Well, yeah, you're on the same page as me. So say I do 400lbs * 10 reps = 4000lbs total volume for one exercise. I'd consider that low total volume with heavy weights. A bodybuilder might do 200lbs * 40 reps = 8000lbs. At the end of the day, a strength workout (the 1st one) will give the lifter a better 1RM. The bodybuilding workout will give the lifter a better mass gain but probably not the same 1RM as the strength lifter. And by strength, I mean what you do in your last sentence.
