1, Neck Pain: Many friends do sit-ups, and they have no feeling in their abdomen, but their necks hurt. Because when we do sit-ups, we habitually hold our heads in our hands. Because the abdominal muscles have no strength, we forcibly pull our heads up with our hands, which puts too much pressure on the cervical spine, so we will feel pain in our neck. If you do this for a long time, it is easy to cause cervical spondylosis.
2, low back pain: sit-ups hurt the waist, this issue we often say. During sit-ups, the abdominal muscles contract centripetally, while the erector spinae of the back contracts centrifugally as an antagonistic muscle group, so the sit-ups themselves will cause waist pain due to the stimulation to the back. In addition, the abdominal muscles are physiologically responsible for curling the trunk, and when many people do this action, their backs are stiff, straight up and down, and the abdominal muscles are not curled, which will not only make you unable to practice your abdomen, but also make your back ache.
3, spinal injury: in-situ sit-ups will involve gluteal muscles and abdominal muscles, so you need to bow your back, which can easily lead to spinal injury. This risk exists not only in people with poor abdominal muscle strength, but also in people who exercise regularly.
4. Gluteal muscle injury: Modern research shows that sit-ups are only effective for abdominal muscles within 30 degrees when the body starts to lift, so the effective action is to only lift the shoulders and not lift the lower back; If it continues, it will change from abdominal muscle contraction to gluteal muscle contraction. Sit-ups become exercises to test gluteus muscles and spine, rather than just pressing the spine.
Extended data:
The correct way to do sit-ups:
1 First of all, sit-ups lie flat on the ground, keep your body straight and don't lie on your side. Many people do sit-ups sideways, which affects their efforts and makes them tired easily.
2. Secondly, bend your hands and hold your head, so that the strength of your hands can help your head get up more easily. It can also protect the head when landing. Some people like to make fists with their hands on both sides and then get up, which is not only laborious, but also easy to get tired.
3. Furthermore, the feet must be firmly trodden, and the partner must be serious and responsible. When you exercise, you don't have to press, and your strength will be offset.
