If she dislikes the music and hates the class, find another one she does like quickly. That's a sure sign for burn out and giving up. I know this personally !!
When something is done in a class that I can't do (knees won't lung or they hurt, etc.) I do squats. I don't care if I'm the only one, at least I'm doing something. I've never seen a class that won't show a modification though. Ask the instructor before class starts. Doing the smallest situps or side reaches will work also.
My biggest concern is that she will lose interest if she isn't enjoying herself. Check into another class if possible.
If you don't love yourself....how can you expect others to.
