The buttocks.
The muscles are not normally small in the buttocks. They are required to move the legs which carries all of your body weight. The largest muscle in your buttocks is the gluteus maximus which is one of the strongest muscle in the body. Another major factor in the size of the buttocks is a fatty tissue covering the muscles.
