My personal appearance hardly resembles that of the portrayed personal trainers, and I neither shout nor scream at my clients. I remember once being introduced by one of my clients to her friend, and it was quite obvious that this friend had the TV image of a personal trainer in mind. Upon noticing that, my client said: “Who did you expect me to train with? Attila the Hun?”
TV is all about ratings, the more outrageous the behaviour the better. It is even demonstrated in debates, and it seems that any form of civilized discourse is looked upon as weakness. Where would this world come to if we let the other person finish a sentence !?!?
