Title: Biped Joint Restrictions

On the rigged models I'm using to animate bipeds, I notice that there are joint restrictions where there shouldn't be, and no joint restrictions where they should be.

For example, the wrist cannot rotate: but the forearm can (try rotating your wrist while gripping your forearm). However, in the rigged models, the opposite is true. I cannot create animations pleasing to the eye without fixing this problem. Is there any way around this?
