To be a little bit fair, really big gymbros don't necessarily know much either. They know how to train for themselves, but when they're at such a high level, they don't necessarily know enough for the level you're at. They probably made a lot of noob mistakes and don't even remember those days. Plus, broscience. It's more like being fat means you can't give good advice while being fit means you could give good advice. I am a little biased because I learned everything I knew getting started from a fit woman.
