Lying leg raise
Lie on your back and raise your straight legs up and down.

How to do it
- Lie on your back with your legs straight and your arms by your sides, palms down.
- Press your lower back into the floor.
- Keeping your legs straight, lift them until they point at the ceiling.
- Lower them slowly until they're just above the floor.
Common mistakes
- Lower back arching off the floor as your legs come down. Only lower as far as you can keep it flat.
- Swinging your legs. Lift and lower slowly.
- Pushing hard with your hands. Use them only for balance.
