Fortunately none of them , LOL
Your right when it comes to the T boost a nice chick can couse. As a formal trainer myself I once had a colleague who's calves were smaller than my forearms (and no, my forearm aren't brutal), but he knew how to train and motivate clients and was very popular.
Look at charles glass. He was a champ in the 8ties but shrinked a lot after that. He still trains a lot of pro's these days.
Dude, are you comparing fat little sandra to Charles Glass?? I don't think she was a champ in the eighties. Nevertheless, it's ridiculous if a trainer is FAT, if he teaches running, he can be thin as a stick. However, if you want to learn bodybuilding from someone, he should look like he has touched a weight in his life.
But a trainer looking like a barrel??
