Technique
- Knees bent, feet flat, hands on the thighs or crossed on the chest.
- Curl the trunk, lifting the shoulder blades, exhale at the top.
- Lower slowly without dropping to the floor.
Common mistakes
- Pulling the head with the hands.
- Lower back lifting off: that is a sit-up, not a crunch.
