Sit-ups are a very common form of exercise. By doing sit-ups, you can exercise your strength and the strength of your waist. Now many people like sit-ups as an exercise, because sit-ups are simple and convenient. You can do them by lying down anywhere. Doing sit-ups every day can also reduce your big belly. So what parts of your body can be reduced effectively by sit-ups? Sit-ups are a very common form of exercise. The correct way to do sit-ups is as follows: Lie on your back on the mat, bend your knees to about 90 degrees, and place your feet flat on the ground. Do not fix your feet on flat ground (for example, have a companion hold your ankles with their hands), otherwise the thigh and hip flexor muscles will join in the work, reducing the workload of the abdominal muscles. Furthermore, straight-leg sit-ups will increase the burden on the back and easily cause damage to it. The position of your hands should be determined based on the strength of your abdominal muscles, as the closer your hands are to your head, the more strenuous it will be to do sit-ups. Beginners can place their hands on both sides of the body. Once they have adapted or their physical fitness has improved, they can cross their hands in front of their chest. Finally, you can also try crossing your arms behind your head, but each hand should be placed on the shoulder on the opposite side of your body. Never cross your fingers and place them behind your head to avoid straining your neck muscles when exerting force. This will also reduce the workload of your abdominal muscles. It is better to use a slower speed when performing it, just like slow motion playback. As your abdominal muscles pull your body upward, you should exhale, ensuring that all the muscles deeper in the abdomen are working at the same time. After lifting your body 10 to 20 cm off the ground, tighten your abdominal muscles and pause for a moment, then slowly lower your body back to its original position. When your back touches the ground, you can start the next cycle of movement. During sit-ups, the abdominal muscles are only involved in the initial stages of the exercise, after which the hip flexors take over the task. By the same token, turning the body at the end of sit-ups (right elbow touching left knee, left elbow touching right knee, etc.) will not only not help strengthen the abdominal muscles, but may even cause trauma to the lower back due to the pressure caused by the turning. The sit-up exercise has been popular since ancient times. Through sit-ups, the body can be constantly rising and falling, slowly exercising the waist and reducing the belly. It is very effective in slimming the legs, arms and waist. However, you should pay attention to doing sit-ups after meals, as doing sit-ups immediately will harm the stomach and intestines. |
