No I know the the rounding of my back doesnt have to do with weak abs, tight abs would do that. What I was saying is tight hammies is the reason I probably can't keep the back arched. From a pic, 2 people said I have a posterior tilt (one of them were you, hehe)
I don't think I ever said that. I think you showed me a picture of a silhouette with an anterior pelvic tilt and I told you that it was displaying an anterior pelvic tilt.
