The seated hamstring stretch is great for increasing range of motion in the muscles of the back of the leg. This is a static stretch, which means that the position is held constant.

First, sit on an exercise mat with your feet together. Extend your arms forward and try to touch the toes. You should feel a stretch in the hamstrings. Hold the stretch for 10 to 30 seconds, then relax. Repeat as needed. Static stretches should never be painful. The general rule is to hold the stretch in a position of mild discomfort.
