sit-up
UK: ˈsɪt ʌp | US: ˈsɪt ʌp
n. a physical exercise in which a person lies flat on their back and raises their torso to a sitting position, typically strengthening the abdominal muscles.
The term "sit-up" is a compound noun formed by combining the verb "sit" (from Old English sittan, meaning "to rest on the lower body") and the adverb "up" (from Old English upp, meaning "upward direction"). The word emerged in the early 20th century to describe the exercise motion of sitting upward from a lying position, reflecting its straightforward, action-oriented naming logic.
