true that to what bfold said. Also i'd like to add that it can mentally break you OR make you. Knowing that you are dealing with max poundages can pump you up pretty good. well me anyway.
exactly man, i remember about 3 months ago i was stuck on 315 and it haunted me like none other because everytime i would try it, i'd get it half way and it'd ruin my whole day! but eventually i got passed it. i do think the chart is pretty accurate though, guess it does depend on the person also.
It works the opposite for me. I do better if it's all a surprise...that way I haven't mentally set a limit for myself. I want to walk up to a 450 pound deadlift and say, "To hell with it, let's see if it'll move!" not, "Oh shit...this is my max...I've never done this in the gym before...oh shit."
Either way, charts are bunk. If you haven't lifted it, you can't say it's your max. Period. They are ok as a training tool, and that's it.
Very true!!! I just like to use charts to ball-park weights to use for my building sets. I feel that they are pretty accurate for me. I never max out, so I cannot tell you where my 1 rep max stands. . . .I can give you an estimate .
