There can be “general rules of thumb,” but they are just that, and shouldn’t be taken to be the be-all-end-all of creating a training protocol that will yield the best results for everyone. Some people respond better to high reps than low reps, some people are prone to injury if they go too heavy, some people have certain exercises that aggravate old injuries or certain body parts, some people have schedules that make certain protocols work better (and more sustainable) than others (how many times per week, how long each session, etc). There’s also the question of what equipment you have, if you consistently have reliable spotters, etc. Then, since you mentioned “while on aas,” that throws another variable(s) into the equation. There’s some basic level of trial and error in finding what protocol works best for you, that is what yields the best results and you enjoy doing.
