Good to see that you are back to lifting again. Good call to omit the chains on this one. Your technique is getting better and better. You can see the upper back position and effort to arch hard on the set up. I would like to see more effort to drive your chest into the bar on the way down. You are not collapsing, but you aren’t driving up either. You’re just staying the same. Even if your chest only goes up 1 mm drive it up to meet the bar while bringing it down.
