Why is a large Swiss ball used as the contact point during the early stages of the ball wall push with hip hinge corrective?

In the early stages of the ball wall push with hip hinge corrective exercise, utilizing a large Swiss ball as the contact point is particularly beneficial because it requires less shoulder stability than a smaller ball.

The larger surface area of the Swiss ball distributes the load more effectively and provides greater stability for the user, which is crucial when starting out. Since beginners may not have fully developed shoulder stability or strength, the larger ball serves to reduce the demand on shoulder joint stability. This allows the individual to focus more on mastering the hip hinge movement without being overly challenged by shoulder stabilization requirements.

Using a smaller ball would require a more precise control of the shoulder muscles and may introduce instability that can hinder the learning process of the hip hinge. The larger Swiss ball thus plays a significant role in promoting a safer and more effective learning environment for foundational movements. This helps to ensure that the individual can execute the hip hinge correctly without compromising form or risking injury.
