Which action is performed by the Hamstrings?

Explanation:
The hamstrings cross the hip joint, so their primary action there is to extend the hip—pulling the thigh backward and decreasing the angle between the pelvis and thigh. This extension is crucial in movements like standing up, climbing, and pushing off during walking. They do flex the knee as well, but at the hip joint their standout role is hip extension, whereas ankle plantarflexion (calf muscles) and hip abduction (gluteal muscles) are performed by different muscle groups.
