I wouldn't post the video if I wasnt looking for some feedback!You didn't ask, but I'm still seeing stuff. Do your best to not open your hand between reps. It makes the hook more painful. You can set your back bit a harder, be patient squeezing your chest forward. Look out about 14'. You've got a 4 wheel deadlift in you, easy.
The hand thing after the first rep was going from double overhand to hook. Didn't realize I was doing it every rep haha. Set everything harder. Got it.
