Examples are the Quadricep and the Hamstring, or the Bicep and the Tricep. Without the pair muscle, once an action was carried out, there would be no way to undo it.
Your thigh muscle is called your Quadricep.

The hamstring muscle group (biceps femoris, semitendonosis, semimembranosis) are the antagonists to the quadricep group.
Rectus femoris and the three vasti
Quadriceps weigh about 90 pounds. What? Are you kidding? Where did you get this information? Shame on you for misleading readers in this manner.
False. The quadriceps muscle is primarily responsible for extending the knee, not flexing it. The muscles that flex the knee are mainly the hamstrings.
The prim mover for hip flexion is the Rectus femoris. This is a quadricep muscle that crosses the hip joint.
In Latin quadriceps means four heads, and the quadriceps femoris muscle has four parts called heads.
