My wife has been working out a lot. How do I tell her she is to muscular for my liking now?

This is a bit embarrassing to admit to. My wife has been working out lately and has gained a lot of muscles. She is weight training and now has muscles in places I never even knew it was possible. My issue is that even though she looks very good, her muscular physique doesn't really turn me on.<br><br>I'm not a 100% sure on why that is, but I just can't seem to like it when women have too many muscles. My wife knows that I prefer women with average body so I think she'll be upset if I tell her to stop weight training. How do I approach this?
