If you take a look, you can see I cited that thread myself in my initial post. I also provided a video as a further example.
My interest was to get an explanation of "dual opposing spirals". I'm not an expert, so this idea of dual spirals seems a bit confusing to me. What are they and how does one create them? If you guys are claiming they're important to elbow power - and that aikido elbow power is different to what's been cited so far - Id like to know more about it.
Take a look at the video in the thread linked below - the split being talked about is comprised of dual opposing spirals with one going up and the other going down at the same time - the energies behind the movements should be spiraling and not linear. This is the best I can do without a face to face - sorry.
p.s. the guy in the video does not talk about spirals - IMO, he may or he may not be applying spiral energy in his splitting, but the opposing movment of up an down is present at the same time.
