Which exercise is most suitable for addressing a low back arch observed during the Overhead Squat assessment?

The Ball Bridge exercise is particularly effective for addressing a low back arch during the Overhead Squat assessment because it targets the muscles associated with pelvic stability and strengthens the gluteal muscles, which are crucial for maintaining proper spinal alignment. By engaging the core and the glutes, the Ball Bridge helps to reinforce the support needed for the lumbar spine, reducing the tendency for excessive arching during movement.

In contrast, deadlifts primarily target the posterior chain and may not specifically correct poor spinal alignment when performed incorrectly. While they can build strength, they might exacerbate existing movement patterns rather than correct them. The bench press focuses on upper body strength and does not engage the core or pelvic muscles effectively to correct low back arching. Wall sits are beneficial for lower body strength but lack the specific focus on engaging the core and stabilizing the pelvis, which is essential for correcting the low back position during squats.

Thus, the inclusion of the Ball Bridge in a corrective exercise program supports the development of key stabilizing muscles while directly addressing the issues observable in the Overhead Squat assessment.
