups in two sentences for your reference: sit-ups are touching your legs with your chest. Lying on your back and rolling your abdomen is thinking about touching your abdomen with your forehead (although you can't get it). Lying on your back and abdomen are excellent exercises to stimulate abdominal muscles. After the exercise, you will feel very sore in your abdominal muscles. Pay attention to doing back in situ after each group of exercises and stretching abdominal muscles to avoid muscle stiffness due to insufficient relaxation.
