You need to be pulling the bar up your legs, at the start of every lift the bar is not moving upwards, it is moving inwards, this is wasted movement, and the extra distance away from your centre will increase shear forces in the back.Hi this is my deadlift, I'm trying to keep back straight and push through feet. I cant seem to keep my back completely flat.......
Any comments and tips appreciated.....
You don't look to bad in terms of proportions and positioning but just need to lock down some of the cues. Another key element is activating your lats. When you are getting tight on the bar you want to try and imagine putting your elbows in to your pockets, really lock yourself in before lifting.
