Sit-ups are a common form of exercise. For those who want to train their abdominal muscles or lose belly fat, they can achieve the effect through sit-ups, and it also has a good weight loss effect. Therefore, many friends will buy automatic sit-up machines. Of course, there are many dangers in using automatic sit-up machines frequently. Let’s take a brief look at it below! Traditional sit-ups require the exerciser to hold the head with both hands and bend the entire upper body close to the knees. However, after research, sports experts pointed out that this exercise method is not only ineffective but also harmful, because while the exerciser uses the abdominal muscles, he is also exercising the hip flexors, which may cause back bending and spinal damage. People with underdeveloped abdominal muscles are particularly prone to injury. The leverage of the hip flexors can also lead to lumbar disc herniation. In addition, exercisers often subconsciously use their hands and hold their heads tightly when lifting their upper bodies, which invisibly increases the chance of cervical spine injury. For these reasons, many branches of the U.S. military no longer use sit-ups to train their soldiers. In addition, sit-ups with legs straight are particularly harmful. According to measurements, this exercise posture will generate 3,300 Newtons of force in the spine, which is highly correlated with low back injuries. Doing sit-ups frequently is quite harmful and can easily bring great adverse effects to our body, so we must pay more attention to these hazards in our daily life. In this way, we can enjoy the health benefits of sit-ups while exercising our bodies. We can try it more often. |
