Hi Karin. I tend NOT to talk about such controversial (or at least passionate) subjects as politics or religion DURING a client’s session. I am a strong proponent of talking with my client during their sessions, however I try to keep the subject matter light (e.g. a movie they’ve recently seen or book read, or something about fitness etc.). I think that there are certain subjects that are just TOO HEAVY to carry on a conversation about during their workout, but love having these debates with my clients when we are not working out (I think it’s important to sometimes engage our clients in that type of back in forth as a way to show that we as trainers are multi-dimensional and learned beyond just exercise and fitness).
