Hamstrings
the agonist muscle or prime mover is the gluteus maximus in hip extention and in hip flexion the hip flexors is the agonist muscle.
Vastus medialis, vastus intermedius, vastus lateralis, rectus femoris. Together, they are the quadriceps femoris.
Biceps Femoris and Semitendinosus muscles of hamstrings
hip flexion and hip extention
The prim mover for hip flexion is the Rectus femoris. This is a quadricep muscle that crosses the hip joint.
The flexor carpi radialis is the agonist muscle in wrist flexion. This muscle, know as a wrist flexor, is located in the forearm.
Function of the sartorius is flexion of the hip and knee joints. It is also called as 'Tailor's muscle'.
the tensia fascia muscle does abduction, medial rotation and flexion of the hip joint
Technically speaking it's the abs. The agonist muscle in a situp is actually the hip flexors.

balance
The rectus femoris THe regular Muscle Action is hip flexion with knee extension, as in kicking a ball or doing a straight leg raise The reverse muscle action is still hip flexion with knee extension, but as in doing sit-ups while lying supine with knes straight ahead
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
Vertebral Foraminal Entrapment on Hip Flexion and Knee Extension
a prime mover is the main muscle that causes movement. In the case of the hip flexion, the prime mover would be the rectus femoris or the ilopsoas
