The Psoas Muscle’s Important Role

You’re likely familiar with muscles in the body like the gluteus maximus, hamstrings, and biceps. One muscle you may not have heard of is the psoas. Though it may not be as recognizable, it is one of the most important muscles in determining your spine’s health.

The spine is connected to the legs through several muscles, including the piriformis, the gluteus maximus, and the psoas. The psoas is located in the lumbar region of the vertebral column. It attaches to the lumbar vertebrae and also joins with the iliacus muscle to create what’s known as the iliopsoas.

The reason why you’re able to stand and walk upright is because of a curve in the lower spine that bears weight while also transferring the weight above it. The psoas plays a role in creating the curve, pulling the vertebrae in the lumbar area forward and down. The psoas also receives messages from the brain instructing it to move the back leg forward, which results in the alternating between the front and back leg. In other words, every step you take is made possible in part by the psoas muscle.
