Lying Leg Curl exercise (aka. Hamstring Curls) is an excellent isolation exercise to help build and strengthen the hamstrings.

Whether it is used as a warm up before squats or a finishing movement, Lying Leg Curls are a valuable addition to any lower body workout.

Many people suffer from stronger quads than hamstrings, which could lead to knee or low back pain down the road, so this move is an excellent way to fix that strength imbalance.
