Situp → It is formed from "sit" (from Old English "sittan", meaning to be in a position of rest) and "up" (meaning to a higher position). The word "situp" refers to the action of moving from a sitting position to a more upright position, typically used in exercise contexts.
Think of the action of being in a resting position ('sit') and then moving to a higher position ('up') — that's what a situp involves.
