No dis, just to note; periods (.) are cool.
So many guy's here on GB make up junk workouts, their accomplishments on lifts, muscle size, who they really are, success in life..etc, etc, etc. Always have sense of doubts, it helps on this site. But I do believe your 34 sets thing now.
If you can't get a massive lat/back pump in 10 or 12 sets, than might want to check what's wrong with the workout plan.
Getting a pump is like having a glass under a water tap, with the water running. Only going to get so much water in that glass, all the other water is just going to run off. Same with a muscle area, only going to get so much blood (pump) into that area before it becomes gorged and no more space for any more blood. Might even find that after many. many sets the muscle area tends to deflate and can get flat a bit. Self defeating, of course.
But if that's what you want to do and believe in the benefits of 34 sets, than that's you business. Just might suggest splitting up the back work and do half of those 34 sets (exercises) in one workout and the other half in the next back workout. Same week or once a week for each back training....whatever.
Good Luck.
