tl;dr:"This post is about anterior pelvic tilt, the most common posture dysfunction... How do you know if you have an anterior pelvic tilt? Look at your belt. If you belt points towards the floor, you have an anterior pelvic tilt. Or, look sideways in the mirror. does your butt stick out? Chances are that you have an anterior pelvic tilt. I’m gonna break bad posture in 2 sections, lower body and upper body. The lower body influences the upper body, but upper body doesn’t always influence the lower body."
