The psoas is a two-headed muscle group comprised of the psoas major and the psoas minor. The psoas fuses with a neighboring hip muscle called the iliacus, to form the iliopsoas. All three muscles function to flex the hip, bringing the femur, or thigh bone, in a forward direction. Thus, to stretch these muscles, you need to perform hip extension, a movement that is the opposite of hip flexion. This can be done by bringing the femur in the posterior direction. When stretching the iliopsoas, you will also be stretching the other hip flexor muscles, including the tensor fasciae latae, the sartorius, the pectineus, the adductor longus and the adductor brevis.
