I've tried every training split under the sun, and the one that works best for me is this one:
Monday:
Chest, Back & Abs....9 sets each, done in compound sets, abs 6 sets
Wednesday:
Shoulders & Arms...7 sets for shoulders, 6 sets each for arms, 5 sets for forearms. Upper arms done in compound sets
Friday:
Legs....9 sets for quads, 6 sets for hamstrings, 6 sets for calves.
All sets done to failure, using a reverse pyramid.
