I have found that to make gains, especially if using additional submax work (FSL, BBB, SSL, etc.) that the TM should be around 85% when starting a 5/3/1 program (not template, an actual program).
These gains include limit strength, but as you know, there are multiple ways to do this (see Bulgarians vs. Russians for a simplified way to look at it). At the end of the day, the TM is widely determined by the actual program you are using, how it relates to all the other aspects of your training and your experience. But in general, 85% seems to work the best for majority of people. Personally, everyone single person I train has a TM less than 85% but I do everything, EVERYTHING off bar speed, never a %. It just works itself out to be no higher than 85%.
We just build and build and only occasionally "out-run" the TM.If you do that, you reset and start again. If you outrun it too quickly, you started way too high or don't program correctly.
(Note: What some of the freshman have done in 2 months is insane - the progress is terrific and NONE OF THEM use any higher than 85%. But it does help when the coach is me and I can do everything in-person.)
Start light - can't stress that enough. It ALWAYS works but greed/ego will kill you.
