How to prevent waist injuries when carrying heavy loads?

Because, when using the incorrect bending posture to carry heavy objects, the waist is the main force of the force, and participates in the force. At this time, the pressure on the waist will be unevenly dispersed in the muscles of the disc and the waist, causing one side of the disc to be squeezed and contracted while the other side is forced to stretch. In the long run, it is easy to cause the movement of the nucleus pulposus in the annulus fibrosus, and the spinal nerves are pressed to cause low back pain, which leads to lumbar protrusion. For patients who already have lumbar protrusion, there may be aggravation of lumbar protrusion. Therefore, when carrying heavy objects, you should try to keep the entire spine in a neutral position, use the strength of the legs to move the heavy objects, and do not rely on the strength of the back.
