What is the primary role of the psoas muscle?

Shoulder stabilization

Knee extension

Hip flexion

The psoas muscle plays a critical role in hip flexion, which is the process of bringing the knee toward the chest when moving the leg. It is one of the primary hip flexors, alongside the iliacus muscle. This muscle originates from the lumbar vertebrae and connects to the femur, allowing it to flex the hip joint effectively.

The function of the psoas is particularly important in various activities, such as walking, running, and climbing stairs, where hip flexion is essential for movement. Additionally, strong and flexible psoas muscles contribute to overall core stability and posture. Understanding the role of the psoas muscle can help fitness professionals design effective training programs that improve functionality and performance in their clients.
