I have a question which somewhat relates to RPE use. I’ve heard Jordan say before that acute performance on the gym doesn’t really matter, so for example if you have to work out 4 days in a row, and your lifts suffer on the 4th day it’s not really a big deal and the goal should be to just get the volume in. I’ve also heard that one of the benefits of RPE is that while you can mitigate bad days, you can also take advantage of bad days. So for example if you’re 1 @ 8 on squats is 200kg, a bad day might net you a 195kg squat but maybe a good day gets you to 205kg. My question is this: if acute performance in the gym is not a big deal, does taking advantage of that “good day” really matter in the long run?
You want to apply the appropriate training stimulus based on your level of performance potential on a given day. While there is a range of appropriate training stimuli that will work for a given goal, the further you get away from this, the worse your results are likely to be.
