Leg curl is a muscular resistance exercise that primarily works which muscle group?

The leg curl is a muscular resistance exercise that primarily works the hamstring muscle group, located at the back of the thigh. The hamstrings consist of three muscles: the biceps femoris, semimembranosus, and semitendinosus. The leg curl exercise specifically targets and strengthens these muscles by isolating and contracting them. While the leg curl machine is commonly used for this exercise, it can also be performed with other variations such as the standing or seated hamstring curl using resistance bands or ankle weights.
