But this posture makes your pelvis rock forward into an anterior pelvic tilt, which consequently creates an increased lumbar curve (lordosis). Unfortunately, other tissues such as the muscles described above adapt to this posture over time, which contributes to back pain and injury.
This will cause the hip to tilt forward and the lumbar curvature to increase (excessive lordosis). So basically, anterior pelvic tilt potentially leads to lower back pain, hip pain (because of the rotated femurs), knee pain (because of the knock-knee position) and flat feet.
