I think biggest misconception in modern bodybuilding is this thing called "overtraining". What the fuck is this? Olympic lifters squat to their max every day, 7 days per week, 365 days per year. Yes they're constantly tired, sore and miserable, but this is what it takes to be best in this sport. Back in the day some incredibly impressive physiques were built on very high volume, every bodypart two or three times per week splits. It fucking worked, you can see that on their photos.
Arnold was HUGE. That's it guys, he WAS huge. He had bigger chest and arms than many pros nowadays. Maybe he didn't weight as much BUT he was HUGE.
take a weight you can squat 15 reps with. do sets of 10 with it every day, for a total of 2000 reps per day. maybe 3000 if you're having a good day.
then tell me there's no such thing as overtraining.

do you actually have any idea what you're talking about? olympic lifters are constantly tired, sore and miserable? i don't know any, but i would be absolutely shocked if this were the case.
i've seen top olympic lifting routines. top powerlifting routines. top bodybuilding routines. none of them are that much work compared to what i see people doing EVERY SINGLE DAY in ordinary gyms. most bodybuilders only take a handful of sets to failure... and not even what i would really call failure. yet in my college days i would see people going to failure every set, 12-16+ sets per body part, absolutely grueling workouts. i did it myself. it fucks you up when you look at something written down on a piece of paper and then go off on your own, trying to copy it without understanding the first thing about
how the exercises are actually performed, as so many often do.
