This is good to know. I was afraid to fall out of the 6 to 10 rep range on my lifts, but I finally realized I had to let the program run its course. I am now determined to ride it out until I cannot anymore, and I am comfortable with that. I added the pyramid down sets to the triumvirate template (for some extra volume), and I am very pleased with my workouts at this point in time.
I did an entire year of boring but big, and I am working on a few months of triumvirate FYI, so I can only comment on those templates.
The farther along I get into my programming and understanding of the theory behind 5/3/1, the more comfortable I am with trying to improve my training max, and being comfortable knowing that I can hit it at any time (tired, poorly fed, sore, etc.). I think you just have to be patient and realize that you are not training your best ever lifts on this program, rather you are training your training max. For instance, you may come in and get 225 x 10. Next week you may not be able to beat or get that (due to soreness, or being pooly fed, or being tired from work, etc.), but if you set up your weights correctly your training max will go up each cycle and eventually your TM will be 300.
The longer you go without stalling, the better. Just keep reppin like a mofo and addin weight.
Most people I know who struggle with this program don't understand the training max concept, and aren't committed to being patient and making the slow gains. I know I am guilty of that to some degree. I hope I made sense. I am good at fumbling my words sometimes.
