Think your working on the premise that more is better, which in most cases, it is not. Feel free to spend 3-4 hours in a gym, but that would never suggest that your are training at your most affective level. This in regards to max muscle gains and steady progression in any workout. You can take 3 or 4 exercise, and if performed correctly, will totally produce a very intense workout and excellent results in new muscle mass and advance the strength from workout to workout. And requiring from 45 minute to a little over an hour to accomplish. The time factor can extremely important in a workout geared toward the max effort and results.
Prizm offers excellent insight into training by Olympic lifters, which may transfer to BB'ing movements. Though the exercise selections will be very important and even limited to some body parts. BB'ers in the past, have had success with working out twice a day. A friend in college trained 3 times a day, 3 times a week (squat mornings-bench ,before lunch-BB row after dinner time) for around 4-5 months, and got results. Though it became somewhat on a mental drain after awhile I was told. Did the always valuable 5X5's.
So might take Prizm's good advice and give it a shot. But plan with care, apply logic and curb you enthusiasm (also a great show on HBO). . The CNS will be the key to recovery, from workout to workout, and as you already know, never complete a set to the point of failure.
For max muscle intense training recruitment, I might suggest something along the lines of partial training. The tonnage lifted + time + force/effort , all allowing the most weight lifted at the strongest point of muscle contraction. All with regards to the three phase contraction position of a muscle. Or the three phase (start, middle, finish)set of reps, preformed in a power rack. Both of these methods, I hold in the highest regards for adding power and muscle mass. It's the overload system taken to a higher level. Might suggest "Power Factor Training" by Little & Sisco. Though the book is badly edited, the process is explained very well. The pic's include should inspire any BB'er. Good Luck.
Side Bar: Olympic lifers are the elite athletes of weight training. A PL'er (whom I also have great respect for), is only requires to move a weight a few feet, as opposed to an Olympic lifter who lifts a weight from the floor to arms length overhead..and holds that position.
