That is not what i am worried about.
The thing is that the UpperTorso and the LowerTorso is connected. So when you look down and step to the side it rotates the UpperTorso and is not facing where the camera is facing anymore, but he breaks his spine instead.
Rotating the lower torso would then cause the entire character to turn, so I would rotate the lower torso and conversely rotate the lower limbs to create this effect the way you want it.
