These muscles (the obdurator internus and externus, the gemellus superior and inferior, the quadratus

It does hip flexion, hip abduction, internal rotation, and it even internally rotates the lower leg through its attachment to the IT band.       Because the TFL has so many abilities, it is often overworked. It’s just so easy for other muscles to lay back and let the TFL take over. The TFL is also
