Hi Meathead. I only have one lil NPC show under my belt. I used Nolvadex. But the intent is not for fat burning, was my understanding.
If she has her diet 100% dialed in, using cardio and the other things. Then now you just have to trust the process and make it work. You can try to adjust the cardio. Not sure how far out you are talking about.
If you are talking maybe the midsection/abs? Maybe do a waist trainer. But again, it won't get rid of fat.
Has your girl used Vasoburn? I used it, but am questionable on if in fact it gets rid of fat lol. There is some science behind it, but.....LOL.
Good luck, sorry i'm not much help.
