8-9 for chest
6-8 for tri's
9-12 for legs
11 for back (I do singles for deads, so I didn't count them.)
4-6 for bi's
9-11 for shoulders
abs everyday. Couple "sets".
depends on what type of day and what kind of training, but when doing pyramids for Legs I go over. 6 sets for squat, then 4 leg extension and then 4 Stiff legged dead, leg size 26.5, I personally think it is too much but it is great for shock value
Depends on the workout, I change mine all the time but if I am going lower intensity sometimes I will up the volume a bit. As gymtime said if your on, your body can also handle a little more training.
