I go by feel. My breasts will hurt a little after a run when my bra needs replacing. Also, when they become so stretched that the tightest hooks aren't tight enough. Depending on how often you are wearing and washing the bra they could last a year, but not much more than that in my experience.
There are no shortcuts. No magic bullets. No secret spells. What works is hard work, dedication, and a daily dose of chocolate.
