<human>: Can you condense the text into a few key points?

She's been getting more physically active and has gotten into a regular routine of yoga. I encourage her in this because I know it's good for her and she is very interested in it. I think she could make a great instructor in a few years time.

But, she's been gradually getting smaller and smaller and when she talks about her fitness goals, I feel a bit disappointed. She's very keen on getting to the point of having a six pack.

I feel like a shallow and perhaps misogynistic piece of shit for thinking this because I know for her it is a health goal and I want to be supportive of that, but I just don't really find the idea of this attractive at all. I have always been very instinctively attracted to women who are less toned. She isn't out of shape right now, she's in fact quite healthy. And it seems like a stupid hang up for me to have. But I can't help it, it's there.

I'm simultaneously worried that I will not be able to be as sexually attracted to her if she does this, and I'm equally worried that I'm being a sexist and shallow piece of shit on the other. Am I wrong to feel this way? Is there a way I can talk to her about this? Has anyone dealt with this before?

I love her to death, and I know this won't be an issue really (at least I hope it wont be) but part of me just can't help but feel grossed out by the idea.
<bot>: GF wants to get a six pack, I find the idea of that sexually unattractive. Can I bring this up somehow or am I a shitty person for feeling this way?
