When performing a supine leg raise what muscle is the prime mover?

The prime mover in the supine leg raise is the iliopsoas. The iliopsoas, commonly known as the hip flexor, is actually comprised of two muscles, the iliacus and the psoas major. The rectus femoris is a synergist for the exercise.

The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors). Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.

Similarly, why is the supine leg lift contraindicated? The proper contraction of the abdominals in the supine position will cause a posterior pelvic tilt as the pelvis rotates toward the sternum.
