Has she gotten any visible results since that thread last summer?
What kind of shape is she currently in, honestly? If she's already lean/skinny/whatever, "toning" translates to "building muscle". If she's on the curvier side, "toning" becomes "fat loss".
For the first case, you could consider this:
But her nutrition, particularly getting plenty of protein and calories everyday, will be key to building muscle.
For the second case, a full body or upper/lower split is going to be the most efficient path to that goal. If she doesn't want to do that, that's on her and all you can do is provide the info for her to either accept or ignore. And again, nutrition will be key here - enough protein and enough calories - not too many and not too few (dropping calories too much/too fast is a problem some ladies do fall into).
