I do have a raw 1RM in the 400’s. I never have a ME bench session that I don’t perform doubles/triples in the >85%. My athletes, whose max bench range from from low 200s (16yo raw) to 738 (21y., bench shirt) also lift at least once per week with reps in the >85% range. Of course they are football players/powerlifters and their goals are different than a sprinter’s.
As far as intensity, I understand that heavier loads bring about greater intensity, but for smaller athletes who are lifting near the limits of their genetic potential, I think all lifts >85% are higher intensity lifts, even if less than 400lbs. Furthermore, I think if Max Strength is what one is looking for, lifting in the >85% range must be included to optimize training towards that end. I also believe that these days should be considered when programming a very CNS intensive program, and may not belong on a Low CNS/Extensive Tempo day. That’s just my opinion, however, and I respect the opinions of those that disagree.
