I wasn't going to post on this one but your last post got me.
You should learn your history about bodybuilding before you go dreaming about winning the Olympia. The only Olympia winner taller than 6'0 was Arnold and if he stood next to the current line up his physique while great for its time would look incomplete. Arnold's legs would look like sticks next to Phil, Ramy, Shawn, etc. Arnold would place dead last if he competed anytime in the 90s until now, that's a fact.
Even the classic physique class looks nothing like the golden era, so good luck even getting an IFBB pro card with your way of thinking. Your muscle bellies are still that of a 5'10 guy, 3 more inches won't make you dwarf anyone on any stage, if anything you'd look lankier, narrow and even small when you stand next to 5'6-5'10 guys with the same measurements as you but since they're shorter they'll look wider and more filled out. Plus you're 16 and not on gear and in the gym already with Olympia dreams? lol
