This is so true.
IMHO the deadlift is the biggest mental lift that there is. I remember the first time I pulled 510 was in a meet. Id missed it before in training but I managed to hit the lift, just.
A couple of weeks later I thought I would have another crack at it. I loaded it up and pulled it easy. When I went to unrack it I noticed I actually pulled 530lbs by mistake as I added it up wrong.
Because I ‘knew’ I could lift it there was no psychological barrier.[/quote]
That reminded I read a while back how Soviet coaches/sports psychologists would change the markings on the plates of their weightlifters at times to make them believe they were lifting more/less than they thought. Interesting stuff
