Hip Circle: A very basic bar circling skill done on the uneven bars or high bar in which the body circles around the bar with the body touching the bar at the hips and the hands and arms supporting the body. There are both front hip circles (usually done out of a kip) and back hip circles (done out of a cast). Neither of these skills are used in optional competition any more. Back hip circles are a progression of free hips. Both hip circles are currently used as USA Gymnastics Compulsory skills.
