Which muscle assists in both hip flexion and adduction?

The pectineus muscle is an important muscle in the hip region that plays a dual role in both hip flexion and adduction. This muscle is located near the top of the inner thigh and originates from the superior pubic ramus. Its fibers run downward and laterally to insert into the proximal femur.

When contracting, the pectineus helps to flex the hip joint, bringing the thigh forward and upward, while also assisting in adducting the leg, which means bringing it closer to the midline of the body. This dual function makes the pectineus particularly valuable for movements requiring stabilization and coordination in activities such as walking, running, or performing complex exercises in Pilates.

In contrast, while the other muscles listed may have roles in hip movement, they do not equally contribute to both hip flexion and adduction to the same extent as the pectineus. For example, the psoas primarily focuses on hip flexion, and while the sartorius also assists in hip flexion and can produce some abduction, it does not effectively adduct the hip. The tensor fascia latae is mainly involved in hip abduction and stabilization of the pelvis rather than adduction. Thus, the pectineus
