This exercise is an advanced version of the standing calf raise and places most of the focus on the upper portion of the calf muscle.
Stand on a small bench or platform, allowing enough room for your heels to hang off the edge. Bend over, and hold on to something stable for support so that your torso is parallel with the ground. Flex your calves, raising yourself up as high as possible before returning to the starting position where your calves are stretched, heels hanging off the edge.
Contract calves at the peak extension of the movement.
Make sure to drop the heel as far as possible to achieve the greatest stretch.
