Gymnasts begin learning back hip circles from a small cast. Right when their bodies start coming back down to the support, the coach standing on the opposite side of the bar, reaches with his arms under the rail and places one hand on the lower back and the other on the hamstring area. The hand that was on the lower back then reaches under the bar to stop the gymnast from “over rotating” the skill. The hand that was previously on the hamstring moves to the abdominal area to help in case the gymnast lacks the momentum to complete the circle.
