Is the hamstring biggest muscle in group?

The gluteus maximus is the largest muscle in the human body. It is located in the buttocks and is responsible for extending the hip joint and rotating the thigh outward. The hamstrings are a group of three muscles that are located on the back of the thigh. They are responsible for flexing the knee joint and extending the hip joint.
