Which precaution must be taken during the Prone Row to prevent back issues?

Preventing back issues during the Prone Row exercise is crucial for maintaining proper alignment and reducing the risk of injury. Overarching of the back can lead to excessive strain on the spine and surrounding muscles, resulting in discomfort or injury. Keeping a neutral spine position ensures that the back remains aligned and reduces excessive stress during the movement.

In this exercise, the emphasis should be on engaging the core and maintaining a stable body position to support the lower back. This helps to distribute the load appropriately and ensures that the exercise is targeting the intended muscle groups effectively without compromising posture.

The other options, while they may seem like potential concerns, do not directly address the critical aspect of maintaining spinal alignment during the exercise.
