I must have been in junior high or high school when I first saw a gymnast doing the iron cross move on the rings. I was then, and still am, extremely impressed by the muscle strength it obviously takes to execute the move. As difficult as it seemed to be, when I was young I always thought that, at least theoretically if I chose to work out long enough and hard enough I might be able to do one too. I never did of course. Now, with a snapped bicep muscle and a shoulder in need of rotator cuff repair, I can’t even fool myself into thinking I could do one. In fact just thinking about trying one makes my arm hurt! It’s much less painful to just admire this magpie doing an aerial version.
