Equipment
No equipment required.
- Lie on your back with your knees bent and your feet flat on the floor. Rest your fingertips lightly near your temples without pulling on your head.
- Brace your abdomen and curl your upper body toward your thighs, rising partway toward sitting.
- Keep your feet planted and your neck in line with your trunk. Use a controlled range without jerking.
- Lower slowly until your shoulders are close to the floor, then repeat.
Choose a comfortable range and use secure equipment. The illustration is a movement reference; stop if a movement causes pain.
