So your rest times between sets is only like 30-45 seconds. That's very brief, almost like pre-contest work for many. Most guys poundages would suffer bigtime on a Mac Daddy exercise like close grip benches, skullcrushers, bb curls, etc resting that briefly. Shit if you're getting the 75's for 6 on db curls after only resting 30-45 seconds, I'm betting you could get the 85's for 6 had you rested 90 seconds. I am far from a volume guy and mostly train HIT - have for years. I'm not one to live in the gym. However, on the flipside, when it comes time for that all-out, bust-ass workset, I want to be able to give it 110% with max weight, hence, I rest long enough to recup so I can do that.
But hey, just like assholes, we all have opinions haha. Arnie vs Mentzer styles, Yates vs Wheeler styles, Coleman vs Jay styles, etc etc. You have found what works for you, so that's all that counts. Good luck on getting those 100's 1 day dude
