brad johnson has an article on dragondoor called "gymnastic tension exercises". in this article he gives tips on how to train for an iron cross. he mentions that you can work on the cross at home if you have no rings by placing 2 stools side by side and doing a cross between them and over time moving them further away from each other until just your hands are resting on them.
i tried this yesterday with two stools and it felt to me as if it could work. currently the stools are resting under my elbows and upper arms. at the momment im just trying to get the feel for the cross and master the technique.
does anyone see any problems with learning the cross in this way and would it even work?
