Talk to Urologist on Anterior Pelvic Tilt

I have a bad posture as my pelvic is shifted interiorly. Reason was that there was a machine in my house and i used to do a exercise that have strengthen my rectus femoris muscles and i was only doing on front of legs that caused a imbalance and my pelvic is shifted anteriorly . Now after watching a lot of youtube videos i know a lot of things but in every video they say to do exercises after moving your pelvic posteriorly . I am unable to do that or i dont know how to do it correctly. Can you tell me whom i should visit ? which muscles should i focus for moving my pelvis in poterior position.I was a kid when i did those wrong exercises and facing bad posture from last 15 years .
