What is the Gluteus Medius?

The gluteus medius is a key muscle on the outer side of your hip, sitting underneath the upper portion of the glutes. If you place your hand on the bony point on the side of your hip and move slightly back and up, you are close to where it works. Its main job is to stabilize your pelvis and control your thigh, especially when you are on one leg, walking, running, climbing stairs, or changing direction.
