I'm pretty sure I have an anterior pelvic tilt and have started doing stretches for the past month to try and mitigate it. When I suck my stomach in/tighten my glutes while standing naturally I can reduce it significantly and make it look kinda neutral, but when I stand upright my chest flares and gives me a shell look. I'm skinny fat now but even when I was younger and more lean I always had this shape.
Does progress on this only count when I stand upright as possible and "stretch out" my spine upwards where my chest is always straight, or is my spine meant to always be somewhat compressed when standing?
