I may be a weirdo, but nowadays I've been doing the following (as far as weight training):
Day 1 Chest and Biceps
Day 2 Legs and Shoulders
Day 3 Triceps and Back
Started doing this after another AM member recommended something similar... Doing this I don't feel like I overtrain anything however I'm not in the gym multiple times a day, just the one 45 mins to an hour session that I can manage.
