I feel that as one gets older 30's-40's plus, they are much better off using a volume approach and/or pre exhaust techniques, super sets, giant sets, etc, etc.
Yes, some guys are genetic freaks "joint wise" and have indestructable connective tissue and can handle heavy weights/low reps as they age. Most of us however will breakdown and training styles need to be changed.
Look at Palumbo. Only trained very heavy low volume. He's 49 and hasn't trained in 10 years and had full shoulder replacement and his other shoulder is fucked and he looks half crippled. I think we all know that it took it's toll on Ronnie and many others as well. (Dusty H would be an exception here but I don't think he'll be training the way he does no when he's 40+)
Then look at guys like Dexter, Cutler, and many other who trained more volume style. Way healthier for joints in the long run.
Yes, a guy in their 20's should be doing heavy benches, chins, deads, squats, etc to "build the base" especially in the first few years of training but the training style and volume needs to change as the lifter ages. I'm not say train like a pussy but as mentioned above, there are plenty of ways to skin a cat.
