I am going to answer on the assumption that what you want is a general idea of some of the things other fitness people have found enjoyable/inspirational/informative. If that is wrong perhaps you could rephrase the question. Harris is right that that might help.
It looks like you have an interest in wellness and weight control. If you haven’t already read anything by Michael Pollan I think he is both inspirational and informative.
If you are interested in wellness, meditation, and brain science I would recommend Buddah’s Brain. It is not especially scholarly, but very interesting.
You seem to have a certification in both personal training and health coaching? A book I use in my beginner mindfulness class is The Pen and the Bell. It is a great tool for students who like to journal, and find writing a helpful tool for self reflection.
I also was kind of surprised how much I liked Jonathan Urla’s book Yogalates. I think he does a great job of writing about the intersection of these 2 disciplines.
