Bench is jumpy
The huge dip in bench is what an injury plots to. Otherwise it was this:
How often did you have to break thru a psycological barrier because you were lifting/pushing/pulling something that seemed beyond your wildest capabilities?
(I'm trying to build my excuse case after seeing your solid progres here)
All three lifts required breaking through a barrier. In each case it was not what I thought I could do, since I tend to think I ought to be totalling 2000+, it was more the shock and fear of being under a very heavy weight that would cause me to fold up.
For deadlift, the answer it was volume trap bar deads. Finishing the last reps when I just wanted to quit is when I realized I could pull a lot more if, quite literally, I just tried harder. That mental magic made all three big jumps on deadlift on the graph.
On squat it was terrible. I had not done this plot yet, but I looked at the numbers are realized I just wasn't getting anywhere. My trainer said something that was worth all of the money I paid him, "Ken, it's always going to feel heavy." I realized I was afraid. At about 280 the bar just plain feels very heavy, no matter how strong I feel that day. I had to get past the fear.
Bench was the worst though, because I realized finally not only was I afraid of the heavy weight in my hands, but I was afraid of getting injured again. For that it was just about doing the reps and learning to "live with the fear" (cue Taledega Nights music).
Final note: I'm now at the point where there is no more comfortable progress. Every good set, even at 5-8 reps, gets not just tiring at the end but downright scary. This seems to be permanent now.
