Is There a Relative Intensity Threshold?

Some people who i find are really volume tracking junkeys, will just become obsessed with hitting a certain volume threshold and not really be exerting themselves hard enough to get much out of it. I think the best measurement for that is for body building training, or if ripertovy training, is repetitions in reserve. In whatever number t is, that's how many reps you could have done if there was a gun to your head and you had to go to failure. So anything shy of fiveup reserve is going to have hypertrophic effects. Thr us going to be vastly lower than anything north of five reps.
