One trick is to make sure you have "limits" turned on when you set the initial parameters for the pose. This way you can try to achieve the pose inside the set joint limitations. Once you've got close enough turn the limits off and finalise the pose with a few minor tweaks, that will prevent a lot of the fracturing and crushing that happens. Not all of it, but it cuts down a lot. One temptation with posing is to forget the collar movement and just shift the shoulder right through a huge arc, (when you move your arm back and forwards or to the side it's the shoulder (collar) that actually moves, the upper arm twists) and to forget that wrists simple don't rotate, only the forarm. Another thing people sometimes forget is that the upper arm (shoulder) and shoulder (collar) also have a full range of movements and they tend to just bend twist one part which results in some very strange effects. :) For example. Scratching your head. The shoulder (collar) moves up (side slides), then the upper arm (shoulder) twists, the forarm twists and bends (sometimes, though mostly not), the wrist bends and the fingers scratch. I've seen so many poses with hands on head that have bent the upper arm (shoulder) through 130 degrees then twisted the forarm and wrist that I've started whinceing in pain when I see it. Try it and see how much it hurts. About the best way to achieve a pose is to try it yourself. Study which parts of your anatomy move and then try to match it on the poser figure. I know it sounds wierd and you'll probably get some odd looks from the family, but it does help. :)
