What common mistake might occur when a client performs single-arm rows?

When performing single-arm rows, a prevalent issue that can arise is excessive spine rotation. This issue happens when an individual twists their torso significantly during the rowing movement, rather than maintaining a stable, neutral spine. Excessive rotation can compromise the effectiveness of the exercise by reducing the engagement of the target muscles, primarily the lats and rhomboids, while also placing undue stress on the spine. Proper form dictates that the movement should be driven primarily by the arm and back muscles, with the torso remaining relatively fixed in position to ensure muscular engagement and prevent injury.

Maintaining a neutral spine and minimizing rotation not only enhances the efficacy of the exercise but also protects against potential strain that could occur from incorrect posture. By focusing on stabilization through the core and limiting unnecessary movement in the upper body, the client will be more successful in targeting the intended muscles and achieving their training goals.
