What is the Obturator Internus?
The obturator internus is a deep muscle in your hip. It sits inside the pelvis, lining part of the inner wall, and its tendon travels out through a small opening to attach near the top of your thigh bone (femur). Because it is buried under larger muscles, you will not see it from the outside, but it plays a big role in how your hips feel and move during training.
