Optimization might not be worth the trouble at the individual level, even if that's half the fun for this crowd. But optimization is 100% worth the trouble to make the guidance as effective as possible at the population level. Even slightly better advice can make life slightly better for a zillion people -- think of that in cumulative QALYs or whatever. If it turns out that a certain kind of exercise makes it a little easier for people to reach their health/fitness goals, and it isn't commensurately more likely to injure them, then let us leave no gains on the table.
