I don’t think your body can choose how fatigued it’ll be.
Maybe stressors e.g. training or life stress and not enough fatigue management to make up for it probably pushed you over maximum recoverable volume. Any idea how much work will mess you up the next week?
For example personally I find around about 20-22 weekly working sets in a hypertrophy block, maybe 6-10 reps at 70-80% will do me. I use this info by building up over a couple of weeks and then purposefully exceeding recovery capabilities the last week followed by a deload.
This way I dissipate fatigue for all the previous weeks and am able to recovery properly from my overreach/overtraining week. Coming back in i’m supercompensated /feeling like a god.
