The gluteus maximus muscle does the following:
- Laterally rotates the upper leg.This means that the gluteus maximus muscle rotates the upper leg outward around the axis of the bone (i.e. it rotates the upper leg away from the vertical midline of the body).
- Extends the leg at the hip.This means that the gluteus maximus muscle straightens the hip joint such that there is an increase in the angle between the upper leg and the torso.
"glutes," "butt" - along with gluteus medius.
