Looking good. Nothing really stands out as wrong. A few small tweaks may help you but you’re on track to make all kinds of gains
Try going wider and/or getting your hips closer to the bar in the horizontal plane in the start position. The wider you go the more hate you get lel
Maybe try to get faster off the floor. Play with different foot/toe angles and how close your shins start to the bar and see if you can get more speed off the floor. Maybe just “trying” to pull faster will get the desired result.
Just because it’s sumo doesn’t mean you have any excuse to be slow off the floor especially with lower percentages like in your vid. That’s more the case for those upright torso sexy sumo looking motherfuckers.
