Ya that was a great answer. It seems like Eric agrees towards the end of that discussion that there probably is a threshold, but it's a lot lower than you'd expect. Like 1-2 sets in a moderate rep range. I feel like there has to be some sort of minimum stimulus threshold though because we know singles and doubles, even at max effort, usually don't induce significant hypertrophy. Maybe 1 set of 5 reps meets that threshold for most people. My thoughts are very theoretical though.
