Mogwai, let there be no hard feelings among us. Accept my apology if I have offended you.

However, let me just say that
being open-minded as you say, is VERY dangerous. In fact, this is the reason why so many bodybuilders are confused.
Let me use another example, if I may. Let's say you go for surgery and the staff ask the doctor "how much anethesia should we give this patient," and the surgeon replied, "Well, I don't know...let's keep an open mind on this one." What you do? My guess is that you would quickly get off the table and run for your life! This is the reason why there must be a certainty when it comes to exercise science - otherwise, you will WASTE precious, precious time.
Genius, you can't change the laws of nature. And what you are doing is violating them with that type of training. But as far as "buying into it" - you don't have to. Remember, you will be the one that has to deal with his own consequences, not I.
Also, I agree that pushing to failure "every" set WILL require more recovery - But I never said to do that - ONE set is all that is needed. This is what I stated. Why are you doing more sets? Is it better? Why only 3 sets of 10? Why not do more if hypertrophy is the issue? Right?
Note, when you do "a set" you make an inroad into your recovery ability. When you do another set you make a "deeper" in road. Therefore, leaving very little left over for the growth production to occur. So you see, it's counter-productive to continue with this regimine - it's also a waste of time.
In the beggining, you may get away with this volume approach, but eventually your gains will come to a halt. This is why many professionals turn to steroids. This is why "high-intensity training" is so logical.
Let me also add that if everyone is "different" when it comes to training, then why do these authorities advocate the same amount of sets for everyone - the traditional 3 sets of whatever. Where is the logic in this? One set is sufficient - not more, only because you need to do a set to complete a workout.
One must realize that it's really not "one set" if you really analyze it. For example, let's say your doing a set of reverse-grip pulldowns for 10 reps to failure. In essence, there is the "positive" (bringing the weight down) there is the "static" (holding the weight in the contracted position) and there is the "negative" (bringing the weight back to the initial position). So you see, in actuality, you've really done 30 units of work if you don't like the title, "one set."
As far as training to failure, the concept is this: Carrying a set to a point where your forced to utilize 100% of your momentary abilility is the single most important factor increasing size and strength. Working to this "point of failure" when another rep is impossible despite the greatest effort, ensures that you pass through the "break over point."
If you were to pick up a 60 lb barbell and did one rep, would you grow? Of course not. It's the last impossilbe rep (possibly the last one) that will stimulate an increase. Agreed? So, this why you MUST get to that point (as I just mentioned) - not stopping at 10 reps when you can probably do another rep or two.
It is not just I who believe this theory of "one set to failure" but many who have experienced it for themselves. Even professional bodybuilders - Aaron Baker, Dorian Yates, and the late Mike Mentzer to name a few.
I myself, have trained bodybuilders and I've seen the results of my clients by following this simple principle. Last year alone, I performed over a thousand training sessions with clients and they are STILL making progres with their workouts. How many people can say that?
