so the logic here is that someone who doesnt look like he train doesnt know what he's talking about and someone with a lot of muscle do.
the problem with that is that the one with a lot of muscle is probably genetically gifted and/or juiced.
clearly there need to be other ways to figure out ones expertise than just by appearance.
as far as actual tecnique goes, appearance means nothing as we can see from strength coaches, wrestling coaches, boxing coaches, powerlift coaches etc from all around the world.
