EDIT: After you do thsoe, study a few things on human anatomy then get some professional models and try to copy them. I usualy just open one in deep exploration with the wireframe on and then have blender open and recreate what is in the other window. After you do those two things back and forth a few times you should have a good idea of how to make a human model with the polygons best suited to the anatomy of the human muscular system, or any clothing items you might have on them. Thats the way I do it...
