people always say that the best rep range for muscle growth is 8-12 per set. but how can I do it? from what I see and I do, I find out that, for one exercise, I can do 3-4 reps non-stop, then I breath for a few seconds (just a few seconds, like 5-6 seconds), I can finish 1-2 more, then a few seconds breathe again, I can do 2 more which I totally finished the "8 reps", does this way count as 8 reps per set? or should I lower weight to finish 8 reps without breaking?
Thank you for any opinion.
