Ok, on a serious note...
If you have a lat pull machine laying around that also has a pulley system underthe seat; attach a cable from the hook up top, and run a cable from there, down to the bottom pulley. If you have a rowing cable machine, then it's basically the same thing.
Now, what I used to use was a weight belt, but basically you want something that straps around your foot that wont slide off.
Set the weight pretty light, hook in your foot, slide out a bit to give yourself room, and slowly work out that muscle by moving your foot forward and backward. This will help a bit with preventing shin splints, if that is what you are worried about.
