sit up
Torso-raising repetition
Sit up describes the motion of rising from a lying position to a seated one: The patient struggled to sit up in bed.
To sit up is also to stay awake past one's usual bedtime: We sat up talking until 3 a.m.
When something makes you sit up and take notice, it commands sudden attention.
A sit-up is the abdominal exercise of repeatedly raising your torso from a supine position.
