When did your weekly strength gains first start to plateau?
Specifically, at what point did you first fail to progressively overload? That is, fail to add either weight or reps to the same routine from week to week?
For context, I'm going on ~18 months of consistent (3-4x/wk) weightlifting. I feel as though I have been stuck on the same weight and reps (8 reps at 85 lbs total) on EZ bar preacher curl for essentially 4 months at this point.
I average 7hrs 15min of sleep/night (track with Whoop), and am consistently hitting my protein goal (>0.7g/lb) at least 5 days/wk.
My question to all of you: When did you first start to experience a plateau in weekly strength gains? How long did that Plateau last? How did you overcome it? is stalling for 3-4 months at the same weight/reps common after ~18 months of lifting?
