For starters, I did post this somewhere else as well and was told to widen my stance and get some Chuck Taylors.
I am looking for technique feedback. My lower back is hurting, and I was told by a certain individual that I need to fix these or I will hurt myself as I get heavier in the squat.
This is a PR for me and a landmark of making 300 lb working weight, so dont deflate my balloon too much. I am wanting constructive feedback. Please tell me what I am doing well too, dont JUST poke holes...
Thanks in advance!
