First and foremost, that was not meant as a shot what so ever. I even addressed that there are endless methods that will get the job done. With that said, what works for one doesn't necessarily work for all and if the young man is working towards becoming stronger, frying the CNS is simply not the best answer for strength, in my opinion. Upper level strength requires an efficient neural system and therefore training purely for hypertrophy shouldn't be the only angle addressed. Obviously it needs to be addressed but not to the detriment of the other half of the equation. I'm also not saying he'll reach a level of overtraining immediately but, as I mentioned, without proper rest and nutrition, it will happen much, much quicker training multiple sets to failure than other methods. Everybody responds differently and has differing opinions. I was simply giving mine.
As for the wide grip issues, I understand you can't load the bar with as much weight in a wide grip, but you can absolutely load it heavy, relatively speaking. In addition, with regards to proper bench mechanics (scaps retracted, depressed) the chest is often less of a limiting factor than the tri's. This is just my experiences with those I have worked with which is why I tend to avoid that particular position. I also work with contact athletes so I have to protect their shoulders a little more than your average gym go-er so, in the end, the reward a bigger pecs simply doesn't out weigh the risk. Lastly, lighten up brother. It's a discussion and most of the time there is so right answer; just tools. Just because I disagree with you doesn't make you wrong or me right. I'm wrong all the time and get called on it everyday at work.
