It's important to point out hip joint (pelvis-femur joint) is a ball and socket joint and designed to move in all directions. In our modern world where most of it's job is walking and running the muscles around it make the joint work like a hinge joint most of the time. That's the main reason why hip rotation muscles are very weak and undeveloped for most people.
