It's ok brother. But why would you try to increase weight when you have pain?
Be gentle with yourself.
The weight you did use and your workout are outstanding !!!
Bull -I have pain every day-on different places(elbow-left,shoulder-left ,right,tennis arm,biceps tendonis,lower back ,wrist and knees)-but usually intensity of this pain is low-this is normal day for me ,so when I write in my log I call this day-"no pain day"
Sometimes during training I reveive accute pain -and that happend at "chest/back day"-I started normal with low pain(as always) and when I was by 275lbs I receive more pain,I coudn't go forward,so I stop with increase the weights
You never know what happen-a lot of time I did normal training with ,low pain and that's good,but sometimes came something other(accute pain)
