What is the correct way to perform the "Short Spine" exercise on the Reformer?

The "Short Spine" exercise on the Reformer is designed to articulate the spine while engaging the core muscles and promoting flexibility and strength. The correct performance of this exercise involves lying on the carriage, engaging the core, and rolling the spine sequentially, allowing for a smooth and controlled movement. This promotes spinal mobility and helps create awareness of alignment as the spine moves through flexion and extension.

The engagement of the core is crucial in this exercise, as it helps stabilize the pelvis and prevent strain on the lower back during the rolling motion. Sequential rolling means that each vertebra moves individually, promoting joint flexibility and strength as well as enhancing coordination.

While other positions mentioned, such as lying on the side or stomach, might involve different muscle engagements, they do not accurately represent the technique and objectives of the Short Spine exercise. Additionally, keeping the legs stationary does not incorporate the necessary movement through the spine that is essential to executing this exercise effectively.
