I understand what you think,because its what you read in the INTERNETZ, but reality is a little bit different. Like I said, you obviously have never done any heavy lifting and your "years" of experience aren't really showing right now.
You clearly dont know the difference between isometric and dynamic, but its ok, this board is not precisely training-smart. Also, Oly lifters, all of them, do direct core work, there is a reason for that, so do strongmen.
Also, you probably, tho I cant be sure, are horminzed to the gills and have barely done any research whatsoever on training because well, thats the beauty of AAS, they do the training for you.
Also number 2, you still havent said anything worth of any value to support your view while I have been using real practical knowledge from sports science, go figure...
Also number 3, FEELING a muscle the day after, whatever the fuck that means has never been a measure of good training, stop with that FEEL THE PUMP-70's crap.
