smokepole- agreed; I'm only strength training twice a week (and not overly crazy when I do). I do get a fair bit of running/hiking in during a typical week, but outside of races and an occasional intense training session (usually hill repeats), they are usually on the gentler side.
I've found with age- that consistency with lower intensity is more productive (with lower incidences of injury) than higher intensity and less consistency; of course there are variances with different folks
