I share the same thoughts as Proffesor X. Many thick men started out and got to being thick by lifting weights but later in their lifting careers, turned to lighter weights and higher reps. Nasser El Sonbaty is an example of this. But then again, he tapped out his genetic peak in his later career as an IFBB pro.
I have the same observations as Dante Trudel. The most top BBers, the freak massive ones, move some serious weight and eat like bears. We are talking about Gary Strydom, Mike Matarazzo, Dorian Yates, Greg Kovacs (didn’t have stellar aesthetics but was big as a house), Chris Duffy, Michael Francois, and Phil Hernon.
These guys really moved weights and were always looking to add more weight to the bar. Then you have people like Flex Wheeler and Shawn Ray, whose physiques stayed the same for years, guys that didn’t really chase the weights and ate the same diet for years.
I have seen Flex Wheeler train in videos and I thought it was a joke. The guy handled weights I could handle with no problem and was either joking and giggling between sets or looked like he was half asleep. If I remember correctly, I think he was once doing seated forward lateral raises with 15 lbers in one of his videos.
Then again, some guys do really grow off of higher reps. Dave Tate said he grew best off of sets of 10 - 15 reps.
Like Proffesor, I too have more warmup sets now in my lifting schedule simply because I move more weight on my working sets now. There is no way I am touching any exercise with >315 without at least 3 to 4 warmup sets. I usually do 3 warmups sets for the first big exercise of a session.
Yes, there are people who have different needs who do not require intensity with >70% of the max for their circumstance. But I thought we were just talking about healthy bodybuilders here, not people being physically rehabilitated to simply function like a normal human being.
