Sit-up
A classic core exercise where you lift your torso from the floor toward your knees and back down.
Overview
The sit-up is a well-known core exercise. Lying on your back with knees bent and feet flat, you curl and then lift your torso up toward your thighs before lowering back down with control. It moves through a larger range than a crunch, involving the hip flexors as well as the abdominals.
It needs no equipment and is a familiar part of many routines. Moving smoothly and with control, rather than yanking up, keeps the emphasis on the trunk muscles.
The movement
- 1Lie on your back with knees bent and feet flat on the floor.
- 2Cross your arms over your chest or reach toward your knees.
- 3Curl and lift your torso up toward your thighs.
- 4Lower back down to the floor with control.
Beginner notes
- Moving smoothly keeps the emphasis on the abs.
- Crossing the arms over the chest is a simple hand position.
- A crunch is a shorter-range alternative if the full sit-up is tough.
