sit-up
Torso-raising movement
A sit-up is an exercise in which you lie flat on your back, bend your knees, and raise your upper body to a sitting position without using your hands: I do fifty sit-ups every morning.
Sit-ups strengthen the abdominal muscles.
The similar crunch involves a smaller range of motion.
