I think people get high intensity and heavy weight low reps confused. A set taken to absolute failure is high intensity. A set of 5 reps in the bench press to failure is hard a set of 15 to failure is harder. Arnold would do multiple sets to failure Mike would do one. I like Arnolds frequency and mikes one set to failure. I like using heavier weight lower reps on compound movements and a moderate weight higher reps on isolation movements.
