Small tip for better posing

Masterstroke

Usually posing in DAZ studio works by rotating joints in the parameter tab or the posing gizmo.
In my experience, this is not enough, to have natural believable poses.
It is better to go into your "_your install_:\DAZ 3D\Studio\My Library\data\DAZ 3D\Genesis *x\Base" and edit the translation parameters. unlock the left and right collars and set limits to -1 and 1.
Do this for the x,y and z translations.
Unlock the z-translation for the chest low, the x-translation for the upper abdomen and z and x translation for the pelvis. Do not set limits past -1 and 1. 
This give additional control over your joints and helps realistic posing.
