Keep the hips level.
If one hip visibly drops or the pelvis rotates every step, the stance leg is collapsing instead of supporting you — a common source of knee and IT-band complaints. Note this one needs a front view to judge; from the side it is always marked insufficient. Level hips with a neutral pelvis and active glutes is the target.
