The Nordic hamstring curl (NHC) is an exercise in which a person kneels with their feet fixed in position and lowers their body by extending the knee. It reduces hamstring injuries in athletes, and is commonly used as a form of injury prevention. [1] [2] NHC increases strength of the hamstrings and length of the fascia, [3] [4] [5] sprint speed, and change of direction ability. [6] It is debated whether NHC is an open or closed chain exercise. [7] NHC has been compared to the razor hamstring curl. [5] [4]
