I am struggling to understand how people pre-determine their desired rep counts for each set of a training session.
I don't know about everyone else, but if I walk into the gym and hop up on the pull-up bar, I might be able to crank out 8 chins over the bar from a dead hang... on the first set.
That doesn't mean that every other time I jump up there, I will be able to do 8. Maybe I will do 4 or 5.
If people are lifting to the rep count as their failure point, then how are they not getting diminishing returns during the same session for subsequent sets?
I see this type of definite-rep-count training plan far too commonly for it to be something that only a small group of people can do reliably. Can anyone shed some light on this? What am I missing?
