Follow-up to: Boring Advice Repository
Many practical problems in instrumental rationality appear to be wide open. Two I've been annoyed by recently are "what should I eat?" and "how should I exercise?" However, some appear to be more or less solved. For example, various mnemonic techniques like memory palaces, along with spaced repetition, seem to more or less solve the problem of memorization.
I would like people to use this thread to post other examples of solved problems in instrumental rationality. I'm pretty sure you all collectively know good examples; there's a comment I can't find from a user who said something like "taking a flattering photograph of yourself is a solved problem," and it's likely that there are other useful examples like this that aren't common knowledge. Err on the side of posting solutions which may not be universal but are still likely to be helpful to many people.

This sounds reasonable. I'm guessing bodybuilding programs are more controversial than Starting Strength. Or is there a clear winner there too?
Thanks for the informative comment.
Starting Strength recommends three sets of five reps at 90% of your maximum lift, each with a few minutes' rest between, as the best programme for building strength. For increasing muscle mass (which is what makes you look good, and is surprisingly not as correlated with strength as it would appear) you want something like six to eight sets of ten to twelve reps, at 60-80% of your maximum lift, with 60-90 seconds rest in between.
Effectively, the more time your muscles spend under load, the larger they will get, assuming your diet provides enough protein a... (read more)
