I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.
Hook you feet in the gym ladder with your thighs vertically. Your back to the floor and your hands behind your head :
Inhale and raise your torso as high as possible by rounding your spine.
Exhale at the end of the movement.
This exercise mainly works rectus abdominis and a little bit internal and external obliques.
It’s good to know that farther is your torso from the gym ladder and hook your feet lower, this increases the mobility of the pelvis. This allows a greater range of motion and works more flexors muscles of the hips (iliopsoas, rectus femoris and tensor fasciae latae).
