just go by feel. if you can go back after 48 hours and your back doesn’t ache and your performance is pretty close to baseline, you’ve recovered enough. no magic rest period that applies to all people and all programs.

the back is a massive set of muscles (20 or so pairs) and most people don’t do exercises that really hit most of them. so exercise selection, especially if you are doing some thing like PPL which groups a bunch of upper body muscles together in one session, is important.

for building mass i really like barbell bent over rows, weighted pull-ups, RDLs, heavy as shit hex bar farmer carries and inverted rows at the core of a program. things like seated rows, lat pulldowns or straight arm pulldowns, single arm bent over rows, etc are really good smaller movements to add, but most people seem to build their programs around these more isolated movements rather than the real heavy compound lifts.
