Which muscle is the main extensor of the hip?

• A. Gluteus Medius
• B. Gluteus Maximus
• C. Gluteus Minimus
• D. Tensor Fasciae Latae

Answer: (B)

Hip extension relies mainly on the gluteus maximus, the largest and most powerful muscle for moving the thigh backward at the hip joint. Its fibers are oriented to pull the femur posteriorly, so when you stand up from sitting, climb stairs, or push off to run, this muscle supplies the majority of the force needed to extend the hip. The other muscles listed mainly perform abduction or flexion: the gluteus medius and minimus stabilize the pelvis and abduct the hip, and the tensor fasciae latae flexes and abducts (assisting with tension in the iliotibial tract). While the hamstrings can extend the hip as well, gluteus maximus provides the primary, powerful extension, especially in functional movements requiring strong hip propulsion.
