A normal pelvis should be tilted forward at a certain angle. Anterior pelvic tilt is a shifted pelvic position, with hips protruding backward and belly protruding forward (waist-to-hip ratio, BMI, and weight in the normal range). If you can’t see it with the naked eye, you can judge it by putting your back against the wall. If the gap between the back and the wall allows a hand to pass through, it is normal. If a very large object can pass through, then it should be anterior pelvic tilt. At this point, you need to do some exercise to correct, such as flat support, hip bridge, arrow squat and other movements can help restore the pelvis.
