I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.
Your feet wedged under the pads with your torso in the void and your hands next to each ear :
Inhale and raise your torso to try to touch your knees with your head rounding your spine.
Exhale at the end of the movement.
This exercise is excellent for working rectus abdominis and a little bit your obliques. It’s good to know that during anteversion of your pelvis, iliopsoas, rectus femoris and tensor fasciae latae are strongly solicited.
This movement requires good power in abs. It’s necessary to do exercise easier before to gain this power.
