We sit on the most powerful and largest muscle in our body, the |gluteus maximus|. It is a thick, fleshy, quadrilateral muscle that forms the major volume of the buttock. The muscle descends downward and outward from its origin and wraps around the outer back corner of the |pelvis|. It connects the ilium, sacrum, and |coccyx| to the |femur| by tissues of the thigh. The |gluteus maximus| consists of coarse |muscle fibers| that powerfully extend (straightens) the thigh at the hip joint and moves it away from the body, as when walking or running. It is also used to raise the body from a sitting position.
