5 Exercises to Strengthen the PSOAS Muscle

The psoas major is a muscle that wraps around your pelvis from your lower back forward to the lower part of your pelvis at the inner thigh of both legs. More specifically, it originates at the anterior lateral aspect of the lumbar vertebrae LS, joins the iliacus in the pelvis, and inserts at the lesser trochanter of the femur. The iliopsoas is part of a larger muscle group called the hip flexors.

The psoas is active in most of your everyday movement and stationary behavior. It is responsible for bringing the upper thigh toward the torso or bringing the torso toward the thigh, depending on whether your legs or spine is stationary. It also participates in the rotation of the trunk and external rotation of the hip joint.

Some of the daily movements and exercises that involve the psoas: 

• Walking
• Climbing
• Running
• Cycling
• Sit-ups and crunches
