Back pain from pumps? I do all my biceps work seated, it doesn't matter how good you are - standing will always involve the back to an extent.
Just a thought.
It came during the rope extensions and I still have it today. I can't explain it, other than maybe I hurt them during deadlifts the other day. Glutes are absolutely rock hard so maybe too tight and need to foam role plus massage
