I haven't started doing it but it will be part of my idea.

-Climbing like in Parkour  or like some martial artist also do. 
-Walking up stairs or walking down.

With climbing for example..sure i can just move the character but that won't look good. How would i animate Force? To have a realistic character pushing himself up a wall would require animating the muscles so that they look like they're vibrating as they exert force. This is difficult.

If you cant get your hand on mocap :) you have to animate it in hand. One way would be to start by adding all the key frames, and then fine tune the in-betweens to fit your needs, and for the muscles you could make a morph to control the vibrating, and maybe add a noise filter/controller of some sort, if thats possible in poser(not sure if it is).

Anyway doesnt do a lot of animation so might not be the best way, but guess its one way to do it :D

Rough out the base animation first , then go back and refine by animating the morphs.  It can be done but is a lot of work . 

walking up stairs is trivial, but I daresay the concept of muscles moving under skin
won't be available in poser for many moons.  search this fourm: keyword "stairs".
I dunno what parkour is.

I think he means Parker, as in Peter Parker -aka Spiderman.

 DPHOADLEY. You're wrong:) It's Parkour. french word. It's a sport/way of life. Guys try to conquer nature by leaping, climbing, jumping off high places and landing safely. climbing tall buildings with no ropes or anything.

I dont do it but my Poser buddies(M3, James, Matt) ... i will make them do it:)
