OK, there was this karate dude at my old gym. He would do ALL sorts of weird shit. One day I saw him grab onto the chinup bar that runs along the top of the big cable cross over machine. He then swung himself up and over the top of the machine (like a gymnast on the uneven bars). So now he has his stomach laying on the big beam that connects the two stations together. Then he starts doing crazy exercises on top of the machine, stretching himself out and stuff.
