Final answer:
In seated spinal twist, the twist should come from the thoracic region of the spine. It is important to keep the hips stable and initiate the twist from the thoracic region for a proper and effective stretch.

When performing the seated spinal twist, it is important to keep the hips stable and initiate the twist from the thoracic region for a proper and effective stretch.
