The BtGB book says to pair push-pull, core-legs and alternating without any rest for basic strength, and I hear that Foundation uses the same modality and is even harder. I have also been told here that for basic strength you should only rest 60-90s between sets, and I suppose this is if you do straight sets and not super sets.
But it has also been said here a lot (I have read a lot of old threads) that when you're doing 3-5 reps or "strength work", you should rest 3-5 min or even more, so these two things are contradictory and conflict with each other.
I just want to understand how can these two mutually exclusive things have been said here about the same exercises.
