So if I do leg extensions with the stack -305 lbs for 20 reps and do several warmup sets to do that- does that first set of 110 lbs for 20 stimulate anything but blood flow and various metabolic enzymes? Cause it was not nearly as difficult. Certainly I would not grow from that.
yeah but you still performed the sets.
I do 4 sets for bench. first set is strictly to get things going, second two are heavier, to put a load on the muscles and get into the groove of pushing some weight, they are hard but i stop short of back-arching all out effort....last one is all out. I call that the "money set" but it takes the first three to ramp up to it. To me it makes no sense to do two or three sets to absolute failure, I'd rather leave some in the tank for the heaviest set
I have tried one warmup up set and them right into very heavy weight..don't like the way it feels, I'm not "there" yet...and i don't get as many reps as i do when doing two lighter work sets. Everything is firing, i'm amped up and i give max effort.
So call it semantics, i count every set as a set, these guys do basically the same 4 sets and call it one set
