I don't "focus" on maxing out on every exercise. I occasionally will see what I can max out at on the big compounds(onces a month)....bench, squat, deadlift......but on a daily/weekly basis everything is 10-12 for warm up sets and 8-10 for working sets. I'm not all out body building, but I'm not all out strength training. I want to gain size up to a certain level, and also have good strength/lbs. Functional strength is most important.
I have been in the gym long enough to gather a nice arsenal of exercises that I rotate. My workouts are never the same week to week. The only thing that is the similar is the order I hit certain body parts (ex. fly's are always at the end of chest workout) and I typically try and get two "heavy" compound moves in first (uttilizing a couple warm up sets, then 2 working sets). Then I'll do some "lighter", isolation style lifts......this is also when I through in my supersets. A lot of times I even superset some of my cable exercises with ab work that is also done at the cables. The lifting part typically lasts 60-75 mintues. I do 7-10 minutes on the bike before I lift to get the blood flowing and any pre-workout I used kicked good.
As far as shakes.....I think I would eventually like to get rid of them all together. Right now they are working pretty well for me, and with a house situation I have going on I don't see myself being able to really get into cooking and packing enough food to get rid of them. That's why I've tried to limit when I use them. Breakfast on work days, and post workout is my limit right now. Breakfast on the weekend and all other meals i'm keeping whole foods. Next year I would love to get on a routine of cooking up food and portioning it into containers.
