Like I said before I know so many successful bodybuilders who train like that. Many pros go to the gym and use the weight they feel they are up to that day. If they were following a script they would bang their head against the wall to get one more rep from last week's journal entry. I am guilty of being a journal anal junkie during training. When in a cycle I always try to beat last weeks entries and this leads to quick burn out.
I used to do that,in fact,between you and I we`ve more than likely done everything there is to do in this game,but these days,I work with a weight that is out of my comfort zone n heavier sets,actually there is nevrer a comfort zone,but I don`t care about getting one more rep than last week,unless of course I can............I always listen to my bodys feedback and train accordingly.
If I feel strong on any given day,I go heavier,but regardless,I always go as heavy as I can for the amount of reps I`m shooting for, or as heavy as I can for the training protocol I`m using at any particular time.
I throw in a lot of intensity techniques and do certain things form wise to ensure I`m hitting the target muscle properly, which at times will limit my poundages,but is more effective for muscle building, which is my goal as opposed to just getting stronger.
At 58,I`m always stronger than the average slob on the street, and still, pound for pound, as strong as most guys in my gym if not stronger,but I don`t train for strength anymore at all.
