Yes yes, I know, it's a terrible looking lift. I'm all for form breaking down at maximum weights but if you look I didn't even set the back tight from the very start. I had no chance of keeping it tight. It is a bit disappointing to see that, especially when I usually get so tight and arched for the start of the Oly lifts. I will make sure to work on that when I attempt 600.
Keep in mind I deadlift heavy maybe once every 3-4 months, but I recently decided I would like to hit 300kg/660 so I'm doing a maximum single every 2 weeks till I get there. Linear progression ftw.
