Work on the Iliacus in Session 5
The iliacus (pronounced ill-eye-a-cus) is another muscle you probably have never heard of. It is the sister muscle to the psoas (from the previous photo), and they join together to attach on the inner thigh. Because they merge so completely that you can't tell them apart, sometimes they are together called iliopsoas (ill-ee-oh-so-as). The iliacus is like a big fan, attaching all along the inside edge of the hip bone. It can be easily reached, and I often use my elbow for this work since it provides a broad, stable contact that is sometimes more comfortable than fingertips.
