Hey lads thank you all for the replies!
@MarkKO I am moving the bar off the floor mainly with my back and hamstrings. My quads have never been sore after DL's but hammies all the time. I agree my starting position is terrible.
I understand the cues, I apply them at smaller weights and it works, but for some reason when I get to heavier sets I forget everything and start doing Sumo stiff legs. I will try leaning behind the back more, and being more patient off the floor.
@chris_ottawa Agreed about shin position, I'm unable for now to stay behind the bar. I would love to be able to have my shins parallel as I know it's a necessity in Sumo. My stance is actually pretty narrow in Sumo. I tried wide but due to terrible mobility (even though I do at least one hour of mobility work every single day for the last month) I am unable to have any power from a wide stance. So I naturally use a stronger stance, which uses more back. My back is alot stronger because I can't back squat. I do Front Squats but the weight is rarely over 100 kg because I suck at them. I will start doing 10*3 on squat day. I included a video from the front in this reply.
I've watched Chris Duffins content and I know how to brace properly, thankfully also to front squats. I brace my abs even on stuff like Pull Ups and Curls to keep my spine supported. I just couldn't get air in and could feel my lower back giving out. I should stop the set there, I was going for a rep pr and I had more in me, but I called it a day at 5. I will deload now on 5/3/1 and start over with a lower training max. Patience is key, I can pull 180+ next week but I don't want to risk it with terrible technique like that. Do you think maybe I should run a cycle of 5/3/1 of blocks?
@BOTSLAYER Yeah mobility is not something I'm good at. I included a video from the front on this reply. I think as per advice of everybody in this thread i should go wider and get used to it. I do pause deads some times with light weight, I will include them again.
How does one approach locking knees out? I know they should be locked out first and agressively in Sumo, but I think I do it too early which throws me forward.
