In this position, the forward leg acts as the weight-bearing leg and the hip is flexing as you lower into the lunge. The pelvis on that side tends to tilt backward (posterior tilt) as the femur and pelvis adjust to maintain balance with an upright trunk. At the same time, the thigh of the forward leg typically rotates outward (external rotation) to keep the knee tracking over the foot and to accommodate the sagittal and transverse plane stability required in the stance leg. So the combination you see is a posterior tilt of the forward pelvis with outward rotation of the forward thigh. The other patterns (anterior tilt, inward rotation, or no tilt) don’t match the way the hip and pelvis move to maintain alignment and stability during a lunge.
