The gluteus maximus is one of the largest muscles located on the outside of the pelvis. Contraction of the gluteus extends and outwardly rotates the femur. When the gluteus are tight it limits forward bending at the hips such as in uttanasana. Like the iliopsoas muscle, the gluteus maximus works unconsciously during standing and walking. Many yoga poses awaken this large muscle including back bends, standing poses and forward bends. The first chakra is the main point of illumination for this muscle along with the sacral spinal nerves. Keeping this muscle strong is paramount in order to keep the pelvis stabilized. The next time you are in chair pose, think about this major muscle and send some loving prana to it. After all, it is responsible for so many of your yoga poses!
