Which prop is used to support the movement of arms from the back in Pilates?

The use of Rib Cage Arms in Pilates is specifically designed to enhance the awareness and movement of the arms while maintaining proper alignment and connection to the back. This prop encourages participants to engage their back muscles and understand how the arms relate to the rib cage during various exercises. By using Rib Cage Arms, practitioners can improve their shoulder stability and mobility, as it promotes a greater range of motion while ensuring that the spine remains aligned. This prop is particularly useful for refining arm movements in exercises that require a strong connection between the upper body and the core.

Other options, while potentially useful in different contexts, do not focus as specifically on the integration of the arms with the back. A sponge ball may be used for various exercises to enhance grip and engagement, dumbbells could add resistance for strength training, and the theraband is often utilized for resistance and stretching. However, none of these props provide the targeted aid for promoting the coordinated movement of the arms from the back in the way that Rib Cage Arms do.
