Ruptured my bicep tendon removing the door pad on a truck.
I tore my bicep lifting a welding machine into a shipping container. There was like an iron loop at the end and I pulled with one finger, using the hand I supinate on deads. I mean I've held almost 1K on a very short rack dead with a mixed grip with no tears. I must have slightly bended the arm. Docs didn't want to operate but I insisted and I'm extremely glad I did, otherwise there would be zero bicep left (already had very small and short bis).
