What is a suggested assist for the long sitting positions, particularly in arm sitting series?

Using a wedge under the sitting bones in long sitting positions can enhance alignment and provide proper support for the pelvis. This assist is particularly beneficial because it helps elevate the hips slightly above the knees, promoting optimal spinal posture and reducing the risk of slumping. This elevation allows for a more effective engagement of the back muscles and encourages a more neutral spine without excessive strain.

In the context of the arm sitting series, maintaining a correct alignment is crucial for effective movement and muscle engagement. The wedge assists in achieving this by creating a stable foundation, which is especially important during arm movements that require balance and control.

While cushions might provide comfort, they do not necessarily promote alignment in the same way a wedge does. Similarly, holding a weighted ball or placing the feet flat on the floor may be relevant to other exercises or considerations, but they do not specifically address the alignment and support needed in long sitting positions. Therefore, utilizing a wedge is the most effective assist for maintaining proper posture and enhancing the benefits of the specific exercises performed in this position.
