The single-arm cable row is particularly effective in addressing restricted range of motion in the upper back musculature because it focuses on unilateral movement, which allows for a greater stretch and strengthening of the back muscles. This exercise targets the latissimus dorsi, rhomboids, and trapezius, which are crucial for improving mobility in the thoracic spine. By using a cable, this exercise also promotes dynamic movement, engaging the stabilizing muscles and enhancing overall back function.

In addition, single-arm cable rows allow for a wide range of motion, which can help to alleviate stiffness and improve flexibility in the upper back. Performing this exercise can create better mind-muscle connection, allowing individuals to consciously engage and strengthen often underused muscles in the upper back, thus contributing to improved posture and increased range of motion over time.

Other options may target different muscle groups or not provide the same level of focused engagement needed for upper back mobility. For instance, the seated shoulder press primarily works on the shoulders and may not specifically address upper back tightness. Barbell deadlifts focus on posterior chain development, while chest presses engage the chest and shoulders more than the upper back. Therefore, the single-arm cable row is the most appropriate choice for improving range of motion
