I ran 5/3/1 for five cycles, making steady progress in my "calculated maxes" throughout (with normal dips here and there). On the fifth cycle, my 1+ set was getting me around 4 reps only, so I jumped back 3 cycles.
I am repeating a set/rep scheme that I was doing 2-3 months ago, and my reps are LOWER for every given weight on all my + sets. For example, today was week 1 of Deadlifts, 2 months ago I did 365 x 9 reps (on my 5+ set). Today, I struggled to get 365 x 5.
This has been consistent with all my lifts, not hitting the same number of reps as I did a few months ago. So I don't believe it's "Just a bad day".
I'm running FSL x 3 sets, no Joker set, and BBB alternating exercises (OHP + Bench BBB, Deadlift + Squat BBB, Ect.) I even backed off on the number of BBB sets, doing only 4 sets, then down to only 3 sets with no change.
I felt good on my heaviest cycle, not particularly beat up or over trained, so I can't understand why I'm not hitting at least the reps I achieved previously. My diet and sleep hasn't varied.
Any advice, or is it time to re-test 1RM and reset?
