Guardian I follow the same concept . I always tell people it is not how much you lift it is how you lift it.
I see guys like you mention doing endless lat pull downs. I can watch and see the lats are not even doing the work. I can use half the weight grip the bar and actually pull with the lats , squeeze ,flex contract them and work the lats and feel them pump up and swell.
Sure it hurts the ego at first but fuck it I am trying to be a bodybuilder not a weightlifter.
Bodybuilder = sculpts the body
weightlifter = moves weight
I go through cycles where I do lift alot of weight with a fast explosive motion but that might only be for a few weeks or one excersize during a routine.
People watch me do standing alternate bicep curls and think is strange i do not use alot of weight , 3 seconds during supination up ,squeeze flex 3 seconds down back to prone position per arm a set takes almost 2 minutes 10 reps per arm and by the time I am done with one set ,some nilly head next to me has finished his 3 sets of what i call " bicep upper cuts " bicep curls throwing the weight and using his elbows motion to take the pressure off the biceps . Usually the girls get proper form and tempo's in my gym more then the guys.
I am not the strongest guy at the gym , nor could I care
