Benching went to shit yesterday. Was just all out tired, only 6 hours of sleep, long day at work, a decrease in calories all week and killing deads earlier really left me screwed for benching. I was able to do 6 sets of 3 with 250, but felt much heavier than usual. On the setup of my 7th set my srist curled back and I couldnt even unrack. Didn't have the focus to get tight. So I walked out. Like Dave Tate said, if you can't give it everything just go home.
