During the cable rotation exercise, which position of the hip will help to decrease stress to the low-back?

During the cable rotation exercise, having the hips in a position of hip extension is beneficial for decreasing stress on the low back. When the hips are extended, it helps stabilize the pelvis and maintain a neutral spine position, which is crucial for preventing lower back strain. This positioning allows for better alignment of the vertebral column and reduces the risk of excessive lumbar flexion or rotation that can contribute to injury.

In hip extension, the gluteal muscles are engaged more effectively, offering additional support to the lumbar spine. This engagement allows for a more controlled and stable base from which the upper body can rotate without risking excessive load or shear forces on the lower back, thereby making the exercise safer and more effective.

In contrast, positions like hip flexion may cause the pelvis to tilt forward, potentially increasing stress on the lumbar region during rotation. The positions of hip abduction or adduction also do not provide the same level of spinal support as hip extension, thus not being as effective in reducing stress on the low back during this exercise.
