I've rigged from Blender, via Poser.  Best way I've found is to "cut" the model into separate OBJ files for each body part and combine the collection within Poser.  Otherwise, you run into Blender's poor handling of vertex groups in the OBJ.

Of course if you really don't need to use Poser, you can -- as was pointed out -- rig in Blender.  But I've never gone down that path since I target my models for Poser.
