So, I’m in the third week of my first cycle of BBB. I’ve been running it 5/3/1 (percentage and rep scheme) and I think I’d like to switch over to the 5s Pro rep scheme, still running the 5/3/1 percentage programming. I understand that instead of 90%1RM TM, with the 5’s Pro, I should be starting with 85%. I was reading a thread on here from last year where Jim replied to someone’s question similar to mine, citing that this person should start with 85% for all 4 lifts, then adjust as necessary. He said maybe for one or all lifts, they would end up dialing down to 80%, or maybe even ramping up to 90%. What was not present in the dialogue however, was what exactly would this person be looking for to determine if he needed to go up or down, or stay at 85%.
So, how will I know if 85% is my sweet spot? Should I I be looking for my final week three final set to be more or less almost to failure at 5 reps? I know Jim is big on bar speed, so I’m trying to figure this out in my head as to what exactly I’m looking for.
