Just found this amazing illustration of bat musculature:
Unlike bats though, Vokh and iVokh have an extra pair of arms whose sole function is to extend the surface area of the wing and, coincidentally, allow the legs to be longer. Of course that second pair of arms [hidden inside the wings], will require a shoulder joint that simply does not exist in our world. -sigh-
That incredible musculature belongs to a gymnast by the name of Yuri van Gelder. His nickname is ‘Lord of the Rings’ because of this:
Not the best picture, but it shows van Gelder doing the ‘Iron Cross’ on the rings. If you watch the video these still images came from, you’ll see that the rings just hang there so the resistance they provide is minimal. And that means that holding that pose, or any of the poses in that family, is down to pure will, training and strength.
To me, the most interesting thing was that the pectoral muscles are not that big. Not like this guy:
I admit the guy in that pic has a better body than most extreme body builders, but what I needed to see were muscles that actually work hard. That’s why I gave up on the body builder pics and went looking for gymnasts.
Oh, you want to know why I’m perving on, I mean researching, muscles? For the Vokh, of course. They’re flyers so the muscles across their chests have to be insanely strong, but I didn’t want them to look like birds:
So now, I have to create flight muscles that are kind of in-between the muscles of a gymnast and those of a bird. I love research. 😀
