Set-up: Lie on your back and grasp two gymnastic rings. Tighten your core and straighten your torso so that a straight line forms between your shoulders, hips and ankles.
Movement: Keeping a slight bend in your elbows, pull your body up and your arms out to the side. Pull until the upper arms are in a line with the torso, then lower yourself back to the start under control. The exercise is extremely challenging - to make it easier raise the height of the rings and start from a standing position. Do not use momentum.
