I am running the 3-day hypertrophy template with great results, and I plan on jumping right back into it when I finish. In the program, you change between 2 sets of 6 @ rpe 8 and 3 sets of 6 @ rpe 8, which I am guessing has to do with managing training fatigue. My question is, is it reasonable to modify this to change between 3 sets of 6 @ rpe 8 and 4 sets of 6 @ rpe 8 in the second block? My thought process for this is because you discuss increasing work capacity over time, which I may have developed after the first run through of the program, or will this modification lead to too much stress?
This question is more for me to get a better understanding of the training theory.
