Hamstring

The three posterior muscles of the thigh are the biceps femoris, the semitendinosus, and the semimembranosus. The hamstrings bend the knee and stretch the hip. Strong hamstrings contribute to strong pedal strokes, fluid running, and injury prevention for endurance sports. Weak or stiff hamstrings lead to strains, lower back pain, and imbalance. Hamstring curls, Nordic curls, and dynamic stretching are exercises done by athletes to strengthen and stretch the hamstrings. These strengthen them and reduce the likelihood of suffering from overuse injuries.
