Combined with cardio, diet, etc, you are losing fat as a result of these body bar exercises, which helps bring the muscle to view. Muscle tone is simply what allows your muscles to move, and tone has to be balanced throughout your body in order to move. If you really wanted to increase the "tone" of those muscles you would have to increase the muscle fibers in them--ultimately making them bigger, stronger, not sleeker or 'toned'. Your body may end up looking sleeker, but that is because you lost fat, not because you are "toning".
