I was doing flat dumbell bench press doing 160 lbs combined. Some guy walks by putting 30 lb dumbells away and hits my right dumbell halfway up on a rep. It was just enough force to put my stablizing mucles off balance and 80 lb weight goes over my head and crashes to the floor. It was an accident, but I was pissed. Can't people be cautious when walking around people in the middle of a set?
Anyone else have any horror stories?
