Aaron, We all do stuff we shouldn’t have done from time to time. As long as your not hurt it wasn’t that big of a fuck up. But it is really showing a weakness in your pull, you need to work on taking the slack out and bracing. Your back should not round that much before the bar breaks the floor. Taking the slack and bracing with fix this.
Think about have 50% of the weight on the bar already in your hands and lats before you actually pull.
