No, I see no reason why I should not post something that was sent privately if he did not receive any assurances from me that it would remain private.
Because I love trolls, they're so much fun! I get a huge amount of enjoyment at how long trolls can keep their cover. This guy wasn't particularly good (too much at once), but some of them are absolutely amazing.
If he were a troll, why do you think he would send you a fairly coherent private message?
And a troll with 3 posts posting under a real name abbreviation isn't much of a troll. Is it possible that he isn't a troll, but that everyone on this forum jumped on him with the follow the leader mentality that it seems is typical, scaring away potentially good members? oh well.
If you squat 245lbs and are hitting a plateau, then something is seriously wrong. You shouldn't have to do anything fancy to make progress, the simplest programming, sticking to the basics is all you need.
Lucky, that's what this whole "starting strength" thingo is known for - the basics.
I suggest "Starting Strength." You may think you are familiar with basic strength training, but reading this book will at least confirm it and be a useful reference. It will more likely teach you quite a bit. And I don't mean that as a dig on your knowledge level. It is a good book.
The general consensus in here is that you don't really need to work 'core' if you have a basic strength program going. Not sure why people are being such dicks to you, but it might be that your post is fairly naive to the way most of us train.
