Every time i try to talk to Julie, she says "hm~ i wonder" and the rest of that dialogue. Every time i workout i see the exclamation mark next to her icon, but when i go to speak to her, she just says the same thing again, help?

How often did you workout so far? In my playthrough I had to do the workout what feels like 5 to 10 times after she started responding with only that dialogue.
