The iliacus and the psoas make up what is commonly called your "hip flexor." These 2 muscles have an important job, to connect the upper part of your body to the lower half! Although these muscles are also responsible for flexing your hip (bringing it forward), their main job is to help hold your spine, pelvis, and hip together. The iliacus and psoas are called the iliopsoas together. They often time contract and stay knotted up when the body is either too mobile or if those muscles are overused. Because we need them to stabilize us, activities like sitting, running, biking, kicking, and weight lifting are common causes of tightness along with too much stretching like yoga and dance.
As you can see, there are lots of reasons these muscles tighten and this tightness can cause pain in all kinds of places in the body. When you're positioning the hip hook, or the hip flexor release ball, it's really important to find the right spot.
This is a big question that I get.
Let’s get oriented with our pelvic bones. If you put your hands on your hips, do you feel the bony part that sticks out, right inside there is the magic spot we want to release. This and bit lower is the spot we want to start using the hip hook and/ or hip flexor release ball in.
You want to stay away from the middle of your stomach near the belly button. We want to stick around the sides near the inside surface of your pelvis. You can also play around with different angles of the tool. As you're lying on your stomach, use it perpendicular to your body. You can also rotate it and that will help you find spots on the contour of your pelvis.
I hope this helps you to be a little bit more specific on where you're placing your tool. If you have any additional questions, feel free to reach out to me directly. There are lots of reasons these muscles tighten and this tightness can cause pain in all areas of the body.
I uncover these patterns in my bestselling book, Tight Hip Twisted Core - The Key to Unresolved Pain!
This is also why I designed the world's first tool designed specifically to release the iliacus muscle - The Hip Hook
