But if folks are instead motivated by measurably climbing strength numbers, then save the complications for when the body won't respond anymore to a stricter diet of simple shit.
Staying simpler longer will probably work better, so long as the program is actually oriented to goals you care about. But doing any program regularly, even if it is adjusted more to retain compliance than to most speedily build performance, is better than nothing at all, or haphazard training.
