What Exercise Works the Same Muscles As the Hamstring Curl?
The hamstring curl, or leg curl, is often done on a machine, either lying or seated. You lie on your stomach and place your ankles under a pad. Pull your feet towards your buttocks. For the seated version, start with your legs parallel to the ground and press the weight under you. The hamstrings are the primary movers, but other muscles, mostly those in your lower leg and calf region, assist during the exercise, according to the ExRx website.
