I've been following a chest/tris, back/bis, shoulders/legs, 3 days on, 1 day off, program for a very long time. 4-5 exercises, 4 sets each per "big" muscle groups, 2 exercises, 4 sets each for small muscle groups. Natty. Decent strength/size results but eventually after a few months I hit a wall and start getting injured etc. Haven't dabbled in anabolics so far.
I read somewhere that the important thing for natty lifters is frequency, and also not killing the muscles - doing just enough to stimulate growth and no more.
