This machine targets the hamstring. This exercise is a bit easier to set up than the leg extension. The primary concern with this exercise is to make sure that your knees are not resting on the pad. Position your body so that your knees are just riding the edge of the pad. This will place your knee in line with the axis of this machine. As with the leg extension, you want to adjust the lower bar pad so that it does not ride your heel. This will reduce unnecessary strain on the ankles as well.
The leg curl machine is best paired with the leg extension machine. One last note: when performing the leg curl, try to push at least 70% of the weight you use for your leg extension. The greater the separation in strength between the hamstring and the quadriceps, the higher the risk of getting a hamstring pull. ~ Mike
