The role of the gluteus medius during activities such as walking and running is to dynamically stabilize the pelvis in a neutral position during single leg stance. As you can see in the photo below, weakness of the right gluteus medius will cause the left hip to drop when standing on the right limb.
The gluteus medius muscle is located at the outer part of the hip. The gluteus minimus is the smallest of the gluteal muscles and is located immediately beneath the gluteus medius. Together, these muscles work to straighten the hip during activity, stabilize the pelvis and assist with outer movements of the hip.
