I learned this skill at the Bangkok Solar Immersion 2016, from my master/brother/coteacher Jason Nemer. I don't recall it had a name, so "space walk" it is for now. Walking on each other's feet requires subtle listening and co-leading between the 2 partners, like a tango dance beyond language barriers.
Hence the bonus story... Over 4 years ago, yes June 2012, i was teaching an AcroYoga workshop in a gorgeous eco resort in Bali, it was pretty basic level, but one girl was amazing at flying & basing, she could do everything so at the end i asked her where she did it before…. she just smiled a bit embarrassed,… because she couldn’t understand English!… and someone helped translate that it was her first time! That's her flying on this video, Risa Nishiura one of the first certified AcroYoga teachers, it was such a joy to co-teach immersion with her in September. Now she can teach in English… and you can only imagine how amazing her acroyoga skills are growing.
Just a little reminder that AcroYoga partnership goes beyond verbal communication, when you have the wisdom to listen with heart and body <3
