What is the primary goal of practicing rib cage arms?

Practicing rib cage arms is primarily focused on increasing awareness of shoulder complex stabilization. This exercise emphasizes the coordination between the rib cage and the shoulders, helping practitioners understand how to engage and stabilize the shoulder girdle while maintaining proper alignment throughout the body.

By focusing on rib cage arms, students learn to connect their upper body movements with the stabilization of the shoulder complex, which contributes to better overall postural alignment and functionality during Pilates exercises. This awareness is crucial for performing a variety of movements safely and effectively, ultimately enhancing strength and control in the upper body.

The other options do not encompass the primary focus of rib cage arms, as they pertain to different aspects of physical performance and do not highlight the specific awareness related to shoulder stabilization that this exercise aims to develop.
