This is 80% of my max. Recently I have been trying to stay more vertical during the extension and keeping the bar over the base of my feet throughout the lift. This week I began using a much different starting position than before; I now start with the bar slightly off my shins (instead of touching) and with my back much closer to horizontal than before. I have a bad habit of pulling my elbows back instead of up during the third pull; in this video I missed the first rep because of this, then made the next two. I also need to start using my shoulders more during the third pull. I'd appreciate any tips you all may have - thanks!
