Need some back up on this

[Danger_Dave]

I don't know everything, and I know I don't ^^
What I mean is I know a lot more than when I started, which is what its like for everyone.

That is a very valid point, I go to the gym on Monday or Wedensday, and there is an expert there who goes on these days, so hopefully I'll get a chance to talk to him/others and all will become a bit clearer.

If this is a commercial gym you're going to this so called "expert" likely knows little to nothing.

Here are some key points.
If he doesn't mention compound exercises, squats, and deadlifts, then he's no expert.
