What is the hardest suspension? Well I guess it all depends on you point of view. For some it’s all about pain and endurance. For others it has more to do with rigging complexity or possibly skill level. For me personally, I think Jussi aka Dr Zacharias Snake solving of a Rubik’s Cube in less than 2 minutes while swinging, spinning and hanging from his knees has got to be one of the most impressive feats I’ve seen in a while.
