I had a strange experience yesterday in the weightroom. I'm currently on my 3rd cycle of 5/3/1 and am in the first week of it. Yesterday was deadlift day and for my last all out set I was prescribed for 270 (don't hate on the weight, I'm working on it). I look at my previous sheets and see that the week before I had gotten 265 for 8 reps and had made a side note that said "tough 8". So I'm going into this set thinking, shit, I'll be satisfied if I can get 8, but I don't know if I can get it.
So I do the set, get 8 reps and am satisfied. Someone next to me (it's a college weightroom so it gets crowded and people talk too much) says did you just pull 280 for 8 reps? To which I reply "no, it's 270"...he informs me that it is in fact 280, so I look at it again and see that he is correct. It just goes to show that the mind can limit the body and by my own stupidity, I placebo'd myself to prove that fact. Sorry if this story was anti-climatic lol
