Other Names: Iron Traverse, Bar Traverse
This is a novelty trick that is primarily a physical challenge.
On a Bar-to-Bar rig: Start swinging facing the platform and get into a Cross, holding both fly bars. Hook your knees over one fly bar, and move your hands onto the other fly bar (so you end up in a Knee Hang Bridge). Next change your hands and bring your legs back down so you are in a Cross again, but facing the other way. They let go of one bar and swing away on the other.
