I like to peruse the internet and "see" what the latest trends are, and I'm usually (quite) disappointed with what I discover. With my latest venture into the cyber-world, I was taken aback by how it is, that many people/systems perform the "Arm-Bar". I realize that "Logic" doesn't always apply to the martial arts, but many of the examples I found were,...exhausting (just to watch). This altered my search into seeking examples of "any" form of tuite (being applied). Surprisingly, there were few "still-shot" examples (most were really sad videos). Most all of the examples came from persons who claimed to have some manor of connection to Oyata (oh reeaally?).
The first detail that should be noted is that in every instance, the “uke” is still standing (yet their arm has been placed at a 90º relationship to the ground (and some even further). Most all are pressing down upon the upper arm, close to (if not directly upon) the shoulder to achieve submission. This amounts to being a “reversed” lever, a much more difficult, and less efficient leverage method.
