How to do it

- 1
Sit on the floor with your legs extended in front of you and your hands placed slightly behind your hips for support.
- 2
Lean back slightly and engage your core muscles.
- 3
Lift your legs off the floor, keeping them straight, to a height that challenges you while allowing you to maintain good form.

Expert tip
Keep your lower back pressed against the floor to prevent strain and ensure your abs are doing the work.
