Elliot is a strong dude but one small issue I have with his form is that he's shooting his hips during the first pull. You want to maintain a little knee bend as the bar passes the knee and then fiercely extend the knee and the hips once the torso is in an upright position, all the while keeping the bar in close to the body with the lats. You'll notice that Elliot catches the bar forward of his starting position because allowing his knees to straighten during the first-pull has lead to him making his second-pull a little early, before he was fully upright (or even slightly leaning back). Ideally, you want the bar path to be vertical or even slightly back at the catch.
Allowing your knees to straighten during the first pull also has the effect of slowing the vertical progress of the bar because the knees have to rebend more prior to the second pull.
So, just think about maintaining a little knee bend during the first part of the lift. Make the first pull use more quads than you would for a deadlift.
You'll need to hook-grip too or you can easily lose the bar during the second-pull.
