I don't want to be the dick here, but I'd bet a testicle that this is just a mental thing, not a physical thing.
The OP has a fundamental problem -- despite any protests -- with the idea of being a "beginner". Whether he actually is or not is wholly irrelevant. He just doesn't want to be one. And even if you told him that Workout Routine X would get him all kinds of gains, but that it was "for beginners" he'd probably have an issue with it.
Stick to SS. It's good. It will work. We all get you're advanced. That doesn't mean it won't work. And the reality is, what makes you actually an advanced lifter is the realization that you shouldn't give a shit one way or the other. Your will is in a competition with your body to see who can get the best results, and that's all that matters. If you got the will, you'll get the results.
This probably deserves its own post (sticky!) but listening to you guys -- and other friends -- deal with workout routines. How many times have you had a friend on a diet, and they said something entirely nonsensical, that pretty much amounts to "Well, I know decades of medical research says X, but I think I should probably just do X AND Y, since I think that...blah blah blah" and you've had to shake your head and tell them no? Like, ever tell a girl who's trying to lose weight to lift heavy? They'll tell you stuff like, "I don't want to look like a guy!" (like it's that easy to get buff!) or "well, shouldn't I do cardio to slim down, and then lift to tone up?" And you want to strangle them and be like, "Look! THIS is how it works. Not just for 'everyone else' but for YOU TOO! Modern biophysics apply to you as well...SHOCKER!" Well, the reason people are like that is human nature. If people weren't like that, weight loss wouldn't be a multi-billion dollar industry (since weight loss is conceptually about the easiest concept in the world). Or economics...it's simple. You want to not be poor? Spend less money than you make! EASY! But do people get it? No. They argue with you ("well, see, I mean, what's one dinner out? And it's not like I'm doing to notice $100 more debt, I'll pay it off blah blah blah").
People are always making excuses for why something that works, or why a proven concept is somehow not applicable to them. Why? Because a). people don't want to have to face reality, and most "proven" concepts are hard work, and b). because people want to feel special. Plain and simple. They want to think that somehow, the rules don't apply to them because they're smarter than the rule-makers and have figured something out that no one else has.
Stick to SS, just as it's listed.
Or don't, you know? Up to you.
