It is important to perform a posterior pelvic tilt prior to performing the crunch. To do this, press your lower back into the floor while curling your pelvis slightly upward. This will engage your abdominal muscles from the start and make the movement more efficient. Place your hands across your chest or down at your sides rather than behind your head.
