Which muscle flexes the hip?

• A. Gluteus Medius
• B. Gluteus Minimus
• C. Gracilis
• D. Adductor Magnus Posterior Fibers

Answer: (A)

Hip flexion happens when the thigh is brought forward toward the pelvis. The gluteus medius, while best known for abduction and pelvic stabilization, has anterior fibers that pull the femur forward, contributing to hip flexion and slight internal rotation. That front-portion action makes it capable of flexing the hip and explains why it’s the best match among the options. The other muscles here are mainly abductor or extensor/adductor players (gluteus minimus mainly abducts; adductor magnus posterior fibers extend; gracilis is primarily an adductor with some flexion but not as directly linked to hip flexion as the anterior fibers of the gluteus medius). So the gluteus medius best explains hip flexion in this context.
