This movement mainly trains abs.
Hanging, the raise loads the lower portion of rectus abdominis — provided the pelvis actually tilts. The hip flexors lift the legs; the abs curl the pelvis.
Eight to fifteen reps. Knees bent first, straight once the pelvis tilts without a fight — the other order mostly produces psoas work.
Raising the legs without curling the pelvis. The movement is then pure hip flexion, and the abs only hold position.
