BULLSHIT. Ronnie Coleman and Jay Cutler both use a huge amount of volume. Just watch their training videos. Very few big guys use HIT training.
Aesthetics are gone because bodybuilders are pushing their bodyweights too high. Ronnie and Jay both looked fantastic at 220 lb, and easily could have competed against the champions of the 70's and 80's. The idea that isolation exercises are necessary for a more aesthetic physique is simply laughable. All of the great bodybuilders of the 50's and 60's used freeweight exercises such as bench presses and squats. How do you explain the fact that John Grimek, Dave Draper, Reg Park, Boyer Coe, and Lou Ferrigno all trained extremely heavy on the powerlifts? According to your logic, those guys should have had terrible aesthetics.
Aesthetics is almost entirely a function of genetics. The most aesthetic bodybuilders are naturally well proportioned and symmetrical. END OF STORY.
You are totally missing my point. I know they used (Ferrigno, Coe, etc) power exercises ie; Bench, squats, rows, but they also used exercises to hit each individual bodyparts front lateral, rear laterals, 3-4 exercises for triceps, 3-4 for biceps, etc, when I say 'volume training' I'm talking about 12, 15 or 20 sets per bodypart and 8-12 reps. Bodybuilders way back when rarely if at all did any type of deadlifts. You are right to some extent about the genetics but it is quite possible to also train for aesthetics as well.
Arnold is a great example, he routienly did 20-25 sets for chest when he wasn't supersetting with back and even with his supersets the sets and reps were quite high. Maybe I'm wrong, but I don't see, read or here about people doing even too many supersets anymore exept maybe in the weeks prior to a show.
