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

The use of Rib Cage Arms in Pilates serves as an effective way to support and guide the movement of arms from the back, facilitating better shoulder and upper back mechanics. This prop encourages proper alignment and helps to enhance the connection between the rib cage and the arms, creating a more integrated movement pattern. By using Rib Cage Arms, practitioners can focus on stabilizing the upper body while allowing the arms to move freely and effectively, which is essential for maintaining posture and balance during various exercises. This support is particularly beneficial in exercises that emphasize upper body engagement, promoting greater awareness of how the shoulders and arms should work together as a unit.

The other options, while they may have their use in Pilates, do not specifically address the intricate relationship between the arms and the back in the same way that Rib Cage Arms do. Each of those props serves different purposes; for instance, a sponge ball may be used for enhancing grip or coordination, dumbbells are typically used for strength training, and a theraband can aid in resistance training but does not specifically focus on the rib cage and arm movement relationship.
