What are the benefits of sit-ups to the body? What are the disadvantages?

"Sit-ups" is no stranger to us. This is a simple exercise. Its exercise method is flexible, not affected by the weather, and it can be exercised at home for a short time. It is an ideal fitness exercise. In daily life, many people regard it as a daily exercise plan. Doing sit-ups can not only exercise, but also reduce abdominal fat, which is a good choice for dieters. So what are the benefits of insisting on doing sit-ups Every coin has its two sides. What harm will sit-ups bring to our health?

Let's talk about the health benefits of sit-ups.

First, you can exercise the muscles of the waist, abdomen and back to achieve the effect of thin abdomen. During sit-ups, the abdominal muscles exert more force. Long-term exercise is mainly to improve the strength of the abdomen, which can make the muscle groups more hairy. At the same time, it can stretch back muscle ligaments and spine, strengthen back muscle strength, protect back and improve posture, which is one of the effective methods to exercise abdominal muscles and back muscles. Because doing sit-ups can exercise abdominal muscles, make abdominal muscles more solid and powerful, play a barrier role, block fat and internal organs on the omentum, and improve the shape of abdominal sac. Furthermore, when doing sit-ups, you need to consume energy and burn fat, so as to reduce the fat in the abdomen and play the role of thin abdomen.

Second, it is beneficial to gastrointestinal movement and prevents constipation. In the process of sit-ups, it can stimulate gastrointestinal peristalsis, which is beneficial to the discharge of excreta in the body, dredge the air in the stomach and prevent constipation well.

Third, it can prevent bone stiffness. Sit-ups can improve body flexibility and muscle strength. Some studies believe that sit-ups can improve the flexibility and muscle strength of the body. It has been proved that the curvature of the spine helps to deliver nutrients to the intervertebral disc, thus helping to prevent bone stiffness.

Then let's talk about the harm of sit-ups.

First, it may cause cervical spondylosis. Sit-ups will increase the pressure on the cervical spine, because forcibly raising your head will increase the degree of cervical muscle strain, which will easily lead to cervical hyperplasia and cervical spondylosis after a long time.

Second, it may damage gluteal muscles and abdominal muscles. In the process of sit-ups, the movement of the back muscles belongs to centrifugal movement. Sit-ups directly stimulate the muscles of the back, which will cause pain in the back. For abdominal muscles and gluteal muscles, muscle injury is often caused by excessive and excessive contraction, which will cause abdominal pain and gluteal muscle pain.

Third, it may cause lumbar disc herniation. The excessive bending of sit-ups leads to the backward compression of the lumbar intervertebral disc. After a long time, the powerful force will make the lumbar intervertebral disc break through the posterior longitudinal ligament and then squeeze into the spinal canal, causing the compression of the lumbar nerve. Excessive sit-ups may lead to lumbar disc herniation.
