I always followed proper form and didn't ego lift, even though my deadlifts were the highest weight.

I think on retrospect deadlifts may have been my issue to, I did the deadlifts that day and later remember going to pickup something off the ground and getting the issue. Not sure if the deadlift was the cause, but I always thought my muscles were sore/tired and lax, thus when I went to lift the thing my lower back stability was compromised.

I'll try Romanian deadlifts and those other exercises, thanks for that suggestion.
