I know, I know.."both". I don't have a workout partner and can't always get a good spotter at the gym; I figure there must be others of you in the same situation.
Reading on this site the consensus is that to gain mass you've got to lift heavy. However, we all know that for certain exercises, lifting heavy for 8-10 reps means not being able to use perfect form, ie...rows, curls, etc...
So I guess my question is do you guys stay heavy and use "cheat" reps or not so great form, or do you lighten the load and maybe not go to failure or even close to failure in order to really squeeze the muscle at peak contraction.
I realize this is kind of an ambiguous question.
