My coach is a bit unconventional. He is wearing weird clothes. Well, he definitely has his own style. I am happy when I don't have to wear the same clothes during most of the trainings, but occasionally it is not that big issue to put them on.
But please don't ask about my previous coach......
Now regardless of whether you believe the information above or not here is a piece of a story which credibility I vouch for.
Back in my competitive rowing times, during the winters, I would always row on the erg early morning when the gym was empty and nobody was working out yet. Sometimes I would have my own keys to be able to enter on my own. Coach (not the one described here, just a regular human coach) would sometimes come one hour later and would find me there rowing. Lights were always off. He could never understand it and laughing he would say: "I bet you are preparing for 24/7 rowing?". Could he have planted an idea in me back then having repeated it so many times? I guess I liked the lights off more than watching boring square walls.
