Hi Thomas. How the trainer looks would be pretty far down on the list as far as I’m concerned. While I think it’s important that the trainer “practice what he or she preaches,” they need not look like a body-builder in order to be good or know their stuff! As you know, “true fitness,” is a combination of several components and having “the look” (which is most closely aligned with only one of those components) may not be the best way to choose. I’m always reminded of one of the most renowned trainers of heavy weight fighters who himself was pretty slight, and definitely NOT a heavyweight. Yet, it was his MIND, his knowledge that set him apart from others. So, for me, TOPS on my list would be their knowledge, after all how my trainer looks WON’T really help me as a client, but what my trainer KNOWS will!
I hope that this helps.
