Research and more Research! 2 of 2: Acrobatics

Wow, that might sound a little odd too in a title. BUT! Title says it all. No I AM NOT doing it for myself, though really how fun and cool would that be? Lol Anyway, this is more for Character research, several characters I have can moves and do stunts Acrobatic Athleticism. Sure again, I could look up this stuff, but watching sometimes just doesn't give me an personal view and try anything myself, i'd probably hurt myself. Again, any performers here? Street Performers (you know those amazing people who do all those stunts, bending their bodies, fire stuff, ring stuff and so on), Parkour/Free Running people, Martial artists (years since i did any of that sadly and memory doesn't hold well for what i did/can do), Rock Climbers, Hikers, and so forth you get the drift. I would like to know what stunts are nice too research, and study about, what is the difference between strength between genders like i know in some sports men can have more upper strength and woman lower strength and speed and so forth. Help is appreciated!
