I've heard quite a few varying opinons on this and I was wondering what everyone's take was. In order to gain mass, is your preference working out each bodypart, two times a week, or once(ex. chest monday and thursday and so on. Something like that)? I've wondered for awhile now and while I'm about to revamp my routine (in a week, roughly) I really wanted to take this in to major consideration. I know in order to grow the gospel is train hard, eat hard, rest hard. Well if you had one or two days rest, wouldn't that suffice as long as you weren't still sore when you were about to workout that bodypart again? Just wondering.
