A while back, there was a post here in which Sensei Hutch described his preferred weight workouts with higher reps. Today's post describes my preferred lifting workouts with lower reps (and heavier weights).
Neither approach is "right." Different people with different objectives need different approaches. And there are many more variables to a program than simply changing the number of reps. These are only generalizations based on personal preferences.
(I know many people are not interested in lifting heavy weights. But keep in mind that "heavy" is relative. For example, powerlifters would not consider the weights I use "heavy." But I don't hold that against them.)
