Many people don't master the correct methods in the process of fitness, and some fitness actions are easy to cause physical injury, especially twisting sit-ups, which are easy to affect. Many people usually do sit-ups to exercise the mermaid line.

In the process of sit-ups, many people also exercise by twisting sit-ups. Local muscle lines are easily formed in the process of twisting sit-ups. Because of the large torsion, it may lead to local muscle traction injury, so the possibility of injury will be higher.

Step 2 bend down and pull hard

Some exercises seem simple, but fatal injuries may occur. Especially when bending down and pulling hard, it may cause damage to the lumbar spine. In the process of fitness, many people do what they can, and often lift weights to exercise their arm muscles. In the process of bending down to lift heavy objects, if the weight of heavy objects exceeds the range that the body can bear, the lumbar spine is very vulnerable to injury in the process of bending down and pulling hard. Careless will damage the lumbar spine, and even cause joint damage.

Therefore, in the process of fitness, we must pay attention to the correctness of the method, and at the same time do what we can, and don't do physical exercise that exceeds the physical load to prevent health damage.
