Just wanna post one more time.
I moved my stance a bit outward to see if gets better but i think it´s not. It always looks like my back is curved or something in the bottom position. But in every video i watch from hookgrip or all things gym and i see those weightlifters they´re nearly completely straight through the hole squat from top to bottom and back up.
And I can´t keep my hips under me for f*** sake.
