Stand sideways on the seat, grasp one rope with both hands leaning your back against the other, taking care to have the rope well between the shoulder blades. Put the inner centre of the left foot against the opposite rope, and fix the right foot in the same manner against the left heel. Now let go both hands, and lean well backwards, when you will be exactly balanced. When you are secure with a quiet swing, practise it while the swing is moving, until you can lie securely against the rope while you are moving freely. The balance is entirely kept by the shoulder blades against the rope, and the arms must be folded in order to throw the shoulder blades well back. If the gymnast gets alarmed, and puts his hands out to save himself, the rope slips off his back, and out he goes. (See [4].)
