I don't think this is a good tactic for lifting at all, and life in general. You have to have expectations of yourself or you will never reach much. If jdid says I will pull it for 5 rep he is way more liekly to get 5 than if he says, "Man, I might pull5, then I might jsut pull 1."
yeah true and if your just like well I got 1 rep so I guess thats good enough then well your happy with the minimum. But I would be pissed off if I was jdick and only got 1 rep especially after my internet rival (lol j/k) had told me that he thought I would get 5 with it, I would wanna smash 5 lol
