trans | Gym time

So in a little under a year I'm getting married, and I want to look good in a dress. I'm not thick by any stretch of the imagination, but there is a little toning that can be done around the mid section. And a little exercise is just good anyway, especially during the winter months to help stave off cabin fever, depression, it's goog for you, blah blah blah, etc. etc. etc. So the question is this. Are there any nation gym chains that are trans friendly or any local Nashville gyms that are trans friendly, specifically MtF friendly?
