We have blue states and red states; I assume we have blue trainers and red trainers. I am curious: do you discuss politics with your clients? Personally, I do. My clients are aware of my political leanings, and we talk about current events, including politics.
No, this usually leads to a discussion that has nothing to do with the training or the clients well being.
No politics, no discussion about religion or on how to raise your children for that matter.
