What flixators muscles are used in hip extention?

The primary flexor muscles involved in hip extension are the gluteus maximus, which is the largest muscle in the buttocks, and the hamstrings, which include the biceps femoris, semitendinosus, and semimembranosus. These muscles work together to extend the hip joint, particularly during activities such as standing up, walking, and running. Additional support may come from the adductor magnus, particularly its hamstring part.
