What is "hamstring"?

The hamstring is positioned at the back of the thigh, composed of three muscles: the biceps femoris, semitendinosus, and semimembranosus. It plays a vital role in leg movement, allowing for knee flexion and hip extension. This muscle group is actively engaged during activities such as walking, running, and jumping. Moreover, the hamstring provides stability to the knee joint and contributes significantly to leg strength and overall mobility.
