And many of those morons will or have suffered self-caused injury and are primarily focusing on aesthetics and not fitness and getting appropriate results for that. Yes it's possible to just be a meathead. That's not what OP was asking. OP asked for how to find a good routine. Having asked that question myself, I found that were their tons of workout routines out there but that most of them have criticism that makes it very hard to determine what "good" is and a bunch of them are literally injury factories (looking sidelong at shitty CrossFit routines).

You don't have to do 50+ hours of research just to get near a leg press. But if you want to find a good routine it's going to be through a process of self-education, not asking for a YouTube video. If it was that easy, there'd be a very simple pedagogical approach out there that nearly every beginner would use and there isn't such a thing.
