Lie on an incline bench and grip the bars or handles:
Inhale and raise the legs to horizontal, then raise the pelvis, rolling the spine up as if trying to bring the knees to the head.
This exercise first works the iliopsaos, tensor fascia lata, and rectus femoris of the quadriceps when raising the legs. Then it works the abdominal core and contracts mainly the infraumbilical portion of the rectus abdominis when raising the pelvis and rolling up the spine.
