The muscle starts from the gluteal aponeurosis and outer surface of the ilium and inserts into the greater trochanter of the femur.
Its main function is to abduct the hip joint, and supports the pelvis when we lift the foot to walk. Weakness in the muscle produces a noticeable limp.
Electro stimulation of the gluteus maximus and medius is extremely useful, and is an area which overlooked. More often than not, more importance is given to quadriceps and abdominal muscle groups.
The gluteus maximus and medius work in conjunction to extend the leg.
