Form check #3 sent in. A deadlift this time!
So my boy does a lot well, bar position over midfoot, neutral spine, shins just forward of vertical, bar under scap ect.
Only a couple things I can spot from the video and one I'm less sure of. One thing for sure - I would say your bracing and setting is a little loose, you hold yourself well but don't take much time to create tension on the bar or set your brace. Before the pull you should feel like if the bar was taken away you would fall back from the amount of tension out into the bar. A belt may serve to help with the cue but just a matter of getting in air (I myself hold the bar, raise my hips to take in plenty of air and then drop back into position). The other point that I am less sure of is your foot stance. Hard to tell from the angle but it looks a little overly narrow and your foot looks overly externally rotated, optimally is widen slightly and straighten just slightly to allow optimal force output, however if need more footage to say. Over all a strong pull, just the brace and positioning I'd say foremost and possible upper back tightness to look into - belted work as an assistance/ main movement may help.
