Hip anteverted?

Good question. In fact, you don't want the pelvis to be maximally anteverted. The guideline I use is "put your bottom back in the chair," which results in a mild anteversion or in any case prevents a retroverted pelvis. If you antevert a great deal, you will probably have used up whatever flexibility you have at L5-S1 and then be swaying when you reach your back to contact the backrest.
