I full body wash/scrub + shampoo my hair every other day.
In the days between, I just rinse off my hair thoroughly, and put a little gel soap on my hands into a lather and rub into my groin, pits, and buttle. If any lather is left I get it between my toes simply because I walk a lot at work and don't want any fungus.
I do NOT scrub on those off days, or else my skin will over exfoliate and get dry. Exfoliation is good, yes, but it's been widely exaggerated to sell products we don't need.
ADDITIONAL PSA: Wash behind your ears folks. Believe it or not, it can get smelly back there if you don't give it enough attention depending on the shape of your ears and the way the skin folds back there.
