Aleksandr Balandin is a gymnast that is freakishly strong. He has made a name for himself because of his ability to do one thing really, really well. His strength in internal rotation and closing his shoulders is unique. He now has three elements on rings that he pioneered. All of them involve the same basic strength. From hang butterfly through to some other point. A butterfly is a straight arm pull from hang through an iron cross. This skill has been around for a while, but Balandin takes it to a whole other level, by then pressing through a maltese to either stop, press through to inverted cross, or press up to planch. Regardless of where it ends up this skill would have been considered impossible not too long ago. Think through how tough just holding a solid support on rings is, then watch the routine.
