Very good post Eric.

And i agree with most of it except "There is no reason that three sets of 8 or so is better than 5 sets of 5 or 4 sets of 6 for that matter."

Why do 8 reps when <6 reps, when the heaviest loads are used, effectively stimulate all fiber types there are to stimulate?

Also, why do high sets when muscle growth can be very adequately stimulated with relatively few sets if each workout set is performed to the point of muscle failure?

Does these not quailify as reasons?
