The correct movement that focuses on shoulder mobility is wall angels. This exercise is specifically designed to enhance the range of motion in the shoulder joints, promote stability, and help improve posture. Wall angels involve moving the arms in a controlled manner against a wall while maintaining contact with the wall throughout the movement. This action encourages the scapula to move properly and allows for greater flexibility and mobility in the shoulders.

In contrast, while standing diagonals may engage various muscles and can involve some shoulder movement, it does not primarily target shoulder mobility in the same way as wall angels. Seated rows primarily focus on strengthening the back and shoulder muscles, which is different from mobility. Circuit curls are primarily a bicep-building exercise and do not emphasize shoulder mobility at all. Thus, focusing on wall angels gives a direct benefit to improving shoulder mobility, making it the most suitable choice.
