Which of the following is NOT one of the ten movement principles in Pilates?

The principle of developing speed is not recognized as one of the ten movement principles in Pilates. Pilates is centered around principles that promote control, awareness, precision, and fluidity in movement, focusing on strengthening the body, enhancing flexibility, and encouraging mindful practice.

The principles emphasize becoming aware of one's body and its movements (awareness), seeking harmony through balance and alignment, and gaining control over both the body's movements and the mind's focus. Developing speed does not align with the core philosophies of Pilates, which prioritize quality of movement over the quickness or rapidity of performing exercises. The focus in Pilates is to engage in slow, deliberate movements to ensure proper form and allow for deeper muscle activation. Thus, speed is not a foundation of the Pilates methodology.
