this just happened to me... yep, I failed on my bench miserably... 5 days ago, I did 57.5 kgs. 3 x 5 relatively easy, I could've done 3 x 7 but I had a spotter.
today was the day for 60 kgs, 2 nice 20 kg plates, one on each side, but today the gym was nearly empty cause it was late (one hour ago it was 22:30 here in germany) and had no spotter...
warm up sets were encouraging and then it went like this..
60 kgs, 1 x 4.. holy shit, no, today's not gonna work..back to 57.5
57.5, 1 x 4... WTF!! I HAD THIS WEIGHT ALREADY ....but o.k, calm down...
55 kgs... 1 x 4... -_- .... pack your things and get the fuck out of here..
