I'm old and I aint one of the big guys, so take this for what it's worth. I've found that the big muscle groups really benefit using beyond failure techniques, while smaller ones, like biceps, grow the best going to the failure point, but not beyond. With the smaller muscle groups, rest-pause methods keep them growing FOR ME. That might be considered a beyond-failure technique, but with 20'seconds in between, it's a bit different then just hammering away. I do, occasionally, perform forced reps and negatives on biceps, but I don't do it regularly. Besides, I've stopped over-obsessing on arms and am focusing on just being, overall, bigger.
I'm sure marcus will hammer away at me if he disagrees
